Research Paper Introduction

Research Paper Introduction

Research paper introduction is the first section of a research paper that provides an overview of the study, its purpose, and the research question (s) or hypothesis (es) being investigated. It typically includes background information about the topic, a review of previous research in the field, and a statement of the research objectives. The introduction is intended to provide the reader with a clear understanding of the research problem, why it is important, and how the study will contribute to existing knowledge in the field. It also sets the tone for the rest of the paper and helps to establish the author’s credibility and expertise on the subject.

How to Write Research Paper Introduction

Writing an introduction for a research paper can be challenging because it sets the tone for the entire paper. Here are some steps to follow to help you write an effective research paper introduction:

  • Start with a hook : Begin your introduction with an attention-grabbing statement, a question, or a surprising fact that will make the reader interested in reading further.
  • Provide background information: After the hook, provide background information on the topic. This information should give the reader a general idea of what the topic is about and why it is important.
  • State the research problem: Clearly state the research problem or question that the paper addresses. This should be done in a concise and straightforward manner.
  • State the research objectives: After stating the research problem, clearly state the research objectives. This will give the reader an idea of what the paper aims to achieve.
  • Provide a brief overview of the paper: At the end of the introduction, provide a brief overview of the paper. This should include a summary of the main points that will be discussed in the paper.
  • Revise and refine: Finally, revise and refine your introduction to ensure that it is clear, concise, and engaging.

Structure of Research Paper Introduction

The following is a typical structure for a research paper introduction:

  • Background Information: This section provides an overview of the topic of the research paper, including relevant background information and any previous research that has been done on the topic. It helps to give the reader a sense of the context for the study.
  • Problem Statement: This section identifies the specific problem or issue that the research paper is addressing. It should be clear and concise, and it should articulate the gap in knowledge that the study aims to fill.
  • Research Question/Hypothesis : This section states the research question or hypothesis that the study aims to answer. It should be specific and focused, and it should clearly connect to the problem statement.
  • Significance of the Study: This section explains why the research is important and what the potential implications of the study are. It should highlight the contribution that the research makes to the field.
  • Methodology: This section describes the research methods that were used to conduct the study. It should be detailed enough to allow the reader to understand how the study was conducted and to evaluate the validity of the results.
  • Organization of the Paper : This section provides a brief overview of the structure of the research paper. It should give the reader a sense of what to expect in each section of the paper.

Research Paper Introduction Examples

Research Paper Introduction Examples could be:

Example 1: In recent years, the use of artificial intelligence (AI) has become increasingly prevalent in various industries, including healthcare. AI algorithms are being developed to assist with medical diagnoses, treatment recommendations, and patient monitoring. However, as the use of AI in healthcare grows, ethical concerns regarding privacy, bias, and accountability have emerged. This paper aims to explore the ethical implications of AI in healthcare and propose recommendations for addressing these concerns.

Example 2: Climate change is one of the most pressing issues facing our planet today. The increasing concentration of greenhouse gases in the atmosphere has resulted in rising temperatures, changing weather patterns, and other environmental impacts. In this paper, we will review the scientific evidence on climate change, discuss the potential consequences of inaction, and propose solutions for mitigating its effects.

Example 3: The rise of social media has transformed the way we communicate and interact with each other. While social media platforms offer many benefits, including increased connectivity and access to information, they also present numerous challenges. In this paper, we will examine the impact of social media on mental health, privacy, and democracy, and propose solutions for addressing these issues.

Example 4: The use of renewable energy sources has become increasingly important in the face of climate change and environmental degradation. While renewable energy technologies offer many benefits, including reduced greenhouse gas emissions and energy independence, they also present numerous challenges. In this paper, we will assess the current state of renewable energy technology, discuss the economic and political barriers to its adoption, and propose solutions for promoting the widespread use of renewable energy.

Purpose of Research Paper Introduction

The introduction section of a research paper serves several important purposes, including:

  • Providing context: The introduction should give readers a general understanding of the topic, including its background, significance, and relevance to the field.
  • Presenting the research question or problem: The introduction should clearly state the research question or problem that the paper aims to address. This helps readers understand the purpose of the study and what the author hopes to accomplish.
  • Reviewing the literature: The introduction should summarize the current state of knowledge on the topic, highlighting the gaps and limitations in existing research. This shows readers why the study is important and necessary.
  • Outlining the scope and objectives of the study: The introduction should describe the scope and objectives of the study, including what aspects of the topic will be covered, what data will be collected, and what methods will be used.
  • Previewing the main findings and conclusions : The introduction should provide a brief overview of the main findings and conclusions that the study will present. This helps readers anticipate what they can expect to learn from the paper.

When to Write Research Paper Introduction

The introduction of a research paper is typically written after the research has been conducted and the data has been analyzed. This is because the introduction should provide an overview of the research problem, the purpose of the study, and the research questions or hypotheses that will be investigated.

Once you have a clear understanding of the research problem and the questions that you want to explore, you can begin to write the introduction. It’s important to keep in mind that the introduction should be written in a way that engages the reader and provides a clear rationale for the study. It should also provide context for the research by reviewing relevant literature and explaining how the study fits into the larger field of research.

Advantages of Research Paper Introduction

The introduction of a research paper has several advantages, including:

  • Establishing the purpose of the research: The introduction provides an overview of the research problem, question, or hypothesis, and the objectives of the study. This helps to clarify the purpose of the research and provide a roadmap for the reader to follow.
  • Providing background information: The introduction also provides background information on the topic, including a review of relevant literature and research. This helps the reader understand the context of the study and how it fits into the broader field of research.
  • Demonstrating the significance of the research: The introduction also explains why the research is important and relevant. This helps the reader understand the value of the study and why it is worth reading.
  • Setting expectations: The introduction sets the tone for the rest of the paper and prepares the reader for what is to come. This helps the reader understand what to expect and how to approach the paper.
  • Grabbing the reader’s attention: A well-written introduction can grab the reader’s attention and make them interested in reading further. This is important because it can help to keep the reader engaged and motivated to read the rest of the paper.
  • Creating a strong first impression: The introduction is the first part of the research paper that the reader will see, and it can create a strong first impression. A well-written introduction can make the reader more likely to take the research seriously and view it as credible.
  • Establishing the author’s credibility: The introduction can also establish the author’s credibility as a researcher. By providing a clear and thorough overview of the research problem and relevant literature, the author can demonstrate their expertise and knowledge in the field.
  • Providing a structure for the paper: The introduction can also provide a structure for the rest of the paper. By outlining the main sections and sub-sections of the paper, the introduction can help the reader navigate the paper and find the information they are looking for.

The introduction leads the reader from a general subject area to a particular topic of inquiry. It establishes the scope, context, and significance of the research being conducted by summarizing current understanding and background information about the topic, stating the purpose of the work in the form of the research problem supported by a hypothesis or a set of questions, explaining briefly the methodological approach used to examine the research problem, highlighting the potential outcomes your study can reveal, and outlining the remaining structure and organization of the paper.

Importance of a Good Introduction

Think of the introduction as a mental road map that must answer for the reader these four questions:

  • What was I studying?
  • Why was this topic important to investigate?
  • What did we know about this topic before I did this study?
  • How will this study advance new knowledge or new ways of understanding?

According to Reyes, there are three overarching goals of a good introduction: 1) ensure that you summarize prior studies about the topic in a manner that lays a foundation for understanding the research problem; 2) explain how your study specifically addresses gaps in the literature, insufficient consideration of the topic, or other deficiency in the literature; and, 3) note the broader theoretical, empirical, and/or policy contributions and implications of your research.

A well-written introduction is important because, quite simply, you never get a second chance to make a good first impression. The opening paragraphs of your paper will provide your readers with their initial impressions about the logic of your argument, your writing style, the overall quality of your research, and, ultimately, the validity of your findings and conclusions. A vague, disorganized, or error-filled introduction will create a negative impression, whereas, a concise, engaging, and well-written introduction will lead your readers to think highly of your analytical skills, your writing style, and your research approach. All introductions should conclude with a brief paragraph that describes the organization of the rest of the paper.

Structure and Writing Style

I.  Structure and Approach

The introduction is the broad beginning of the paper that answers three important questions for the reader:

  • What is this?
  • Why should I read it?
  • What do you want me to think about / consider doing / react to?

Think of the structure of the introduction as an inverted triangle of information that lays a foundation for understanding the research problem. Organize the information so as to present the more general aspects of the topic early in the introduction, then narrow your analysis to more specific topical information that provides context, finally arriving at your research problem and the rationale for studying it [often written as a series of key questions to be addressed or framed as a hypothesis or set of assumptions to be tested] and, whenever possible, a description of the potential outcomes your study can reveal.

These are general phases associated with writing an introduction: 1.  Establish an area to research by:

  • Highlighting the importance of the topic, and/or
  • Making general statements about the topic, and/or
  • Presenting an overview on current research on the subject.

2.  Identify a research niche by:

  • Opposing an existing assumption, and/or
  • Revealing a gap in existing research, and/or
  • Formulating a research question or problem, and/or
  • Continuing a disciplinary tradition.

3.  Place your research within the research niche by:

  • Stating the intent of your study,
  • Outlining the key characteristics of your study,
  • Describing important results, and
  • Giving a brief overview of the structure of the paper.

NOTE:   It is often useful to review the introduction late in the writing process. This is appropriate because outcomes are unknown until you've completed the study. After you complete writing the body of the paper, go back and review introductory descriptions of the structure of the paper, the method of data gathering, the reporting and analysis of results, and the conclusion. Reviewing and, if necessary, rewriting the introduction ensures that it correctly matches the overall structure of your final paper.

II.  Delimitations of the Study

Delimitations refer to those characteristics that limit the scope and define the conceptual boundaries of your research . This is determined by the conscious exclusionary and inclusionary decisions you make about how to investigate the research problem. In other words, not only should you tell the reader what it is you are studying and why, but you must also acknowledge why you rejected alternative approaches that could have been used to examine the topic.

Obviously, the first limiting step was the choice of research problem itself. However, implicit are other, related problems that could have been chosen but were rejected. These should be noted in the conclusion of your introduction. For example, a delimitating statement could read, "Although many factors can be understood to impact the likelihood young people will vote, this study will focus on socioeconomic factors related to the need to work full-time while in school." The point is not to document every possible delimiting factor, but to highlight why previously researched issues related to the topic were not addressed.

Examples of delimitating choices would be:

  • The key aims and objectives of your study,
  • The research questions that you address,
  • The variables of interest [i.e., the various factors and features of the phenomenon being studied],
  • The method(s) of investigation,
  • The time period your study covers, and
  • Any relevant alternative theoretical frameworks that could have been adopted.

Review each of these decisions. Not only do you clearly establish what you intend to accomplish in your research, but you should also include a declaration of what the study does not intend to cover. In the latter case, your exclusionary decisions should be based upon criteria understood as, "not interesting"; "not directly relevant"; “too problematic because..."; "not feasible," and the like. Make this reasoning explicit!

NOTE:   Delimitations refer to the initial choices made about the broader, overall design of your study and should not be confused with documenting the limitations of your study discovered after the research has been completed.

ANOTHER NOTE: Do not view delimitating statements as admitting to an inherent failing or shortcoming in your research. They are an accepted element of academic writing intended to keep the reader focused on the research problem by explicitly defining the conceptual boundaries and scope of your study. It addresses any critical questions in the reader's mind of, "Why the hell didn't the author examine this?"

III.  The Narrative Flow

Issues to keep in mind that will help the narrative flow in your introduction :

  • Your introduction should clearly identify the subject area of interest . A simple strategy to follow is to use key words from your title in the first few sentences of the introduction. This will help focus the introduction on the topic at the appropriate level and ensures that you get to the subject matter quickly without losing focus, or discussing information that is too general.
  • Establish context by providing a brief and balanced review of the pertinent published literature that is available on the subject. The key is to summarize for the reader what is known about the specific research problem before you did your analysis. This part of your introduction should not represent a comprehensive literature review--that comes next. It consists of a general review of the important, foundational research literature [with citations] that establishes a foundation for understanding key elements of the research problem. See the drop-down menu under this tab for " Background Information " regarding types of contexts.
  • Clearly state the hypothesis that you investigated . When you are first learning to write in this format it is okay, and actually preferable, to use a past statement like, "The purpose of this study was to...." or "We investigated three possible mechanisms to explain the...."
  • Why did you choose this kind of research study or design? Provide a clear statement of the rationale for your approach to the problem studied. This will usually follow your statement of purpose in the last paragraph of the introduction.

IV.  Engaging the Reader

A research problem in the social sciences can come across as dry and uninteresting to anyone unfamiliar with the topic . Therefore, one of the goals of your introduction is to make readers want to read your paper. Here are several strategies you can use to grab the reader's attention:

  • Open with a compelling story . Almost all research problems in the social sciences, no matter how obscure or esoteric , are really about the lives of people. Telling a story that humanizes an issue can help illuminate the significance of the problem and help the reader empathize with those affected by the condition being studied.
  • Include a strong quotation or a vivid, perhaps unexpected, anecdote . During your review of the literature, make note of any quotes or anecdotes that grab your attention because they can used in your introduction to highlight the research problem in a captivating way.
  • Pose a provocative or thought-provoking question . Your research problem should be framed by a set of questions to be addressed or hypotheses to be tested. However, a provocative question can be presented in the beginning of your introduction that challenges an existing assumption or compels the reader to consider an alternative viewpoint that helps establish the significance of your study. 
  • Describe a puzzling scenario or incongruity . This involves highlighting an interesting quandary concerning the research problem or describing contradictory findings from prior studies about a topic. Posing what is essentially an unresolved intellectual riddle about the problem can engage the reader's interest in the study.
  • Cite a stirring example or case study that illustrates why the research problem is important . Draw upon the findings of others to demonstrate the significance of the problem and to describe how your study builds upon or offers alternatives ways of investigating this prior research.

NOTE:   It is important that you choose only one of the suggested strategies for engaging your readers. This avoids giving an impression that your paper is more flash than substance and does not distract from the substance of your study.

Writing Tip

Avoid the "Dictionary" Introduction

Giving the dictionary definition of words related to the research problem may appear appropriate because it is important to define specific terminology that readers may be unfamiliar with. However, anyone can look a word up in the dictionary and a general dictionary is not a particularly authoritative source because it doesn't take into account the context of your topic and doesn't offer particularly detailed information. Also, placed in the context of a particular discipline, a term or concept may have a different meaning than what is found in a general dictionary. If you feel that you must seek out an authoritative definition, use a subject specific dictionary or encyclopedia [e.g., if you are a sociology student, search for dictionaries of sociology]. A good database for obtaining definitive definitions of concepts or terms is Credo Reference .

Another Writing Tip

When Do I Begin?

A common question asked at the start of any paper is, "Where should I begin?" An equally important question to ask yourself is, "When do I begin?" Research problems in the social sciences rarely rest in isolation from history. Therefore, it is important to lay a foundation for understanding the historical context underpinning the research problem. However, this information should be brief and succinct and begin at a point in time that illustrates the study's overall importance. For example, a study that investigates coffee cultivation and export in West Africa as a key stimulus for local economic growth needs to describe the beginning of exporting coffee in the region and establishing why economic growth is important. You do not need to give a long historical explanation about coffee exports in Africa. If a research problem requires a substantial exploration of the historical context, do this in the literature review section. In your introduction, make note of this as part of the "roadmap" [see below] that you use to describe the organization of your paper.

Introductions. The Writing Center. University of North Carolina; “Writing Introductions.” In Good Essay Writing: A Social Sciences Guide . Peter Redman. 4th edition. (London: Sage, 2011), pp. 63-70.

Yet Another Writing Tip

Always End with a Roadmap

The final paragraph or sentences of your introduction should forecast your main arguments and conclusions and provide a brief description of the rest of the paper [the "roadmap"] that let's the reader know where you are going and what to expect. A roadmap is important because it helps the reader place the research problem within the context of their own perspectives about the topic. In addition, concluding your introduction with an explicit roadmap tells the reader that you have a clear understanding of the structural purpose of your paper. In this way, the roadmap acts as a type of promise to yourself and to your readers that you will follow a consistent and coherent approach to addressing the topic of inquiry. Refer to it often to help keep your writing focused and organized.

  • If you are writing in a new discipline, you should always make sure to ask about conventions and expectations for introductions, just as you would for any other aspect of the essay. For example, while it may be acceptable to write a two-paragraph (or longer) introduction for your papers in some courses, instructors in other disciplines, such as those in some Government courses, may expect a shorter introduction that includes a preview of the argument that will follow.  
  • In some disciplines (Government, Economics, and others), it’s common to offer an overview in the introduction of what points you will make in your essay. In other disciplines, you will not be expected to provide this overview in your introduction.  
  • Avoid writing a very general opening sentence. While it may be true that “Since the dawn of time, people have been telling love stories,” it won’t help you explain what’s interesting about your topic.  
  • Avoid writing a “funnel” introduction in which you begin with a very broad statement about a topic and move to a narrow statement about that topic. Broad generalizations about a topic will not add to your readers’ understanding of your specific essay topic.  
  • Avoid beginning with a dictionary definition of a term or concept you will be writing about. If the concept is complicated or unfamiliar to your readers, you will need to define it in detail later in your essay. If it’s not complicated, you can assume your readers already know the definition.  
  • Avoid offering too much detail in your introduction that a reader could better understand later in the paper.

what to put in the introduction of a research paper

Want to know how to write a research paper introduction that dazzles?

Struggling to hook your reader in with your opening sentences?

Crafting a captivating research paper introduction can be the difference between a mediocre paper and an outstanding one. The introduction sets the tone for the entire paper, and if it fails to capture the reader’s attention, your hard work may go unnoticed. In this post, we’ll explore some techniques for crafting a compelling introduction that will hook your reader from the very beginning. From using statistics to posing thought-provoking questions, we’ll show you how to reel in your reader hook, line, and sinker.

So, grab your pen and paper, and let’s get started!

What Makes a Captivating Introduction?

When it comes to writing a research paper, the introduction is everything. It’s the first glimpse your audience gets of what’s to come and the determining factor as to whether they continue reading or move on. A captivating introduction should immediately grab the reader’s attention and draw them in, enticing them to learn more about your unique research. It should be thought-provoking, relevant and informative.

By connecting with your audience and allowing them to identify with your work, you create an emotional investment from the start. You might be thinking that a research paper introduction only needs to provide cold, hard information, but this is missing half of the picture. If you can blend quality information with skilful writing, you’ll ensure that your reader remains engaged and open to your argument throughout the entirety of your paper. So, when crafting your introduction, strive to be engaging and focus on making a strong impression.

Pre-Writing Strategies for Crafting an Effective Introduction

Crafting that quality introduction begins even before you put pen to paper (or finger to keyboard). Start planning mentally with the following tips:

  • Try to ‘visualise’ your research from beginning to end. Your paper is your means of guiding the reader through that research. Imagine that you’re going to take the reader by the hand and walk them through it. What do they need to know before you set off? What’s going to convince them to take the journey? Thinking along these lines will set you in the right frame of mind for writing.
  • Remember that your introduction acts as a roadmap, directing readers towards your key points and arguments and letting them know what to expect. Thinking in terms of providing a map will clarify your writing decisions.
  • Think clearly and with confidence. If your introduction is vague, lacks sufficient information or is otherwise unconvincing, your reader may become disengaged from the outset.

How to Write a Research Paper Introduction with Clarity and Style

With your thoughts flowing, you can now turn to the act of writing your introduction, Each of the sections outlined below will typically take up one paragraph of your intro, with the exception of the literature review, which is likely to occupy several.

  • Always keep in mind that anyone can read your paper, not just an academically literate audience. With this in mind, begin by introducing your subject generally, ideally in a way that a layperson could understand. If you overwhelm your reader with technical language from the outset, they may become frustrated and stop reading.
  • Your subject introduction might include some historical context, or a brief overview of the significance of your field. Either way, prepare to narrow down that general overview to your specific research. Let the reader know what you’re working on.
  • More importantly, explain why your research is important. Perhaps you’re seeking to fill in a gap in the historical record, or are working on medication that could help people with a specific illness. Be clear about why your research could make a difference and why the reader should pay attention to it.

Literature Review

  • At this point, you can go into more detail on existing research efforts in your field with a literature review. Find out all about these and how to construct them in our complete guide . (Add link to lit. review post once it’s published)

Research Intention

  • Here, go into detail on the intention of your research. If you have a hypothesis, state it, or if you’re approaching your work with a broader, more open research question, then set it out.
  • Briefly discuss your research methods, keeping in mind that you’ll probably be writing a complete methodology section later.

Paper Overview

  • In this optional section, provide a brief overview of your whole paper by section, outlining what you intend to do in each of them – for example ‘In Section 4 we describe our methodology in detail. In Section 5 we present our data without analysis. In Section 6 we conduct an analysis of the data.’

As we mentioned before, balancing quality information with skilful, engaging writing can grab your reader’s attention right from the start. One way to do this is through a hook. But what makes a good hook?

  • It could be a statistic, taken either from your own research or elsewhere. Naturally, it should be relevant to your topic, as well as thought-provoking – a figure that makes your reader sit up and take notice of what you’re about to say. For example, if your paper focuses on marine plastics, then consider using a statistic to illustrate just how prevalent the problem is.
  • It might be a reference to a current event that is garnering a lot of attention. If you can connect that event to your research, and prove its social relevance, you can potentially earn more readers than you might expect.
  • You could even use a quotation, for example from a respected academic in your field. This can act as a point of inspiration for both you and your reader. There’s nothing stopping you from being creative in your introduction, and if your hook is directly relevant to your research, then it can take whatever shape you like.

Final Thoughts

The introductory paragraphs of your research paper are your chance to make a great first impression. By crafting a captivating introduction, you can draw your reader in and set the stage for an outstanding paper. From using powerful statistics to posing thought-provoking questions, there are many techniques you can use to hook your reader from the very beginning. So don’t be afraid to get creative and experiment with different approaches until you find one that works for you.

With these tips in mind, you’ll know how to write a research paper introduction that will leave your audience hooked, lined, and sunk!

Writing an Introduction for a Scientific Paper

Dr. michelle harris, dr. janet batzli, biocore.

This section provides guidelines on how to construct a solid introduction to a scientific paper including background information, study question , biological rationale, hypothesis , and general approach . If the Introduction is done well, there should be no question in the reader’s mind why and on what basis you have posed a specific hypothesis.

Broad Question : based on an initial observation (e.g., “I see a lot of guppies close to the shore. Do guppies like living in shallow water?”). This observation of the natural world may inspire you to investigate background literature or your observation could be based on previous research by others or your own pilot study. Broad questions are not always included in your written text, but are essential for establishing the direction of your research.

Background Information : key issues, concepts, terminology, and definitions needed to understand the biological rationale for the experiment. It often includes a summary of findings from previous, relevant studies. Remember to cite references, be concise, and only include relevant information given your audience and your experimental design. Concisely summarized background information leads to the identification of specific scientific knowledge gaps that still exist. (e.g., “No studies to date have examined whether guppies do indeed spend more time in shallow water.”)

Testable Question : these questions are much more focused than the initial broad question, are specific to the knowledge gap identified, and can be addressed with data. (e.g., “Do guppies spend different amounts of time in water <1 meter deep as compared to their time in water that is >1 meter deep?”)

Biological Rationale : describes the purpose of your experiment distilling what is known and what is not known that defines the knowledge gap that you are addressing. The “BR” provides the logic for your hypothesis and experimental approach, describing the biological mechanism and assumptions that explain why your hypothesis should be true.

The biological rationale is based on your interpretation of the scientific literature, your personal observations, and the underlying assumptions you are making about how you think the system works. If you have written your biological rationale, your reader should see your hypothesis in your introduction section and say to themselves, “Of course, this hypothesis seems very logical based on the rationale presented.”

  • A thorough rationale defines your assumptions about the system that have not been revealed in scientific literature or from previous systematic observation. These assumptions drive the direction of your specific hypothesis or general predictions.
  • Defining the rationale is probably the most critical task for a writer, as it tells your reader why your research is biologically meaningful. It may help to think about the rationale as an answer to the questions— how is this investigation related to what we know, what assumptions am I making about what we don’t yet know, AND how will this experiment add to our knowledge? *There may or may not be broader implications for your study; be careful not to overstate these (see note on social justifications below).
  • Expect to spend time and mental effort on this. You may have to do considerable digging into the scientific literature to define how your experiment fits into what is already known and why it is relevant to pursue.
  • Be open to the possibility that as you work with and think about your data, you may develop a deeper, more accurate understanding of the experimental system. You may find the original rationale needs to be revised to reflect your new, more sophisticated understanding.
  • As you progress through Biocore and upper level biology courses, your rationale should become more focused and matched with the level of study e ., cellular, biochemical, or physiological mechanisms that underlie the rationale. Achieving this type of understanding takes effort, but it will lead to better communication of your science.

***Special note on avoiding social justifications: You should not overemphasize the relevance of your experiment and the possible connections to large-scale processes. Be realistic and logical —do not overgeneralize or state grand implications that are not sensible given the structure of your experimental system. Not all science is easily applied to improving the human condition. Performing an investigation just for the sake of adding to our scientific knowledge (“pure or basic science”) is just as important as applied science. In fact, basic science often provides the foundation for applied studies.

Hypothesis / Predictions : specific prediction(s) that you will test during your experiment. For manipulative experiments, the hypothesis should include the independent variable (what you manipulate), the dependent variable(s) (what you measure), the organism or system , the direction of your results, and comparison to be made.

If you are doing a systematic observation , your hypothesis presents a variable or set of variables that you predict are important for helping you characterize the system as a whole, or predict differences between components/areas of the system that help you explain how the system functions or changes over time.

Experimental Approach : Briefly gives the reader a general sense of the experiment, the type of data it will yield, and the kind of conclusions you expect to obtain from the data. Do not confuse the experimental approach with the experimental protocol . The experimental protocol consists of the detailed step-by-step procedures and techniques used during the experiment that are to be reported in the Methods and Materials section.

Some Final Tips on Writing an Introduction

  • As you progress through the Biocore sequence, for instance, from organismal level of Biocore 301/302 to the cellular level in Biocore 303/304, we expect the contents of your “Introduction” paragraphs to reflect the level of your coursework and previous writing experience. For example, in Biocore 304 (Cell Biology Lab) biological rationale should draw upon assumptions we are making about cellular and biochemical processes.
  • Be Concise yet Specific: Remember to be concise and only include relevant information given your audience and your experimental design. As you write, keep asking, “Is this necessary information or is this irrelevant detail?” For example, if you are writing a paper claiming that a certain compound is a competitive inhibitor to the enzyme alkaline phosphatase and acts by binding to the active site, you need to explain (briefly) Michaelis-Menton kinetics and the meaning and significance of Km and Vmax. This explanation is not necessary if you are reporting the dependence of enzyme activity on pH because you do not need to measure Km and Vmax to get an estimate of enzyme activity.
  • Another example: if you are writing a paper reporting an increase in Daphnia magna heart rate upon exposure to caffeine you need not describe the reproductive cycle of magna unless it is germane to your results and discussion. Be specific and concrete, especially when making introductory or summary statements.

Where Do You Discuss Pilot Studies? Many times it is important to do pilot studies to help you get familiar with your experimental system or to improve your experimental design. If your pilot study influences your biological rationale or hypothesis, you need to describe it in your Introduction. If your pilot study simply informs the logistics or techniques, but does not influence your rationale, then the description of your pilot study belongs in the Materials and Methods section.  

How will introductions be evaluated? The following is part of the rubric we will be using to evaluate your papers.

We write different types of papers for academic and professional reasons. Research paper is one of the most important papers and it is different from other papers. There are different types of rules for writing a research paper , the first part is the introduction. Through this article, we will try to tell you how to write an introduction for a research paper beautifully.

Introduction

Before starting to write any papers, especially research papers one should know how to write a research paper introduction. The introduction is intended to guide the reader from a general subject to a specific area of study. It establishes the context of the research being conducted by summarizing current understanding and background information on the topic, stating the purpose of the work in the form of a thesis, question, or research problem, Briefly explaining your rationale, your methodological approach, highlight the potential findings your research may reveal, and describe the remaining structure of the paper.

A well-written introduction is imperative since, essentially, you never get a second chance to form a great first impression. The opening passage of your paper will give your audience their introductory impression, almost the rationale of your contention, your composing style, the general quality of your investigation, and, eventually, the legitimacy of your discoveries and conclusions. A vague, disorganized, or error-filled introduction will create a negative impression on the readers. While a brief, engaging, and well-written introduction will begin your readers off considering profoundly your expository abilities, your writing style, and your research approach. 

Tips for Writng an Introduction in Research Paper

How to Write Introduction in Research Paper

Introduce your topic

This is a significant part of how to write an introduction for a research paper. The first task of the introduction is to tell the reader what your topic is and why it is interesting or important. This is usually done with a strong opening hook.

A hook is a strong opening sentence that conveys relevance to your topic. Think of an interesting fact or statistic, a powerful statement, a question, or a brief anecdote that will make readers wonder about your topic.

Describe the context

This introduction varies depending on your approach to your writing. In a more argumentative article, you will explore the general context here. In a more empirical paper, this is a great place to review previous research and determine how your research fits together.

Start briefly, and narrow down

The first thing of a research paper introduction is, to briefly describe your broad parts of research, then narrow in on your specific focus. This will help position your research topic within a broader field, making the work accessible to a wider audience than just experts in your field.

A common mistake when writing a research paper introduction is trying to fit everything in at once. Instead, pace yourself and present each piece of information in the most logical order the reader can understand. Typically, this means starting with the big picture and then gradually getting more specific with the details.

For your research paper introduction, you should first present an overview of the topic and then focus on your specific paper. This “funnel” structure naturally includes all the necessary parts of what should be included in a research paper introduction, from context to appropriate or research gaps and finally to relevance.

State Objective and Importance

Papers abandoned because they “do not demonstrate the importance of the topic” or “lack a clear motivation” often miss this point. Say what you want to achieve and why your readers should want to know whether you achieved it or not.

Quote generously

Once you have focused on the specific topic of your research, you should detail the latest and most relevant literature related to your research. Your literature review should be comprehensive but not too long. Remember, you are not writing a review. If you find your introduction is too long or has too many citations, a possible solution is to cite journal articles, rather than cite all of the individual articles that have been summarised in the journal.

Do not Keep it broad

Try to avoid lengthy introductions. A good target is between 500 and 1,000 words, although checking the magazine’s guidelines and back issues will provide the clearest guidance.

The introduction is not lengthy or detailed; rather, they are initiating actions. Introductions are best when they get to the point: save the details in the body of the document, where they belong.

The most important point of a research paper introduction is that they are clear and easy to understand. Writing at length can be distracting and even make your point harder to understand, so cut out unnecessary words and try to express things in simple terms that everyone understands. understandable.

Check journal condition

Many journals have specific assertions in their author instructions. For example, a maximum of one word may be stated, or instructions may require specific content, such as a supposition statement or a summary of your key findings.

Write the introduction to your research paper at the last moment

Your introduction may appear first in a research paper, but the general advice is to wait to write it until everything else has been written. This makes it easier for you to summarize your article because at this point you know everything you’re going to say. This also eliminates the urge to include everything in the introduction because you don’t want to forget anything.

Additionally, it is especially helpful to write an introduction after your research paper is finished. The introduction and conclusion of a research paper have similar topics and often reflect the structure of each topic. Writing the conclusion is also generally easier thanks to the pace created by writing the rest of the paper, and the conclusion can guide you in writing the introduction.

Make your introduction narrative style

Although not always appropriate for formal writing, using a narrative style in the introduction of your research paper can do a lot to engage readers and engage them emotionally. A 2016 study found that in some articles, using narrative strategies improved how often they were cited in other articles. Narrative style involves making the paper more personal to appeal to the reader’s emotions.

  • Use first-person pronouns (I, we, my, our) to show that you are the narrator expressing emotions and feelings in the text setting up the scene. 
  • Describe the times and locations of important events to help readers visualize them. 
  • Appeal to the reader’s morality, sympathy, or urgency as a persuasive tactic. Again, this style will not be appropriate for all research paper introductions, especially those devoted to scientific research. 

However, for more informal research papers and especially essays, this style can make your writing more interesting or at least interesting, perfect for making readers excited right from the beginning of the article.

Use the CARS model

British scientist John Swales developed a method called the CARS model to “generate a search space” in the introduction. Although intended for scientific papers, this simple three-step structure can be used to outline the introduction to any research paper.

Explain the background of your topic, including previous research. Explain that information is lacking in your topic area or that current research is incomplete.

Explain how your research “fills in” missing information about your topic. 

the research findings and providing an overview of the structure of the rest of the paper, although this does not apply to all research papers, especially those Unofficial documents.

Six Essential Elements of How to Write a Research Paper Introduction

1. topic overview.

Start with a general overview of your topic. Refine your outline until you address the specific topic of your article. Next, mention any questions or concerns you have about the case. Note that you will address these in the article.

2. Previous research

Your introduction is the perfect place to review other findings about your topic. Includes both old and modern scholars. This general information shows that you are aware of previous research. It also presents previous findings to those who may not have that expertise.

3. A justification for your article

Explain why your topic needs to be discussed now. If possible, connect it to current issues. Additionally, you can point out problems with old theories or reveal gaps in current research. No matter how you do it, a good reason will keep readers interested and demonstrate why they should read the rest of your article.

4. Describe the method you used

Tell about your processes to make your writing more trustworthy. Identify your goals and the questions you will answer. Reveal how you conducted the research and describe how you measured the results. Also, explain why you made the important choices.

5. A thesis statement

Your main introduction should end with a thesis statement. This statement summarises the ideas that will run throughout your entire research paper. It must be simple and clear.

6. An outline

It is an adequate idea of how to write an introduction for a research paper. 

The introduction usually ends with an overview. Your layout should quickly present what you plan to cover in the following sections. Think of it as a road map, guiding readers to the end of your article.

What is the purpose of the introduction in a research paper, and why is it considered crucial?

The purpose of the introduction in a research paper is to guide the reader from a general subject to a specific area of study. It establishes the context of the research by summarizing current understanding, stating the purpose of the work, explaining the rationale and methodological approach, highlighting potential findings, and describing the paper’s structure. It’s considered crucial because it forms the reader’s first impression and sets the tone for the rest of the paper.

How can I effectively use a hook to engage readers in my research paper introduction?

Using a hook, such as an interesting fact, a powerful statement, a question, or a brief anecdote, can effectively engage readers in your research paper introduction. A hook captures the reader’s attention and makes them curious about your topic, encouraging them to continue reading.

How long the introduction should be in a research paper?

While there’s no strict word count, a good target for a research paper introduction is between 500 and 1,000 words, although you should check the specific guidelines provided by the journal you’re submitting to. It’s recommended to write the introduction after the rest of the paper has been completed. This way, you have a comprehensive understanding of your research, making it easier to summarize and guide your readers effectively.

Conclusion 

These are the important tips and tricks on how to write an introduction for a research paper properly. If you maintain these rules we believe that you will be able to write an excellent introduction in your research paper.

How to Write a Research Introduction

Last Updated: December 6, 2023 Fact Checked

This article was co-authored by Megan Morgan, PhD . Megan Morgan is a Graduate Program Academic Advisor in the School of Public & International Affairs at the University of Georgia. She earned her PhD in English from the University of Georgia in 2015. There are 7 references cited in this article, which can be found at the bottom of the page. This article has been fact-checked, ensuring the accuracy of any cited facts and confirming the authority of its sources. This article has been viewed 2,653,710 times.

The introduction to a research paper can be the most challenging part of the paper to write. The length of the introduction will vary depending on the type of research paper you are writing. An introduction should announce your topic, provide context and a rationale for your work, before stating your research questions and hypothesis. Well-written introductions set the tone for the paper, catch the reader's interest, and communicate the hypothesis or thesis statement.

Introducing the Topic of the Paper

Step 1 Announce your research topic.

  • In scientific papers this is sometimes known as an "inverted triangle", where you start with the broadest material at the start, before zooming in on the specifics. [2] X Research source
  • The sentence "Throughout the 20th century, our views of life on other planets have drastically changed" introduces a topic, but does so in broad terms.
  • It provides the reader with an indication of the content of the essay and encourages them to read on.

Step 2 Consider referring to key words.

  • For example, if you were writing a paper about the behaviour of mice when exposed to a particular substance, you would include the word "mice", and the scientific name of the relevant compound in the first sentences.
  • If you were writing a history paper about the impact of the First World War on gender relations in Britain, you should mention those key words in your first few lines.

Step 3 Define any key terms or concepts.

  • This is especially important if you are attempting to develop a new conceptualization that uses language and terminology your readers may be unfamiliar with.

Step 4 Introduce the topic through an anecdote or quotation.

  • If you use an anecdote ensure that is short and highly relevant for your research. It has to function in the same way as an alternative opening, namely to announce the topic of your research paper to your reader.
  • For example, if you were writing a sociology paper about re-offending rates among young offenders, you could include a brief story of one person whose story reflects and introduces your topic.
  • This kind of approach is generally not appropriate for the introduction to a natural or physical sciences research paper where the writing conventions are different.

Establishing the Context for Your Paper

Step 1 Include a brief literature review.

  • It is important to be concise in the introduction, so provide an overview on recent developments in the primary research rather than a lengthy discussion.
  • You can follow the "inverted triangle" principle to focus in from the broader themes to those to which you are making a direct contribution with your paper.
  • A strong literature review presents important background information to your own research and indicates the importance of the field.

Step 2 Use the literature to focus in on your contribution.

  • By making clear reference to existing work you can demonstrate explicitly the specific contribution you are making to move the field forward.
  • You can identify a gap in the existing scholarship and explain how you are addressing it and moving understanding forward.

Step 3 Elaborate on the rationale of your paper.

  • For example, if you are writing a scientific paper you could stress the merits of the experimental approach or models you have used.
  • Stress what is novel in your research and the significance of your new approach, but don't give too much detail in the introduction.
  • A stated rationale could be something like: "the study evaluates the previously unknown anti-inflammatory effects of a topical compound in order to evaluate its potential clinical uses".

Specifying Your Research Questions and Hypothesis

Step 1 State your research questions.

  • The research question or questions generally come towards the end of the introduction, and should be concise and closely focused.
  • The research question might recall some of the key words established in the first few sentences and the title of your paper.
  • An example of a research question could be "what were the consequences of the North American Free Trade Agreement on the Mexican export economy?"
  • This could be honed further to be specific by referring to a particular element of the Free Trade Agreement and the impact on a particular industry in Mexico, such as clothing manufacture.
  • A good research question should shape a problem into a testable hypothesis.

Step 2 Indicate your hypothesis.

  • If possible try to avoid using the word "hypothesis" and rather make this implicit in your writing. This can make your writing appear less formulaic.
  • In a scientific paper, giving a clear one-sentence overview of your results and their relation to your hypothesis makes the information clear and accessible. [10] X Trustworthy Source PubMed Central Journal archive from the U.S. National Institutes of Health Go to source
  • An example of a hypothesis could be "mice deprived of food for the duration of the study were expected to become more lethargic than those fed normally".

Step 3 Outline the structure of your paper.

  • This is not always necessary and you should pay attention to the writing conventions in your discipline.
  • In a natural sciences paper, for example, there is a fairly rigid structure which you will be following.
  • A humanities or social science paper will most likely present more opportunities to deviate in how you structure your paper.

How to Write an Introduction for a Research Paper

Academic Writing Service

How to write an introduction for a research paper? Eventually (and with practice) all writers will develop their own strategy for writing the perfect introduction for a research paper. Once you are comfortable with writing, you will probably find your own, but coming up with a good strategy can be tough for beginning writers.

The Purpose of an Introduction

Your opening paragraphs, phrases for introducing thesis statements, research paper introduction examples, using the introduction to map out your research paper.

  • First write your thesis.Your thesis should state the main idea in specific terms.
  • After you have a working thesis, tackle the body of your paper before you write the rest of the introduction. Each paragraph in the body should explore one specific topic that proves, or summarizes your thesis. Writing is a thinking process. Once you have worked your way through that process by writing the body of the paper, you will have an intimate understanding of how you are supporting your thesis. After you have written the body paragraphs, go back and rewrite your thesis to make it more specific and to connect it to the topics you addressed in the body paragraph.
  • Revise your introduction several times, saving each revision. Be sure your introduction previews the topics you are presenting in your paper. One way of doing this is to use keywords from the topic sentences in each paragraph to introduce, or preview, the topics in your introduction.This “preview” will give your reader a context for understanding how you will make your case.
  • Experiment by taking different approaches to your thesis with every revision you make. Play with the language in the introduction. Strike a new tone. Go back and compare versions. Then pick the one that works most effectively with the body of your research paper.
  • Do not try to pack everything you want to say into your introduction. Just as your introduction should not be too short, it should also not be too long. Your introduction should be about the same length as any other paragraph in your research paper. Let the content—what you have to say—dictate the length.

The first page of your research paper should draw the reader into the text. It is the paper’s most important page and, alas, often the worst written. There are two culprits here and effective ways to cope with both of them.

First, the writer is usually straining too hard to say something terribly BIG and IMPORTANT about the thesis topic. The goal is worthy, but the aim is unrealistically high. The result is often a muddle of vague platitudes rather than a crisp, compelling introduction to the thesis. Want a familiar example? Listen to most graduation speakers. Their goal couldn’t be loftier: to say what education means and to tell an entire football stadium how to live the rest of their lives. The results are usually an avalanche of clichés and sodden prose.

The second culprit is bad timing. The opening and concluding paragraphs are usually written late in the game, after the rest of the thesis is finished and polished. There’s nothing wrong with writing these sections last. It’s usually the right approach since you need to know exactly what you are saying in the substantive middle sections of the thesis before you can introduce them effectively or draw together your findings. But having waited to write the opening and closing sections, you need to review and edit them several times to catch up. Otherwise, you’ll putting the most jagged prose in the most tender spots. Edit and polish your opening paragraphs with extra care. They should draw readers into the paper.

After you’ve done some extra polishing, I suggest a simple test for the introductory section. As an experiment, chop off the first few paragraphs. Let the paper begin on, say, paragraph 2 or even page 2. If you don’t lose much, or actually gain in clarity and pace, then you’ve got a problem.

There are two solutions. One is to start at this new spot, further into the text. After all, that’s where you finally gain traction on your subject. That works best in some cases, and we occasionally suggest it. The alternative, of course, is to write a new opening that doesn’t flop around, saying nothing.

What makes a good opening? Actually, they come in several flavors. One is an intriguing story about your topic. Another is a brief, compelling quote. When you run across them during your reading, set them aside for later use. Don’t be deterred from using them because they “don’t seem academic enough.” They’re fine as long as the rest of the paper doesn’t sound like you did your research in People magazine. The third, and most common, way to begin is by stating your main questions, followed by a brief comment about why they matter.

Whichever opening you choose, it should engage your readers and coax them to continue. Having done that, you should give them a general overview of the project—the main issues you will cover, the material you will use, and your thesis statement (that is, your basic approach to the topic). Finally, at the end of the introductory section, give your readers a brief road map, showing how the paper will unfold. How you do that depends on your topic but here are some general suggestions for phrase choice that may help:

  • This analysis will provide …
  • This paper analyzes the relationship between …
  • This paper presents an analysis of …
  • This paper will argue that …
  • This topic supports the argument that…
  • Research supports the opinion that …
  • This paper supports the opinion that …
  • An interpretation of the facts indicates …
  • The results of this experiment show …
  • The results of this research show …

Comparisons/Contrasts

  • A comparison will show that …
  • By contrasting the results,we see that …
  • This paper examines the advantages and disadvantages of …

Definitions/Classifications

  • This paper will provide a guide for categorizing the following:…
  • This paper provides a definition of …
  • This paper explores the meaning of …
  • This paper will discuss the implications of …
  • A discussion of this topic reveals …
  • The following discussion will focus on …

Description

  • This report describes…
  • This report will illustrate…
  • This paper provides an illustration of …

Process/Experimentation

  • This paper will identify the reasons behind…
  • The results of the experiment show …
  • The process revealed that …
  • This paper theorizes…
  • This paper presents the theory that …
  • In theory, this indicates that …

Quotes, anecdotes, questions, examples, and broad statements—all of them can used successfully to write an introduction for a research paper. It’s instructive to see them in action, in the hands of skilled academic writers.

Let’s begin with David M. Kennedy’s superb history, Freedom from Fear: The American People in Depression and War, 1929–1945 . Kennedy begins each chapter with a quote, followed by his text. The quote above chapter 1 shows President Hoover speaking in 1928 about America’s golden future. The text below it begins with the stock market collapse of 1929. It is a riveting account of just how wrong Hoover was. The text about the Depression is stronger because it contrasts so starkly with the optimistic quotation.

“We in America today are nearer the final triumph over poverty than ever before in the history of any land.”—Herbert Hoover, August 11, 1928 Like an earthquake, the stock market crash of October 1929 cracked startlingly across the United States, the herald of a crisis that was to shake the American way of life to its foundations. The events of the ensuing decade opened a fissure across the landscape of American history no less gaping than that opened by the volley on Lexington Common in April 1775 or by the bombardment of Sumter on another April four score and six years later. The ratcheting ticker machines in the autumn of 1929 did not merely record avalanching stock prices. In time they came also to symbolize the end of an era. (David M. Kennedy, Freedom from Fear: The American People in Depression and War, 1929–1945 . New York: Oxford University Press, 1999, p. 10)

Kennedy has exciting, wrenching material to work with. John Mueller faces the exact opposite problem. In Retreat from Doomsday: The Obsolescence of Major War , he is trying to explain why Great Powers have suddenly stopped fighting each other. For centuries they made war on each other with devastating regularity, killing millions in the process. But now, Mueller thinks, they have not just paused; they have stopped permanently. He is literally trying to explain why “nothing is happening now.” That may be an exciting topic intellectually, it may have great practical significance, but “nothing happened” is not a very promising subject for an exciting opening paragraph. Mueller manages to make it exciting and, at the same time, shows why it matters so much. Here’s his opening, aptly entitled “History’s Greatest Nonevent”:

On May 15, 1984, the major countries of the developed world had managed to remain at peace with each other for the longest continuous stretch of time since the days of the Roman Empire. If a significant battle in a war had been fought on that day, the press would have bristled with it. As usual, however, a landmark crossing in the history of peace caused no stir: the most prominent story in the New York Times that day concerned the saga of a manicurist, a machinist, and a cleaning woman who had just won a big Lotto contest. This book seeks to develop an explanation for what is probably the greatest nonevent in human history. (John Mueller, Retreat from Doomsday: The Obsolescence of Major War . New York: Basic Books, 1989, p. 3)

In the space of a few sentences, Mueller sets up his puzzle and reveals its profound human significance. At the same time, he shows just how easy it is to miss this milestone in the buzz of daily events. Notice how concretely he does that. He doesn’t just say that the New York Times ignored this record setting peace. He offers telling details about what they covered instead: “a manicurist, a machinist, and a cleaning woman who had just won a big Lotto contest.” Likewise, David Kennedy immediately entangles us in concrete events: the stunning stock market crash of 1929. These are powerful openings that capture readers’ interests, establish puzzles, and launch narratives.

Sociologist James Coleman begins in a completely different way, by posing the basic questions he will study. His ambitious book, Foundations of Social Theory , develops a comprehensive theory of social life, so it is entirely appropriate for him to begin with some major questions. But he could just as easily have begun with a compelling story or anecdote. He includes many of them elsewhere in his book. His choice for the opening, though, is to state his major themes plainly and frame them as a paradox. Sociologists, he says, are interested in aggregate behavior—how people act in groups, organizations, or large numbers—yet they mostly examine individuals:

A central problem in social science is that of accounting for the function of some kind of social system. Yet in most social research, observations are not made on the system as a whole, but on some part of it. In fact, the natural unit of observation is the individual person…  This has led to a widening gap between theory and research… (James S. Coleman, Foundations of Social Theory . Cambridge, MA: Harvard University Press, 1990, pp. 1–2)

After expanding on this point, Coleman explains that he will not try to remedy the problem by looking solely at groups or aggregate-level data. That’s a false solution, he says, because aggregates don’t act; individuals do. So the real problem is to show the links between individual actions and aggregate outcomes, between the micro and the macro.

The major problem for explanations of system behavior based on actions and orientations at a level below that of the system [in this case, on individual-level actions] is that of moving from the lower level to the system level. This has been called the micro-to-macro problem, and it is pervasive throughout the social sciences. (Coleman, Foundations of Social Theory , p. 6)

Explaining how to deal with this “micro-to-macro problem” is the central issue of Coleman’s book, and he announces it at the beginning.

Coleman’s theory-driven opening stands at the opposite end of the spectrum from engaging stories or anecdotes, which are designed to lure the reader into the narrative and ease the path to a more analytic treatment later in the text. Take, for example, the opening sentences of Robert L. Herbert’s sweeping study Impressionism: Art, Leisure, and Parisian Society : “When Henry Tuckerman came to Paris in 1867, one of the thousands of Americans attracted there by the huge international exposition, he was bowled over by the extraordinary changes since his previous visit twenty years before.” (Robert L. Herbert, Impressionism: Art, Leisure, and Parisian Society . New Haven, CT: Yale University Press, 1988, p. 1.) Herbert fills in the evocative details to set the stage for his analysis of the emerging Impressionist art movement and its connection to Parisian society and leisure in this period.

David Bromwich writes about Wordsworth, a poet so familiar to students of English literature that it is hard to see him afresh, before his great achievements, when he was just a young outsider starting to write. To draw us into Wordsworth’s early work, Bromwich wants us to set aside our entrenched images of the famous mature poet and see him as he was in the 1790s, as a beginning writer on the margins of society. He accomplishes this ambitious task in the opening sentences of Disowned by Memory: Wordsworth’s Poetry of the 1790s :

Wordsworth turned to poetry after the revolution to remind himself that he was still a human being. It was a curious solution, to a difficulty many would not have felt. The whole interest of his predicament is that he did feel it. Yet Wordsworth is now so established an eminence—his name so firmly fixed with readers as a moralist of self-trust emanating from complete self-security—that it may seem perverse to imagine him as a criminal seeking expiation. Still, that is a picture we get from The Borderers and, at a longer distance, from “Tintern Abbey.” (David Bromwich, Disowned by Memory: Wordsworth’s Poetry of the 1790s . Chicago: University of Chicago Press, 1998, p. 1)

That’s a wonderful opening! Look at how much Bromwich accomplishes in just a few words. He not only prepares the way for analyzing Wordsworth’s early poetry; he juxtaposes the anguished young man who wrote it to the self-confident, distinguished figure he became—the eminent man we can’t help remembering as we read his early poetry.

Let us highlight a couple of other points in this passage because they illustrate some intelligent writing choices. First, look at the odd comma in this sentence: “It was a curious solution, to a difficulty many would not have felt.” Any standard grammar book would say that comma is wrong and should be omitted. Why did Bromwich insert it? Because he’s a fine writer, thinking of his sentence rhythm and the point he wants to make. The comma does exactly what it should. It makes us pause, breaking the sentence into two parts, each with an interesting point. One is that Wordsworth felt a difficulty others would not have; the other is that he solved it in a distinctive way. It would be easy for readers to glide over this double message, so Bromwich has inserted a speed bump to slow us down. Most of the time, you should follow grammatical rules, like those about commas, but you should bend them when it serves a good purpose. That’s what the writer does here.

The second small point is the phrase “after the revolution” in the first sentence: “Wordsworth turned to poetry after the revolution to remind himself that he was still a human being.” Why doesn’t Bromwich say “after the French Revolution”? Because he has judged his book’s audience. He is writing for specialists who already know which revolution is reverberating through English life in the 1790s. It is the French Revolution, not the earlier loss of the American colonies. If Bromwich were writing for a much broader audience—say, the New York Times Book Review—he would probably insert the extra word to avoid confusion.

The message “Know your audience” applies to all writers. Don’t talk down to them by assuming they can’t get dressed in the morning. Don’t strut around showing off your book learnin’ by tossing in arcane facts and esoteric language for its own sake. Neither will win over readers.

Bromwich, Herbert, and Coleman open their works in different ways, but their choices work well for their different texts. Your task is to decide what kind of opening will work best for yours. Don’t let that happen by default, by grabbing the first idea you happen upon. Consider a couple of different ways of opening your thesis and then choose the one you prefer. Give yourself some options, think them over, then make an informed choice.

Whether you begin with a story, puzzle, or broad statement, the next part of the introduction should pose your main questions and establish your argument. This is your thesis statement—your viewpoint along with the supporting reasons and evidence. It should be articulated plainly so readers understand full well what your paper is about and what it will argue.

After that, give your readers a road map of what’s to come. That’s normally done at the end of the introductory section (or, in a book, at the end of the introductory chapter). Here’s John J. Mearsheimer presenting such a road map in The Tragedy of Great Power Politics . He not only tells us the order of upcoming chapters, he explains why he’s chosen that order and which chapters are most important:

The Plan of the Book The rest of the chapters in this book are concerned mainly with answering the six big questions about power which I identified earlier. Chapter 2, which is probably the most important chapter in the book, lays out my theory of why states compete for power and why they pursue hegemony. In Chapters 3 and 4, I define power and explain how to measure it. I do this in order to lay the groundwork for testing my theory… (John J. Mearsheimer, The Tragedy of Great Power Politics . New York: W. W. Norton, 2001, p. 27)

As this excerpt makes clear, Mearsheimer has already laid out his “six big questions” in the introduction. Now he’s showing us the path ahead, the path to answering those questions.

At the end of the introduction, give your readers a road map of what’s to come. Tell them what the upcoming sections will be and why they are arranged in this particular order.

After having written your introduction it’s time to move to the biggest part: body of a research paper.

How to Write an Introduction For a Research Paper

Learn how to write a strong and efficient research paper introduction by following the suitable structure and avoiding typical errors.

' src=

An introduction to any type of paper is sometimes misunderstood as the beginning; yet, an introduction is actually intended to present your chosen subject to the audience in a way that makes it more appealing and leaves your readers thirsty for more information. After the title and abstract, your audience will read the introduction, thus it’s critical to get off to a solid start.  

This article includes instructions on how to write an introduction for a research paper that engages the reader in your research. You can produce a strong opening for your research paper if you stick to the format and a few basic principles.

What is An Introduction To a Research Paper?

An introduction is the opening section of a research paper and the section that a reader is likely to read first, in which the objective and goals of the subsequent writing are stated. 

The introduction serves numerous purposes. It provides context for your research, explains your topic and objectives, and provides an outline of the work. A solid introduction will establish the tone for the remainder of your paper, enticing readers to continue reading through the methodology, findings, and discussion. 

Even though introductions are generally presented at the beginning of a document, we must distinguish an introduction from the beginning of your research. An introduction, as the name implies, is supposed to introduce your subject without extending it. All relevant information and facts should be placed in the body and conclusion, not the introduction.

Structure Of An Introduction

Before explaining how to write an introduction for a research paper , it’s necessary to comprehend a structure that will make your introduction stronger and more straightforward.

A Good Hook

A hook is one of the most effective research introduction openers. A hook’s objective is to stimulate the reader’s interest to read the research paper.  There are various approaches you may take to generate a strong hook:  startling facts, a question, a brief overview, or even a quotation. 

Broad Overview

Following an excellent hook, you should present a wide overview of your major issue and some background information on your research. If you’re unsure about how to begin an essay introduction, the best approach is to offer a basic explanation of your topic before delving into specific issues. Simply said, you should begin with general information and then narrow it down to your relevant topics.

After offering some background information regarding your research’s main topic, go on to give readers a better understanding of what you’ll be covering throughout your research. In this section of your introduction, you should swiftly clarify your important topics in the sequence in which they will be addressed later, gradually introducing your thesis statement. You can use some  The following are some critical questions to address in this section of your introduction: Who? What? Where? When? How? And why is that?

Thesis Statement

The thesis statement, which must be stated in the beginning clause of your research since your entire research revolves around it, is the most important component of your research.

A thesis statement presents your audience with a quick overview of the research’s main assertion. In the body section of your work, your key argument is what you will expose or debate about it. An excellent thesis statement is usually very succinct, accurate, explicit, clear, and focused. Typically, your thesis should be at the conclusion of your introductory paragraph/section.

Tips for Writing a Strong Introduction

Aside from the good structure, here are a few tips to make your introduction strong and accurate:

  • Keep in mind the aim of your research and make sure your introduction supports it.
  • Use an appealing and relevant hook that catches the reader’s attention right away.
  • Make it obvious to your readers what your stance is.
  • Demonstrate your knowledge of your subject.
  • Provide your readers with a road map to help them understand what you will address throughout the research.
  • Be succinct – it is advised that your opening introduction consists of around 8-9 percent of the overall amount of words in your article (for example, 160 words for a 2000 words essay). 
  • Make a strong and unambiguous thesis statement.
  • Explain why the article is significant in 1-2 sentences.
  • Remember to keep it interesting.

Mistakes to Avoid in Your Introduction

Check out what not to do and what to avoid now that you know the structure and how to write an introduction for a research paper .

  • Lacking a feeling of direction or purpose.
  • Giving out too much.
  • Creating lengthy paragraphs.
  • Excessive or insufficient background, literature, and theory.
  • Including material that should be placed in the body and conclusion.
  • Not writing enough or writing excessively.
  • Using too many quotes.

An Introduction to a scientific paper familiarizes the reader with the background of the issue at hand. It must reflect why the issue is topical and its current importance in the vast sea of research being done globally. It lays the foundation of biomedical writing and is the first portion of an article according to the IMRAD pattern ( I ntroduction, M ethodology, R esults, a nd D iscussion) [1].

I once had a professor tell a class that he sifted through our pile of essays, glancing at the titles and introductions, looking for something that grabbed his attention. Everything else went to the bottom of the pile to be read last, when he was tired and probably grumpy from all the marking. Don’t get put at the bottom of the pile, he said. Anonymous

An Introduction to a scientific paper familiarizes the reader with the background of the issue at hand. It must reflect why the issue is topical and its current importance in the vast sea of research being done globally. It lays the foundation of biomedical writing and is the first portion of an article according to the IMRAD pattern ( I ntroduction, M ethodology, R esults, a nd D iscussion) [ 1 ].

It provides the flavour of the article and many authors have used phrases to describe it for example—'like a gate of the city’ [ 2 ], ‘the beginning is half of the whole’ [ 3 ], ‘an introduction is not just wrestling with words to fit the facts, but it also strongly modulated by perception of the anticipated reactions of peer colleagues’, [ 4 ] and ‘an introduction is like the trailer to a movie’. A good introduction helps captivate the reader early.

figure a

2 What Are the Principles of Writing a Good Introduction?

A good introduction will ‘sell’ an article to a journal editor, reviewer, and finally to a reader [ 3 ]. It should contain the following information [ 5 , 6 ]:

The known—The background scientific data

The unknown—Gaps in the current knowledge

Research hypothesis or question

Methodologies used for the study

The known consist of citations from a review of the literature whereas the unknown is the new work to be undertaken. This part should address how your work is the required missing piece of the puzzle.

3 What Are the Models of Writing an Introduction?

The Problem-solving model

First described by Swales et al. in 1979, in this model the writer should identify the ‘problem’ in the research, address the ‘solution’ and also write about ‘the criteria for evaluating the problem’ [ 7 , 8 ].

The CARS model that stands for C reating A R esearch S pace [ 9 , 10 ].

The two important components of this model are:

Establishing a territory (situation)

Establishing a niche (problem)

Occupying a niche (the solution)

In this popular model, one can add a fourth point, i.e., a conclusion [ 10 ].

4 What Is Establishing a Territory?

This includes: [ 9 ]

Stating the general topic and providing some background about it.

Providing a brief and relevant review of the literature related to the topic.

Adding a paragraph on the scope of the topic including the need for your study.

5 What Is Establishing a Niche?

Establishing a niche includes:

Stating the importance of the problem.

Outlining the current situation regarding the problem citing both global and national data.

Evaluating the current situation (advantages/ disadvantages).

Identifying the gaps.

Emphasizing the importance of the proposed research and how the gaps will be addressed.

Stating the research problem/ questions.

Stating the hypotheses briefly.

Figure 17.1 depicts how the introduction needs to be written. A scientific paper should have an introduction in the form of an inverted pyramid. The writer should start with the general information about the topic and subsequently narrow it down to the specific topic-related introduction.

figure 1

Flow of ideas from the general to the specific

6 What Does Occupying a Niche Mean?

This is the third portion of the introduction and defines the rationale of the research and states the research question. If this is missing the reviewers will not understand the logic for publication and is a common reason for rejection [ 11 , 12 ]. An example of this is given below:

Till date, no study has been done to see the effectiveness of a mesh alone or the effectiveness of double suturing along with a mesh in the closure of an umbilical hernia regarding the incidence of failure. So, the present study is aimed at comparing the effectiveness of a mesh alone versus the double suturing technique along with a mesh.

7 How Long Should the Introduction Be?

For a project protocol, the introduction should be about 1–2 pages long and for a thesis it should be 3–5 pages in a double-spaced typed setting. For a scientific paper it should be less than 10–15% of the total length of the manuscript [ 13 , 14 ].

8 How Many References Should an Introduction Have?

All sections in a scientific manuscript except the conclusion should contain references. It has been suggested that an introduction should have four or five or at the most one-third of the references in the whole paper [ 15 ].

9 What Are the Important Points Which Should be not Missed in an Introduction?

An introduction paves the way forward for the subsequent sections of the article. Frequently well-planned studies are rejected by journals during review because of the simple reason that the authors failed to clarify the data in this section to justify the study [ 16 , 17 ]. Thus, the existing gap in knowledge should be clearly brought out in this section (Fig. 17.2 ).

figure 2

How should the abstract, introduction, and discussion look

The following points are important to consider:

The introduction should be written in simple sentences and in the present tense.

Many of the terms will be introduced in this section for the first time and these will require abbreviations to be used later.

The references in this section should be to papers published in quality journals (e.g., having a high impact factor).

The aims, problems, and hypotheses should be clearly mentioned.

Start with a generalization on the topic and go on to specific information relevant to your research.

10 Example of an Introduction

figure b

11 Conclusions

An Introduction is a brief account of what the study is about. It should be short, crisp, and complete.

It has to move from a general to a specific research topic and must include the need for the present study.

The Introduction should include data from a literature search, i.e., what is already known about this subject and progress to what we hope to add to this knowledge.

How to Introduce Evidence: 41 Effective Phrases & Examples

what to put in the introduction of a research paper

Research requires us to scrutinize information and assess its credibility. Accordingly, when we think about various phenomena, we examine empirical data and craft detailed explanations justifying our interpretations. An essential component of constructing our research narratives is thus providing supporting evidence and examples.

The type of proof we provide can either bolster our claims or leave readers confused or skeptical of our analysis. Therefore, it’s crucial that we use appropriate, logical phrases that guide readers clearly from one idea to the next. In this article, we explain how evidence and examples should be introduced according to different contexts in academic writing and catalog effective language you can use to support your arguments, examples included.

When to Introduce Evidence and Examples in a Paper

Evidence and examples create the foundation upon which your claims can stand firm. Without proof, your arguments lack credibility and teeth. However, laundry listing evidence is as bad as failing to provide any materials or information that can substantiate your conclusions. Therefore, when you introduce examples, make sure to judiciously provide evidence when needed and use phrases that will appropriately and clearly explain how the proof supports your argument.

There are different types of claims and different types of evidence in writing. You should introduce and link your arguments to evidence when you

  • state information that is not “common knowledge”;
  • draw conclusions, make inferences, or suggest implications based on specific data;
  • need to clarify a prior statement, and it would be more effectively done with an illustration;
  • need to identify representative examples of a category;
  • desire to distinguish concepts; and
  • emphasize a point by highlighting a specific situation.

Introductory Phrases to Use and Their Contexts

To assist you with effectively supporting your statements, we have organized the introductory phrases below according to their function. This list is not exhaustive but will provide you with ideas of the types of phrases you can use.

Although any research author can make use of these helpful phrases and bolster their academic writing by entering them into their work, before submitting to a journal, it is a good idea to let a professional English editing service take a look to ensure that all terms and phrases make sense in the given research context. Wordvice offers paper editing , thesis editing , and dissertation editing services that help elevate your academic language and make your writing more compelling to journal authors and researchers alike.

A research paper is an academic work depicting the design and results of a study. It can be an academic assignment in undergraduate and postgraduate programs. Moreover, it is an integral requirement in doctoral programs, where postgrads’ research papers are published in reputable journals to add credibility to their research findings. 

Ordering different parts of a research paper is critical for fulfilling academic standards, streamlining your writing, and avoiding distractions and sidetracks. Although outlining may seem like a waste of time, it is the most efficient use of your time at the pre-writing stage, as it will help you order your thoughts and ideas and develop a plan of action to follow throughout the study. 

In this post, we’ll cover the basics of the research paper formatting, provide a basic template of a research paper structure, and provide a detailed description of each section, including the title page and abstract, introduction and literature review, methodology, results, discussion, and conclusion. You can skip to a specific section if you have questions or concerns about it or check out the full article for an in-depth understanding of the full structure. 

Essential Components of a Research Paper

Unlike other types of academic assignments, research papers have a structure more complex than a simple trio of introduction, body, and conclusion. You are expected to follow the established academic norms and include specific information for your paper to have any scientific value. The basic research paper structure example comprises the following parts:

Introduction

  • Literature review

Methodology

  • Acknowledgments

Please note that some sections of a research paper outlined above are optional. For example, you only need to include appendices if you wish to share a large volume of data that would make the paper unwieldy. You can also adjust this research paper setup to fit your study and word count requirements better. For instance, you can combine the results and discussion sections or the introduction and literature review.

Formatting Requirements

Although the research paper structure is basically the same for all fields of study and topics, the papers can look drastically different when following research paper formatting guidelines of various formatting styles, be it Chicago, MLA, or APA. You must learn the appropriate style at the onset of the writing process, so remember to ask your academic advisor about it if there’s no mention of the formatting style within general requirements.

Once you know which research paper formatting style to use, get your hands on the relevant formatting guidebook. You can find most of the requirements online or sign out a book from a college library. Considering most formatting guidebooks are huge, focus on the main aspects that can make or break your paper, such as:

  • Margins, font, and spacing. Most research paper format guidelines require 1-inch margins on all sides, a legible font of at least 12 pt, and double-spaced lines. 
  • Page numbering. Requirements vary, but typically, you’ll need to include page numbers in the upper right-hand corner, half an inch from the corner.
  • Headings and subheadings. Refer to MLA or APA handbooks to learn specific research paper headings requirements or ask your professor, as the guidelines differ greatly. 
  • In-text citations and reference list. In most cases, research paper in-text citations require the name of the main author along with the page number or the publication year. Reference list formatting varies across different styles, but you can use automatic citation generators to speed up the formatting process.

With formatting requirements out of the way, let’s now focus on individual components of a research paper to help you understand what each section should contain to be well received.

Title Page and Abstract

The research paper title page format depends on the required formatting style:

  • MLA does not require a separate title page (unless specifically requested). Instead, in the upper left-hand corner of the first page, type your name, your instructor’s name, course name, and date (each on a new line, double-spaced). After that, center the title of the page and include its text.
  • APA requires a separate title page, which should include the title of the paper, your name and affiliation, as well as the course name and number, your instructor’s name, and the assignment’s due date. 

A research paper abstract is brief summary of the main points of the research paper. Depending on the formatting style, it can be from 100 to 250 words long, highlighting the research objective, key methodology, and results highlights. An abstract should help readers decide if your work is worth reading at a glance. 

An APA research paper organization requires an abstract on a separate page, with the “Abstract” heading and the paper’s summary (without indent). Below the abstract, type “Keywords:” (in italics) and list the keywords researchers would use to find your paper in the library or online. 

The opening section of the research paper outline gives students pause because they never know what the introduction should entail. If you’re stuck with writer’s block and don’t know how to start the paper, answer these four questions, and you’ll have all the major pieces necessary for the introduction:

  • What’s the context of the problem? Open with a general view of the issue and its current state without going into too much detail (that’s what the literature review is for). The background information should fit within one or two paragraphs and lead directly to the next point. 
  • What is the issue? The problem statement or question is the core of this part of the research paper structure. Think of it as a thesis statement for an essay. Everything you write in other sections of a research paper should always tie to your problem statement.
  • How do you plan to solve the problem? You can formulate research objectives or hypotheses that your study will try to achieve or prove. Short papers typically have one hypothesis, while longer works usually have two or more related objectives.
  • How will your study improve the issue? The answer can circle back to the background you laid out at the beginning of the research paper introduction and highlight the benefits (and potential drawbacks and limitations) of your research. It’s the major “selling point” of the study, which should explain why anyone should care about it. 

You can always leave the introduction for last and tackle it once the rest of the paper is done. That’s especially helpful if you use writer’s block as an excuse to procrastinate and put off writing other parts of a research paper.

Literature Review

The primary objective of a research paper literature review is to provide context and prove the relevance of your topic, as specified in the introduction. To that end, you need to find credible, objective, and relevant sources and synthesize any data pertaining to your research. It’s important to avoid simple paraphrasing or summarization of reference data and instead provide its analysis and synthesize your own hypothesis.

Aside from the similarities found in references, this part of the research paper structure should also focus on discrepancies, contradictions, and knowledge gaps. These will prove your study has merit and can resolve the existing issues. Moreover, the knowledge gaps will help lead up to your main research question, which you may repeat near the end of the literature review.

Depending on the topic of your study, you can organize the literature review:

  • Chronologically. You can go from the oldest sources published to the latest or from the latest events to situations long past. This approach is often the easiest, but it doesn’t fit all topics and fields of study.
  • Thematically. If you wish to cover two or more aspects of the issue, you can dedicate a subsection to each and analyze them together in the final subsection of the literature review. This is the most popular approach, as it can work for most topics.
  • Methodologically. If you want to focus on the differences and similarities in research methodology, you can split the literature review into several subsections, devoting each one to a single methodology. This approach works for select subjects and can make the most of systemic studies. 

If you’re working on an empirical study, you can stop there, but if your work is mostly theoretical, this stage of the research paper writing process could also involve developing a theoretical framework. It will help put your findings and results into perspective.

Although it may seem simple at first glance, a literature review takes a long time, most of which you’ll spend looking for reliable sources. Luckily, you can easily outsource this task. All you need to do is say, “Write my paper for me”, and our experts will take over ASAP. 

The research paper methodology section is an integral part of the piece, as it helps ensure the reproducibility of your results and increases your credibility. This part should answer two main questions:

  • What? What did your study involve? What resources, software, materials, or samples did you use? What were the ethical considerations of your research?
  • How? How much time did your study take? How did you choose participants? How did you collect data and analyze it?

Keep these questions in mind when working out a research design, picking data collection procedures and analysis techniques. If you rely on standard methods, a quick description with a citation would be enough for the methodology part of the research paper structure. But if you employ a unique approach, make sure to describe it in minute detail to ensure anyone can repeat the process and achieve the same results. 

For obvious reasons, the methodology section will differ greatly depending on your field of study and topic. For example, qualitative and quantitative research methods are vastly different. At the same time, quantitative analysis of sociology or linguistics research will be nothing like analyzing blood tests for nursing students or analyzing the success of a marketing campaign for a business and management class. While the tools (i.e., programming language or table processing software) may be similar, the application will be different, and you should highlight these distinctions in your methodology section. 

Although you can put off working on this section of the structure of a research paper, it can be helpful to put your methodology on paper before embarking on the study. A clear idea of the protocols you plan to employ should keep your study on track and minimize methodological errors. 

The research paper results present the study findings as the ultimate product of your research. Instead of the raw data, you can present analysis results and visual aids in the form of tables, figures, and graphs, provide statistical analysis results, and refer interested readers to appendices containing raw data.

Remember to follow the formatting style requirements for tables and figures, which differ for APA and MLA. The same applies to lists and other visual aids. You should also ensure these materials do not destroy your paper’s readability. For example, a three-page table is much more difficult to grasp than a couple of charts highlighting the same data. Moreover, if you plan to present your findings on a poster or a PowerPoint presentation, it pays to work out the best way to present your insights that will fit all formats, including print and projection.

It’s important to draw the line between the results and discussion parts of the research paper structure. The first presents analysis, while the latter relies on interpretations (or implications) of that analysis. Understanding the distinction can be quite challenging, especially if you’re working out the structure of a research paper for the first time.

Discussion and Conclusion

The research paper discussion connects the introduction and research question with the study results. Instead of merely analyzing data, this section should explain whether your initial hypothesis was correct or not. Moreover, the final section, along with the research paper conclusion, should cover the implications of the findings and their potential practical and theoretical applications. This part can also include the limitations of the study and the need for further research if you feel that it could be useful.

It may seem counterproductive, but you shouldn’t shy away from shortcomings, mistakes, and negative results achieved in your study. Instead of waiting for uncomfortable questions from your instructor, present the bad along with the good and hypothesize potential ways of correcting errors or minimizing the negative influences. In some cases, negative results can be just as valuable (if not more so) than positive findings.

Remember to include the research paper references and appendices after the conclusion to wrap up your work and make it better with careful editing, proofreading, and formatting.

What is the purpose of a research paper?

The main objective is to present and share research insights and discoveries, which you should account for when structuring a research paper. Adding literature review and methodology sections is critical for highlighting the study’s relevance and ensuring its reproducibility.

How do I structure the different sections of a research paper?

Structuring a research paper means adding an introduction, literature review, methodology, results, discussion, and conclusion. You can organize each of these sections thematically or chronologically or use a funnel structure, going from the broad context strokes to a narrow view of the problem.

What are the key formatting guidelines for a research paper?

Specific requirements for the structure of a research paper outline and its contents depend on the preferred formatting style. However, at its core, each formatting style focuses on readability. That’s where 12 pt to 14 pt font size and double line spacing come from. Refer to the relevant formatting style handbook for specific recommendations. 

How do I effectively write the introduction and literature review?

The introduction is a critical part of the research paper structure that should include your primary research objective (or question), hypotheses, and the study’s relevance. A literature review is designed to support the claims you make within the introduction by generously using reference data. 

What is the difference between the results and discussion sections?

How to Write an Essay Introduction

The introduction is arguably the most important part of an essay. It sets the tone for the entire piece, grabs the reader's attention, and lays out the main argument. A good introduction not only engages the reader but also guides them into the heart of your essay. UK Writings is an excellent write my essay company . For students who need help with refining their introduction writing skills, reading a UKWritings review can offer valuable insights into the reputation and reliability of this paper writing service. In this post, we'll explore some key tips and strategies to help you write a compelling and effective introduction for your essays.

Understand the Purpose of an Introduction

Before we dive into the specifics, it's essential to understand the primary purpose of an essay introduction. An introduction serves three main functions:

  • Hook the reader: The introduction should pique the reader's interest, making them want to read further.
  • Provide background information: It should provide context and background information necessary for the reader to understand the topic and the essay's main argument.
  • State the thesis: The introduction should clearly present the essay's main argument or thesis statement.

Start With a Compelling Hook

The first few sentences of your introduction are crucial in capturing the reader's attention. You want to start with a compelling hook that piques their interest and makes them want to continue reading. Here are some effective ways to begin your introduction:

  • Startling fact or statistic : Presenting a surprising or thought-provoking fact or statistic related to your topic can immediately grab the reader's attention. Example: "Every year, over 8 million tons of plastic end up in our oceans, posing a serious threat to marine life."
  • Rhetorical question: Asking a thought-provoking question that relates to your topic can engage the reader and make them think about the issue. Example: "Have you ever wondered how our reliance on single-use plastics is impacting the environment?"
  • Quotation : Using a relevant quotation from a respected source can add credibility and intrigue to your introduction. Example: "As Jane Goodall famously said, 'What you do makes a difference, and you have to decide what kind of difference you want to make.'"
  • Anecdote or personal story : A brief, relevant anecdote or personal story can help the reader connect with your topic on a more personal level. Example: "When I was a child, I remember being fascinated by the vibrant colors and intricate patterns of the coral reefs during a family vacation to the Great Barrier Reef."

Set the Context and Provide Background Information

After capturing the reader's attention with a compelling hook, your introduction should provide essential background information and context to help the reader understand the topic and its significance. This background information should be concise and relevant, setting the stage for your main argument without delving too deeply into details.

When providing background information, consider:

  • Historical context: If your topic has a historical aspect, briefly explain the relevant historical events or circumstances.
  • Definitions: Define any key terms or concepts that the reader might not be familiar with.
  • Scope: Clarify the scope of your essay and the specific aspect or angle you'll be exploring.
  • Significance: Explain why your topic is important or relevant and why the reader should care.

Example: "Plastic pollution has become a major environmental concern in recent decades. As our reliance on single-use plastics has increased, so too has the amount of plastic waste ending up in our oceans, landfills, and natural environments. This plastic pollution not only poses a threat to marine life but also has far-reaching consequences for human health and the planet's ecosystems."

State Your Thesis Statement

The thesis statement is the backbone of your essay, and it should be clearly stated in the introduction. Your thesis statement should concisely summarize the main argument or central idea of your essay. It should be specific, focused, and debatable, providing a clear roadmap for the rest of your essay.

When writing your thesis statement, consider:

  • Main argument: What is the main point or argument you'll be making in your essay?
  • Scope: What specific aspect or angle of the topic will you be focusing on?
  • Significance: Why is your argument important or relevant?

Example: "Therefore, it is crucial that we take immediate and decisive action to reduce our reliance on single-use plastics and implement effective strategies to combat plastic pollution in our oceans and natural environments."

Structure and Transitions

While the content of your introduction is essential, the structure and flow are equally important. A well-organized introduction should have a logical progression, guiding the reader smoothly from the hook to the background information and finally to the thesis statement.

To achieve a cohesive structure, use appropriate transitions and signpost words to connect your ideas and guide the reader through your introduction. For example, you could use phrases like "In recent years," "Moreover," "Additionally," or "Therefore" to link your sentences and ideas together.

Example: "In recent years, plastic pollution has become a major environmental concern. Moreover, as our reliance on single-use plastics has increased, so too has the amount of plastic waste ending up in our oceans, landfills, and natural environments. Additionally, this plastic pollution not only poses a threat to marine life but also has far-reaching consequences for human health and the planet's ecosystems. Therefore, it is crucial that we take immediate and decisive action to reduce our reliance on single-use plastics and implement effective strategies to combat plastic pollution in our oceans and natural environments."

Length and Placement

While there is no strict rule on the length of an introduction, a general guideline is to keep it between 10-20% of the total word count of your essay. This ensures that your introduction is substantial enough to provide the necessary background and context without being too long or overwhelming.

It's also important to note that the introduction should be placed at the beginning of your essay, serving as the first section before the body paragraphs and conclusion.

Revise and Refine

Writing a strong introduction is an iterative process, and it's essential to revise and refine your introduction as you write and revise your essay. As you develop your ideas and arguments, you may need to adjust or refine your introduction to better align with the content and direction of your essay.

Don't be afraid to revise your introduction multiple times until you're satisfied that it accurately reflects the focus, tone, and main argument of your essay.

A well-written introduction is the key to capturing your reader's attention and setting the stage for a compelling and persuasive essay. By following these tips and strategies, you can create an introduction that hooks the reader, provides essential context, and clearly states your thesis statement. Remember to start with a compelling hook, provide relevant background information, create a focused thesis statement, maintain a logical structure, and revise and refine your introduction as needed. With a strong introduction in place, you'll be well on your way to writing a successful and impactful essay.

Statistical methods involved in carrying out a study include planning, designing, collecting data, analysing, drawing meaningful interpretation and reporting of the research findings. The statistical analysis gives meaning to the meaningless numbers, thereby breathing life into a lifeless data. The results and inferences are precise only if proper statistical tests are used. This article will try to acquaint the reader with the basic research tools that are utilised while conducting various studies. The article covers a brief outline of the variables, an understanding of quantitative and qualitative variables and the measures of central tendency. An idea of the sample size estimation, power analysis and the statistical errors is given. Finally, there is a summary of parametric and non-parametric tests used for data analysis.

INTRODUCTION

Statistics is a branch of science that deals with the collection, organisation, analysis of data and drawing of inferences from the samples to the whole population.[ 1 ] This requires a proper design of the study, an appropriate selection of the study sample and choice of a suitable statistical test. An adequate knowledge of statistics is necessary for proper designing of an epidemiological study or a clinical trial. Improper statistical methods may result in erroneous conclusions which may lead to unethical practice.[ 2 ]

Variable is a characteristic that varies from one individual member of population to another individual.[ 3 ] Variables such as height and weight are measured by some type of scale, convey quantitative information and are called as quantitative variables. Sex and eye colour give qualitative information and are called as qualitative variables[ 3 ] [ Figure 1 ].

Classification of variables

Quantitative variables

Quantitative or numerical data are subdivided into discrete and continuous measurements. Discrete numerical data are recorded as a whole number such as 0, 1, 2, 3,… (integer), whereas continuous data can assume any value. Observations that can be counted constitute the discrete data and observations that can be measured constitute the continuous data. Examples of discrete data are number of episodes of respiratory arrests or the number of re-intubations in an intensive care unit. Similarly, examples of continuous data are the serial serum glucose levels, partial pressure of oxygen in arterial blood and the oesophageal temperature.

A hierarchical scale of increasing precision can be used for observing and recording the data which is based on categorical, ordinal, interval and ratio scales [ Figure 1 ].

Categorical or nominal variables are unordered. The data are merely classified into categories and cannot be arranged in any particular order. If only two categories exist (as in gender male and female), it is called as a dichotomous (or binary) data. The various causes of re-intubation in an intensive care unit due to upper airway obstruction, impaired clearance of secretions, hypoxemia, hypercapnia, pulmonary oedema and neurological impairment are examples of categorical variables.

Ordinal variables have a clear ordering between the variables. However, the ordered data may not have equal intervals. Examples are the American Society of Anesthesiologists status or Richmond agitation-sedation scale.

Interval variables are similar to an ordinal variable, except that the intervals between the values of the interval variable are equally spaced. A good example of an interval scale is the Fahrenheit degree scale used to measure temperature. With the Fahrenheit scale, the difference between 70° and 75° is equal to the difference between 80° and 85°: The units of measurement are equal throughout the full range of the scale.

Ratio scales are similar to interval scales, in that equal differences between scale values have equal quantitative meaning. However, ratio scales also have a true zero point, which gives them an additional property. For example, the system of centimetres is an example of a ratio scale. There is a true zero point and the value of 0 cm means a complete absence of length. The thyromental distance of 6 cm in an adult may be twice that of a child in whom it may be 3 cm.

STATISTICS: DESCRIPTIVE AND INFERENTIAL STATISTICS

Descriptive statistics[ 4 ] try to describe the relationship between variables in a sample or population. Descriptive statistics provide a summary of data in the form of mean, median and mode. Inferential statistics[ 4 ] use a random sample of data taken from a population to describe and make inferences about the whole population. It is valuable when it is not possible to examine each member of an entire population. The examples if descriptive and inferential statistics are illustrated in Table 1 .

Example of descriptive and inferential statistics

Descriptive statistics

The extent to which the observations cluster around a central location is described by the central tendency and the spread towards the extremes is described by the degree of dispersion.

Measures of central tendency

The measures of central tendency are mean, median and mode.[ 6 ] Mean (or the arithmetic average) is the sum of all the scores divided by the number of scores. Mean may be influenced profoundly by the extreme variables. For example, the average stay of organophosphorus poisoning patients in ICU may be influenced by a single patient who stays in ICU for around 5 months because of septicaemia. The extreme values are called outliers. The formula for the mean is

An external file that holds a picture, illustration, etc.
Object name is IJA-60-662-g003.jpg

where x = each observation and n = number of observations. Median[ 6 ] is defined as the middle of a distribution in a ranked data (with half of the variables in the sample above and half below the median value) while mode is the most frequently occurring variable in a distribution. Range defines the spread, or variability, of a sample.[ 7 ] It is described by the minimum and maximum values of the variables. If we rank the data and after ranking, group the observations into percentiles, we can get better information of the pattern of spread of the variables. In percentiles, we rank the observations into 100 equal parts. We can then describe 25%, 50%, 75% or any other percentile amount. The median is the 50 th percentile. The interquartile range will be the observations in the middle 50% of the observations about the median (25 th -75 th percentile). Variance[ 7 ] is a measure of how spread out is the distribution. It gives an indication of how close an individual observation clusters about the mean value. The variance of a population is defined by the following formula:

An external file that holds a picture, illustration, etc.
Object name is IJA-60-662-g004.jpg

where σ 2 is the population variance, X is the population mean, X i is the i th element from the population and N is the number of elements in the population. The variance of a sample is defined by slightly different formula:

An external file that holds a picture, illustration, etc.
Object name is IJA-60-662-g005.jpg

where s 2 is the sample variance, x is the sample mean, x i is the i th element from the sample and n is the number of elements in the sample. The formula for the variance of a population has the value ‘ n ’ as the denominator. The expression ‘ n −1’ is known as the degrees of freedom and is one less than the number of parameters. Each observation is free to vary, except the last one which must be a defined value. The variance is measured in squared units. To make the interpretation of the data simple and to retain the basic unit of observation, the square root of variance is used. The square root of the variance is the standard deviation (SD).[ 8 ] The SD of a population is defined by the following formula:

An external file that holds a picture, illustration, etc.
Object name is IJA-60-662-g006.jpg

where σ is the population SD, X is the population mean, X i is the i th element from the population and N is the number of elements in the population. The SD of a sample is defined by slightly different formula:

An external file that holds a picture, illustration, etc.
Object name is IJA-60-662-g007.jpg

where s is the sample SD, x is the sample mean, x i is the i th element from the sample and n is the number of elements in the sample. An example for calculation of variation and SD is illustrated in Table 2 .

Normal distribution or Gaussian distribution

Most of the biological variables usually cluster around a central value, with symmetrical positive and negative deviations about this point.[ 1 ] The standard normal distribution curve is a symmetrical bell-shaped. In a normal distribution curve, about 68% of the scores are within 1 SD of the mean. Around 95% of the scores are within 2 SDs of the mean and 99% within 3 SDs of the mean [ Figure 2 ].

Normal distribution curve

Skewed distribution

It is a distribution with an asymmetry of the variables about its mean. In a negatively skewed distribution [ Figure 3 ], the mass of the distribution is concentrated on the right of Figure 1 . In a positively skewed distribution [ Figure 3 ], the mass of the distribution is concentrated on the left of the figure leading to a longer right tail.

Curves showing negatively skewed and positively skewed distribution

Inferential statistics

In inferential statistics, data are analysed from a sample to make inferences in the larger collection of the population. The purpose is to answer or test the hypotheses. A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. Hypothesis tests are thus procedures for making rational decisions about the reality of observed effects.

Probability is the measure of the likelihood that an event will occur. Probability is quantified as a number between 0 and 1 (where 0 indicates impossibility and 1 indicates certainty).

In inferential statistics, the term ‘null hypothesis’ ( H 0 ‘ H-naught ,’ ‘ H-null ’) denotes that there is no relationship (difference) between the population variables in question.[ 9 ]

Alternative hypothesis ( H 1 and H a ) denotes that a statement between the variables is expected to be true.[ 9 ]

The P value (or the calculated probability) is the probability of the event occurring by chance if the null hypothesis is true. The P value is a numerical between 0 and 1 and is interpreted by researchers in deciding whether to reject or retain the null hypothesis [ Table 3 ].

P values with interpretation

If P value is less than the arbitrarily chosen value (known as α or the significance level), the null hypothesis (H0) is rejected [ Table 4 ]. However, if null hypotheses (H0) is incorrectly rejected, this is known as a Type I error.[ 11 ] Further details regarding alpha error, beta error and sample size calculation and factors influencing them are dealt with in another section of this issue by Das S et al .[ 12 ]

PARAMETRIC AND NON-PARAMETRIC TESTS

Numerical data (quantitative variables) that are normally distributed are analysed with parametric tests.[ 13 ]

Two most basic prerequisites for parametric statistical analysis are:

  • The assumption of normality which specifies that the means of the sample group are normally distributed
  • The assumption of equal variance which specifies that the variances of the samples and of their corresponding population are equal.

However, if the distribution of the sample is skewed towards one side or the distribution is unknown due to the small sample size, non-parametric[ 14 ] statistical techniques are used. Non-parametric tests are used to analyse ordinal and categorical data.

Parametric tests

The parametric tests assume that the data are on a quantitative (numerical) scale, with a normal distribution of the underlying population. The samples have the same variance (homogeneity of variances). The samples are randomly drawn from the population, and the observations within a group are independent of each other. The commonly used parametric tests are the Student's t -test, analysis of variance (ANOVA) and repeated measures ANOVA.

Student's t -test

Student's t -test is used to test the null hypothesis that there is no difference between the means of the two groups. It is used in three circumstances:

An external file that holds a picture, illustration, etc.
Object name is IJA-60-662-g013.jpg

where X = sample mean, u = population mean and SE = standard error of mean

An external file that holds a picture, illustration, etc.
Object name is IJA-60-662-g014.jpg

where X 1 − X 2 is the difference between the means of the two groups and SE denotes the standard error of the difference.

  • To test if the population means estimated by two dependent samples differ significantly (the paired t -test). A usual setting for paired t -test is when measurements are made on the same subjects before and after a treatment.

The formula for paired t -test is:

An external file that holds a picture, illustration, etc.
Object name is IJA-60-662-g015.jpg

where d is the mean difference and SE denotes the standard error of this difference.

The group variances can be compared using the F -test. The F -test is the ratio of variances (var l/var 2). If F differs significantly from 1.0, then it is concluded that the group variances differ significantly.

Analysis of variance

The Student's t -test cannot be used for comparison of three or more groups. The purpose of ANOVA is to test if there is any significant difference between the means of two or more groups.

In ANOVA, we study two variances – (a) between-group variability and (b) within-group variability. The within-group variability (error variance) is the variation that cannot be accounted for in the study design. It is based on random differences present in our samples.

However, the between-group (or effect variance) is the result of our treatment. These two estimates of variances are compared using the F-test.

A simplified formula for the F statistic is:

An external file that holds a picture, illustration, etc.
Object name is IJA-60-662-g016.jpg

where MS b is the mean squares between the groups and MS w is the mean squares within groups.

Repeated measures analysis of variance

As with ANOVA, repeated measures ANOVA analyses the equality of means of three or more groups. However, a repeated measure ANOVA is used when all variables of a sample are measured under different conditions or at different points in time.

As the variables are measured from a sample at different points of time, the measurement of the dependent variable is repeated. Using a standard ANOVA in this case is not appropriate because it fails to model the correlation between the repeated measures: The data violate the ANOVA assumption of independence. Hence, in the measurement of repeated dependent variables, repeated measures ANOVA should be used.

Non-parametric tests

When the assumptions of normality are not met, and the sample means are not normally, distributed parametric tests can lead to erroneous results. Non-parametric tests (distribution-free test) are used in such situation as they do not require the normality assumption.[ 15 ] Non-parametric tests may fail to detect a significant difference when compared with a parametric test. That is, they usually have less power.

As is done for the parametric tests, the test statistic is compared with known values for the sampling distribution of that statistic and the null hypothesis is accepted or rejected. The types of non-parametric analysis techniques and the corresponding parametric analysis techniques are delineated in Table 5 .

Analogue of parametric and non-parametric tests

Median test for one sample: The sign test and Wilcoxon's signed rank test

The sign test and Wilcoxon's signed rank test are used for median tests of one sample. These tests examine whether one instance of sample data is greater or smaller than the median reference value.

This test examines the hypothesis about the median θ0 of a population. It tests the null hypothesis H0 = θ0. When the observed value (Xi) is greater than the reference value (θ0), it is marked as+. If the observed value is smaller than the reference value, it is marked as − sign. If the observed value is equal to the reference value (θ0), it is eliminated from the sample.

If the null hypothesis is true, there will be an equal number of + signs and − signs.

The sign test ignores the actual values of the data and only uses + or − signs. Therefore, it is useful when it is difficult to measure the values.

Wilcoxon's signed rank test

There is a major limitation of sign test as we lose the quantitative information of the given data and merely use the + or – signs. Wilcoxon's signed rank test not only examines the observed values in comparison with θ0 but also takes into consideration the relative sizes, adding more statistical power to the test. As in the sign test, if there is an observed value that is equal to the reference value θ0, this observed value is eliminated from the sample.

Wilcoxon's rank sum test ranks all data points in order, calculates the rank sum of each sample and compares the difference in the rank sums.

Mann-Whitney test

It is used to test the null hypothesis that two samples have the same median or, alternatively, whether observations in one sample tend to be larger than observations in the other.

Mann–Whitney test compares all data (xi) belonging to the X group and all data (yi) belonging to the Y group and calculates the probability of xi being greater than yi: P (xi > yi). The null hypothesis states that P (xi > yi) = P (xi < yi) =1/2 while the alternative hypothesis states that P (xi > yi) ≠1/2.

Kolmogorov-Smirnov test

The two-sample Kolmogorov-Smirnov (KS) test was designed as a generic method to test whether two random samples are drawn from the same distribution. The null hypothesis of the KS test is that both distributions are identical. The statistic of the KS test is a distance between the two empirical distributions, computed as the maximum absolute difference between their cumulative curves.

Kruskal-Wallis test

The Kruskal–Wallis test is a non-parametric test to analyse the variance.[ 14 ] It analyses if there is any difference in the median values of three or more independent samples. The data values are ranked in an increasing order, and the rank sums calculated followed by calculation of the test statistic.

Jonckheere test

In contrast to Kruskal–Wallis test, in Jonckheere test, there is an a priori ordering that gives it a more statistical power than the Kruskal–Wallis test.[ 14 ]

Friedman test

The Friedman test is a non-parametric test for testing the difference between several related samples. The Friedman test is an alternative for repeated measures ANOVAs which is used when the same parameter has been measured under different conditions on the same subjects.[ 13 ]

Tests to analyse the categorical data

Chi-square test, Fischer's exact test and McNemar's test are used to analyse the categorical or nominal variables. The Chi-square test compares the frequencies and tests whether the observed data differ significantly from that of the expected data if there were no differences between groups (i.e., the null hypothesis). It is calculated by the sum of the squared difference between observed ( O ) and the expected ( E ) data (or the deviation, d ) divided by the expected data by the following formula:

An external file that holds a picture, illustration, etc.
Object name is IJA-60-662-g018.jpg

A Yates correction factor is used when the sample size is small. Fischer's exact test is used to determine if there are non-random associations between two categorical variables. It does not assume random sampling, and instead of referring a calculated statistic to a sampling distribution, it calculates an exact probability. McNemar's test is used for paired nominal data. It is applied to 2 × 2 table with paired-dependent samples. It is used to determine whether the row and column frequencies are equal (that is, whether there is ‘marginal homogeneity’). The null hypothesis is that the paired proportions are equal. The Mantel-Haenszel Chi-square test is a multivariate test as it analyses multiple grouping variables. It stratifies according to the nominated confounding variables and identifies any that affects the primary outcome variable. If the outcome variable is dichotomous, then logistic regression is used.

SOFTWARES AVAILABLE FOR STATISTICS, SAMPLE SIZE CALCULATION AND POWER ANALYSIS

Numerous statistical software systems are available currently. The commonly used software systems are Statistical Package for the Social Sciences (SPSS – manufactured by IBM corporation), Statistical Analysis System ((SAS – developed by SAS Institute North Carolina, United States of America), R (designed by Ross Ihaka and Robert Gentleman from R core team), Minitab (developed by Minitab Inc), Stata (developed by StataCorp) and the MS Excel (developed by Microsoft).

There are a number of web resources which are related to statistical power analyses. A few are:

  • StatPages.net – provides links to a number of online power calculators
  • G-Power – provides a downloadable power analysis program that runs under DOS
  • Power analysis for ANOVA designs an interactive site that calculates power or sample size needed to attain a given power for one effect in a factorial ANOVA design
  • SPSS makes a program called SamplePower. It gives an output of a complete report on the computer screen which can be cut and paste into another document.

It is important that a researcher knows the concepts of the basic statistical methods used for conduct of a research study. This will help to conduct an appropriately well-designed study leading to valid and reliable results. Inappropriate use of statistical techniques may lead to faulty conclusions, inducing errors and undermining the significance of the article. Bad statistics may lead to bad research, and bad research may lead to unethical practice. Hence, an adequate knowledge of statistics and the appropriate use of statistical tests are important. An appropriate knowledge about the basic statistical methods will go a long way in improving the research designs and producing quality medical research which can be utilised for formulating the evidence-based guidelines.

How to Write an Explanatory Essay

How to Write an Explanatory Essay

  • Smodin Editorial Team
  • Published: May 24, 2024

A study from the English Language Teaching Educational Journal found that students encounter difficulty in organizing thoughts, generating ideas, and understanding writing processes when writing essays [1]. These are all key components of putting together a good explanatory essay. If this sounds like you, then don’t worry.

With the right approach, you can seamlessly combine all these components. This guide will give you a simple step-by-step strategy for writing an explanatory essay. It’ll also give you handy writing tips and tool suggestions, like utilizing artificial intelligence.

With this guide, you’ll be able to write an explanatory essay with confidence.

1. Develop a strong thesis statement

Crafting a strong thesis statement is the cornerstone of any well-written explanatory essay. It sets the stage for what your essay will cover and clarifies the main point you’re going to explain. Here’s how to create a thesis:

  • Find the main idea : Start by pinpointing the key concept or question you want to explain. Develop a clear purpose for the essay. This will guide your research and writing process for your explanatory paper. Use other reputable explanatory essay examples to guide your ideas. This may involve exploring other explanatory essay topics within the same field.
  • Be specific : A vague thesis can confuse readers. So, make sure your statement is clear. If you’re explaining a complex process, break it down to its key points. After that, break it into a clear, concise statement that’s easy to understand.
  • Reflect objectivity : Explanatory essays educate and inform. They do not argue a point. So, your thesis should take an unbiased stance on the topic. It should present the facts as they are, not as you interpret them.
  • Use tools like the Smodin Writer : Smodin Writer does all the heavy lifting by leveraging the power of artificial intelligence. With it, you can generate an essay with a thesis statement. How, you ask? Through its dedicated thesis generator . It can create a statement that’s both strong and relevant. Plus, it can pull in all the most interesting information based on your topic to further enrich your thesis statement.

Make your thesis clear, informative, and neutral. This sets a strong foundation for an effective explanatory essay. Next, let’s look at how to gather the information you’ll need to support this thesis effectively.

2. Research and gather information

You need to conduct thorough research that will back your thesis with credible sources and relevant evidence. This will make your explanatory essay both informative and persuasive. Here’s a step-by-step guide to conducting effective research:

  • Start with a plan: Put together an explanatory essay outline that includes the information you need to support your thesis. The plan should list the best sources, like academic journals, books, reputable websites, or scholarly articles.
  • Use credible sources: They ensure the accuracy of your essay. Libraries, academic databases, and certified websites are excellent places to find trustworthy information.
  • Seek detailed information: Look for the most current sources that explain your topic well and provide unique insights related to or opposing your thesis statement. This depth is crucial for explaining complex ideas clearly and thoroughly in your explanatory papers. Pay attention to the explanatory essay structure to guide your topic of choice (more on this later).
  • Gather relevant evidence: Collect data, stats, and examples. They should directly support your main points. Make sure this evidence is directly related to your topic and enhances your narrative.
  • Employ digital tools: Tools like Smodin’s Research Assistant can accelerate your research process. Smodin’s tools can help you find detailed information quickly, ensuring that the data you use is up-to-date and relevant.
  • Document your sources: As you conduct research, keep a meticulous record of where your information comes from. This practice will help you make an accurate bibliography. It can save you time when you need to refer back to details or verify facts. Again, this is something that’s covered thanks to Smodin’s Citation Machine.
  • Evaluate your findings: Critically assess the information you collect. Ensure it provides a balanced view and covers the necessary aspects of your topic to give a comprehensive overview of your essay.

By following these steps, you can gather a rich pool of information that provides a strong backbone for your explanatory essay. Now, you can start structuring your findings into well-organized body paragraphs.

3. Structure body paragraphs

Once you’ve gathered relevant evidence through thorough research, it’s time to organize it. You should put it into well-structured body paragraphs that follow a logical flow. Here’s how to structure each body paragraph for a strong explanatory essay:

  • Decide how many paragraphs to use : It will depend on your topic’s complexity and the needed detail. Typically, three to five paragraphs are suitable, but longer essays may require more. An explanatory essay example on your topic of choice will be helpful.
  • Start with a topic sentence : Each body paragraph should begin with a clear topic sentence that introduces the main idea of the paragraph. This sentence will act as a roadmap for the paragraph, giving the reader a sense of what to expect.
  • Provide supporting evidence : After the topic sentence, share the evidence from your research. Ensure the evidence is relevant and directly supports the paragraph’s topic sentence.
  • Give a detailed explanation : Follow the evidence with an analysis or explanation that ties it back to the thesis statement. This step is crucial for maintaining logical flow throughout your body paragraphs.
  • Use linking words : They connect body paragraphs smoothly, ensuring the reader can follow your argument.
  • End each body paragraph with a closing sentence : It should sum up the point and move to the next idea.

Following this structure will help your body paragraphs support your thesis. These paragraphs will also offer a clear, detailed explanation of your essay topic. Strong body paragraphs are essential to maintain objectivity in your writing.

4. Maintain objectivity

An explanatory essay aims to inform and educate, which makes maintaining objectivity crucial. Staying neutral lets readers form their own opinions based on facts. This ensures the writing is both reliable and informative. Here’s how to maintain objectivity:

  • Avoid personal opinions: Your goal is to provide a comprehensive understanding of the topic. Refrain from injecting your personal opinion or biases. Instead, stick to presenting factual information that supports the thesis.
  • Use relevant evidence: As mentioned, ground your arguments with relevant evidence from credible sources. Back up your main points with data and use research findings and verified details. This will make the explanatory article trustworthy.
  • Provide a balanced view: In cases with multiple perspectives, offer a balanced view. Cover each side fairly. Even if one view prevails in consensus, acknowledging others gives readers a broader understanding.
  • Adopt neutral language: Be careful with word choice and tone. Neutral language implies words that don’t encourage or illustrate bias. This helps avoid emotionally charged phrases and keeps the writing objective.
  • Cite sources accurately: Proper citation of sources provides accountability for the evidence presented. This transparency builds credibility and shows you’ve conducted research thoroughly. It’s also worth noting that different intuitions have different citation styles like APA and Chicago, which is important to note before starting your essay.
  • Review for biases: After drafting your essay, review it with an eye for biases. Ensure no part leans too much on one viewpoint. And, don’t dismiss an opposing perspective without cause.

Maintaining objectivity enhances the clarity and reliability of explanatory writing. Let’s now focus on crafting an introduction and conclusion that bookend your work effectively.

5. Craft an effective introduction and conclusion

A good introduction and a strong conclusion frame your explanatory essay. They give context at the start and reinforce the main points at the end. Here’s how to craft an effective introduction and conclusion.

In the introduction:

  • Hook your reader in the introduction : Use an interesting fact, a compelling quote, or a surprising statistic.
  • Provide background information : Be brief and offer only the essential context the reader needs to fully understand the topic. This should give the audience a foundational understanding before diving deeper into your main points.
  • Include the thesis statement : Clearly state your thesis near the end of the introduction. This statement will outline the essay’s direction and give readers a preview of the body paragraphs.

In the conclusion:

  • Summarize the key points : Start your explanatory essay conclusion with a summary. It should cover the main points from the body paragraphs. This summary should help readers recall and reinforce the information they’ve just read.
  • Restate the thesis : Repeat your thesis again but in a new way. Explain how the evidence from the body paragraphs supported or clarified it.
  • Provide a conclusion : End the essay with a statement that wraps up the argument. This statement should resonate with the reader. It should leave them with an impression that stresses the topic’s importance.

An effective introduction and conclusion give the essay structure and coherence. They guide readers from start to finish. The next step is revising and editing your entire essay for clarity and precision.

6. Revise and check clarity

Revising and editing are key in writing. They make sure your essay is clear, joined, and polished. Here’s how to refine your writing using an explanatory essay checklist and proven academic writing techniques:

  • Take a break: Before diving into revisions, step away from your essay for a few hours or even a day. This break will help you return with fresh eyes, making it easier to spot errors or inconsistencies.
  • Follow an essay checklist: Create or use a checklist to ensure your essay has all the needed parts. It needs a strong intro with a clear thesis, well-structured body paragraphs, good sources, and a short conclusion. Check that your arguments follow a logical flow and that all relevant evidence is directly linked to your thesis statement.
  • Check for clarity and conciseness: Academic writing needs clarity. So, make sure each paragraph and sentence conveys your point. Don’t use unnecessary jargon or overly complex language. Keep sentences concise while maintaining detailed explanations of your main points.
  • Verify facts and citations: Make sure all facts, data, and quotes in the essay are accurate. Also, check that they are cited in the required academic style (e.g. MLA, APA). Improper citations can undermine the credibility of your writing.
  • Review the grammar and style: Look for common grammar mistakes, punctuation errors, and awkward phrasing. Reading the essay aloud can help catch odd sentence structures or confusing wording.
  • Seek feedback: Share your essay with a peer or use online tools to get constructive criticism. A second perspective can highlight issues you might have missed.

These editing steps will help you produce a polished essay that clearly explains your main points and holds up to academic scrutiny.

Explanatory Essay Format

Understanding the explanatory essay format is key to a well-structured and logical paper. Here’s a basic breakdown of the format for an explanatory essay:

Introduction paragraph

  • Begin with an interesting sentence to capture the reader’s attention.
  • Give a short intro. It should set the topic and outline the essay’s purpose.
  • Present a clear thesis statement summarizing the main idea of the entire essay.

Body paragraphs

  • Organize the body paragraphs around logical subtopics related to the essay topic.
  • Start each body paragraph with a topic sentence that aligns with the thesis.
  • Show evidence from good sources. Also, give key details for each main point.
  • Incorporate a robust concluding statement per paragraph that drives home your point and links to the ideas in the next paragraph/section.
  • Summarize the key points.
  • Provide a final statement that reinforces the main idea without introducing new information.
  • Craft a concluding statement that leaves your teacher or professor with a lasting impression.

Following this essay outline ensures that your paper has a clear flow. This makes it easy for readers to understand and follow your argument.

Powerful Academic Phrases to Improve Your Essay Writing 

academic phrases

Adopting a formal style of writing is crucial for any type of academic writing, be it scholarly articles, research papers or essays. It requires a deep understanding of the subject matter, the ability to analyze and synthesize complex information, and the skill to communicate ideas effectively. One of the primary challenges of academic writing is the need to balance clarity with accuracy.  

There are various factors that should be borne in mind in academic writing. The writing should be clear and precise. It should be well structured with a clear focus while demonstrating the rigor with which the research was conducted. Long winding sentences and emotional language must be completely avoided. While discipline specific language should be used, jargon must be avoided. In other words, academic writing is not easy. However, by using the right words and academic phrases, you can deliver clear, concise writing that can elevate your scholarly papers or essays.  

In this article we will look at a few strong academic phrases that can go a long way in improving your academic essay writing.

Table of Contents

Comparing and contrasting, providing examples, elaborating on information, indicating uncertainty, summarising, academic phrases for various situations.

In writing an academic essay, arguments and ideas need to be built and articulated in a compelling manner. These should be supported with appropriate evidence. Furthermore, verifiable facts and examples must be presented in an engaging way and the entire essay should be well structured.  

In all these, the usage of right academic phrases becomes helpful. Depending on what you want to convey, different academic phrases can be used in various situations as discussed below. 

Very often in essays you may have to engage in the process of comparing and contrasting information, key aspects of two phenomena taken for study, or various sources for your literature review and so on. You will have to bring in to your discussion not just the similarities to your arguments, but also opposing or conflicting perspectives.  

Use of appropriate phrases will help organically bring in such similar or contrasting information. For example, some of the phrases that can be used to discuss similarities and differences include: In comparison or by contrast, however, conversely, alternatively, whereas, on the other hand, likewise, in the same way and so on. Example: “The author expresses his opinion based on anecdotal references. By contrast the survey he quotes and tries to argue against is more plausible with the rigorous data it has collected.”  

While writing an academic essay, you are required to support and expand your ideas and arguments through the use of examples. Phrases that can be used to provide examples include: for example, for instance, to illustrate, to exemplify, to demonstrate. 

Example: “Climate and weather patterns are changing rapidly and its ramifications are staring us in the face. For example, look at what is happening with the incessant rains pouring down during certain summer months.”  

As you structure your narrative, you will have to elaborate at various points on the information, ideas, and arguments that you are presenting. This has to be done in a manner that does not adversely affect the smooth flow of the narrative. It is here that the usage of appropriate phrases is crucial to uplift the quality of your essay. Using phrases such as moreover, furthermore, in other words, in addition and so on can aid in providing additional information. 

Example: “Rising temperatures are greatly impacting the health of children belonging to vulnerable groups in parts of the Asian sub-continent. Moreover, the lack of adequate government support and dismal welfare measures is making lives harder for such families.” 

While writing research papers or essays, researchers often acknowledge the limitations of their studies and the possibilities for conflicting or opposing views. Such recognition is pertinent for the advancement of scientific knowledge. There are various phrases that can be used to indicate uncertainty such as: it could be argued that the data suggest that evidence suggest that, or it is possible due to. 

Example: “The evidence suggests that the new teaching methods are beneficial and can be considered as an alternative to existing methods”. 

The concluding part of your essay should be a summary of your main ideas and arguments and its significance. To this end, the following phrases can be utilized: to summarise, to conclude, above all, or most significantly.  

Example: “To conclude, evidence points to the positive impact of periodic creative workshops on children’s cognitive development.”   

While academic writing may be challenging, mastering the use of appropriate academic phrases, avoiding jargon, and delivering clear, concise writing can elevate one’s writing to a higher and contribute to the advancement of knowledge in their respective fields.
