Purpose Of Introductions In Research Papers

I. Structure and Approach

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

  1. What is this?
  2. Why should I read it?
  3. 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] 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:  Even though the introduction is the first main section of a research paper, it is often useful to finish the introduction late in the writing process because the structure of the paper, the reporting and analysis of results, and the conclusion will have been completed. 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 limitiations 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

The overarching goal of your introduction is to make your readers want to read your paper. The introduction should grab the reader's attention. Strategies for doing this can be to:

  1. Open with a compelling story,
  2. Include a strong quotation or a vivid, perhaps unexpected anecdote,
  3. Pose a provocative or thought-provoking question,
  4. Describe a puzzling scenario or incongruity, or
  5. Cite a stirring example or case study that illustrates why the research problem is important.

NOTE:  Choose only one strategy for engaging your readers; avoid giving an impression that your paper is more flash than substance.

Writing an Introduction

Tip Sheet 17


Ask these questions:

What is it?

An introduction is the first paragraph of a written research paper, or the first thing you say in an oral presentation, or the first thing people see, hear, or experience about your project.

It has two parts:

1. A general introduction to the topic you will be discussing

2. Your Thesis Statement


Why do it?

Without an introduction it is sometimes very difficult for your audience to figure out what you are trying to say. There needs to be a thread of an idea that they will follow through your paper or presentation. The introduction gives the reader the beginning of the piece of thread so they can follow it.


When do I do it?

Many books recommend writing your introduction last, after you finish your project. This is to make sure that you introduce what you are actually going to say.
If your project changes in the creating process, it is important to make sure that your introduction accurately reflects what you will be saying. If, however, you have written a good outline and stick to it, then it is fine to start writing your introduction first. Just make sure in your proofreading that you have kept the thread consistent throughout the paper.


How do I do it?

Start with a couple of sentences that introduce your topic to your reader. You do not have to give too much detailed information; save that for the body of your paper. Make these sentences as interesting as you can. Through them, you can hook a reader and get them very interested in the line of thinking you are going to develop in your project.

Then state your thesis, which may be done in one or more sentences. The length of your introduction depends on the length and complexity of your project, but generally it should not exceed one page unless it is a very long project or a book. The average length of an introduction is one half a page.


Some Examples:

For the example, the regular text is the general introduction to the topic. The BOLD text is the writer's Thesis Statement.

Example 1

Teenagers in many American cities have been involved in more gangs in the last five years than ever before. These gangs of teens have been committing a lot of violent crimes. The victims of these crimes are both gang members and people outside of gangs. Many people do not want to travel to areas in our cities because of the danger from this problem.  For this terrible situation to stop, it is going to take a combined effort on the part of many people. Excellent, supervised after-school programs, more jobs available for teens, and healthy family relationships will go a long way towards ending this crisis in our society.

Example 2

During the Middle Ages in Europe and the Middle East there was much armed conflict between Christians and Muslims. Christians called these conflicts the Crusades because they were fighting under the sign of the cross to save the holy lands of the Bible from being desecrated by non-Christians. However, the true reason for fighting for these lands was less than holy. It was mainly a desire for economic gain that prompted the Christian leaders to send soldiers to fight in the Holy Land.


An introduction gives the reader an idea of where you are going in your project so they can follow along. You can give them more background details and supporting evidence for your thesis in the body of the paper itself.
