Introductions In English Essays On Science

SUMMARY:

  • A good introductory paragraph 1. gets your reader’s attention, 2. introduces your topic, and 3. presents your stance on the topic (thesis).

Right after your title is the introductory paragraph. Like an appetizer for a meal, the introductory paragraph sets up the reader’s palate and gives him a foretaste of what is to come. You want start your paper on a positive note by putting forth the best writing possible.

Like writing the title, you can wait to write your introductory paragraph until you are done with the body of the paper. Some people prefer to do it this way since they want to know exactly where their paper goes before they make an introduction to it. When you write your introductory paragraph is a matter of personal preference.

Your introductory paragraph needs to accomplish three main things: it must 1. grip your reader, 2. introduce your topic, and 3. present your stance on the topic (in the form of your thesis statement). If you’re writing a large academic paper, you’ll also want to contextualize your paper’s claim by discussing points other writers have made on the topic.

There are a variety of ways this can be achieved. Some writers find it useful to put a quote at the beginning of the introductory paragraph. This is often an effective way of getting the attention of your reader:

“Thomas Jefferson’s statement in the Declaration of Independence that “all men are created equal” seems contrary to the way he actually lived his life, bringing into question the difference between the man’s public and private lives…”

Hmm. Interesting…Tell me more. This introduction has set off the paper with an interesting quote and makes the reader want to continue reading. How has Jefferson’s public life differed from his private life? Notice how this introduction also helps frame the paper. Now the reader expects to learn about the duality of Thomas Jefferson’s life.

Another common method of opening a paper is to provide a startling statistic or fact. This approach is most useful in essays that relate to current issues, rather than English or scientific essays.

“The fact that one in every five teenagers between the ages of thirteen and fifteen smokes calls into question the efficacy of laws prohibiting advertising cigarettes to children…”

The reader is given an interesting statistic to chew on (the fact that so many children smoke) while you set up your paper. Now your reader is expecting to read an essay on cigarette advertising laws.

When writing English papers, introducing your topic includes introducing your author and the aspect of the text that you’ll be analyzing.

“Love is a widely felt emotion. In The Count of Monte Cristo, Alexandre Dumas uses the universality of love to develop a connection with his reader…”

Here, the reader is introduced to the piece of text that will be analyzed, the author, and the essay topic. Nice.

The previous sample introduction contains a general sentence at the beginning that bring up a very broad topic: love. From there, the introductory paragraph whittles down to something more specific:
how Dumas uses love in his novel to develop a connection with the reader. You’d expect this paragraph to march right on down to the thesis statement,
which belongs at the end of the introductory paragraph. Good introductory paragraphs often have this ‘funnel’ sort of format–going from something broad (such as love) to something more specific until the thesis is presented.

Try to avoid the some of the more hackneyed openers:

  • “Have you ever wondered why…”
  • “Webster’s dictionary defines…”
  • “X is a very important issue facing America today…”

 

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.
