What types of information should you include in your introduction?
In the introduction of your thesis, you’ll be trying to do three main things, which are called Moves:
- Move 1 establish your territory (say what the topic is about)
- Move 2 establish a niche (show why there needs to be further research on your topic)
- Move 3 introduce the current research (make hypotheses; state the research questions)
Each Move has a number of stages. Depending on what you need to say in your introduction, you might use one or more stages. Table 1 provides you with a list of the most commonly occurring stages of introductions in Honours theses (colour-coded to show the Moves). You will also find examples of Introductions, divided into stages with sample sentence extracts. Once you’ve looked at Examples 1 and 2, try the exercise that follows.
Most thesis introductions include SOME (but not all) of the stages listed below. There are variations between different Schools and between different theses, depending on the purpose of the thesis.
Stages in a thesis introduction
- state the general topic and give some background
- provide a review of the literature related to the topic
- define the terms and scope of the topic
- outline the current situation
- evaluate the current situation (advantages/ disadvantages) and identify the gap
- identify the importance of the proposed research
- state the research problem/ questions
- state the research aims and/or research objectives
- state the hypotheses
- outline the order of information in the thesis
- outline the methodology
Now read the following two examples from past theses, noting which stages are included in each example. How does example 1 differ from example 2?
Read the following sample sentence extracts from Honours theses Introductions. When you have decided what stage of the Introduction they belong to, refer to the stages in a thesis introduction and give each sentence extract a number. Then check the suggested answer to see if your answer agrees with ours.
Example 3: The IMO Severe-Weather Criterion Applied to High-Speed Monohulls (School of Mechanical and Manufacturing Engineering)
Example 4: The Steiner Tree Problem (School of Computer Science and Engineering)
What does this tell you about thesis introductions?
Well, firstly, there are many choices that you can make. You will notice that there are variations not only between the different Schools in your faculty, but also between individual theses, depending on the type of information that is being communicated. However, there are a few elements that a good Introduction should include, at the very minimum:
- Either Statement of general topic Or Background information about the topic;
- Either Identification of disadvantages of current situation Or Identification of the gap in current research;
- Identification of importance of proposed research
- Either Statement of aims Or Statement of objectives
- An Outline of the order of information in the thesis
Note: this introduction includes the literature review.

|Stage 1||Sample sentence extracts (the complete Introduction is 17 pages long)|
|Give some background (p.1 of 17)|
1.1 Fluoride in the environment
Molecular fluorine (F2) is the most electronegative of the elements and therefore is highly reactive. Due to its high reactivity it is never found in its elemental form in nature. It combines directly at both ordinary or elevated temperatures with all other elements except oxygen, nitrogen, and the lighter noble gases (Cotton & Wilkinson, 1980).
Example 5.2 (extract 2): The effects of Fluoride on the reproduction of three native Australian plant Species (School of Geography)
|Stage 2||Sample sentence extracts|
|Provide a review of the literature related to the topic (p.2 of 17)||The main source of elevated fluoride in plants comes from atmospheric industrial pollution. Because of its extensive industrial use, hydrogen fluoride is probably the greatest single atmospheric fluoride contaminant and is generally considered to be the most important plant pathogenic fluoride (WHO, 1984; Treshow, 1965)… However, fluorides can cause damage to sensitive plant species even at extremely low fluoride concentrations(Hill,1969), accumulate in large amounts within the plant and cause disease if ingested by herbivores(Weinstein, 1977).|
|Stages 4 and 5||Sample sentence extracts|
|Outline the current situation; Evaluate the current situation and indicate a gap (p.12 of 17)||Doley (1981) summarized several unpublished studies that compared the sensitivity rankings of 24 species according to the responses of photosynthesis and the development of visible injury symptoms. This analysis showed that for nine species, photosynthesis measurements indicated greater sensitivity than was obvious from visible assessment, and for seven species the converse applied. This indicated that, while it may generally be true that physiological responses occur at lower doses than visible injury, this does not always appear to be the case.|
Example 5.4 (extract 4): The effects of Fluoride on the reproduction of three native Australian plant Species (School of Geography)
|Stage 7||Sample sentence extracts|
|State the research problem(p.4 of 17)||In many Australian plant species, young expanding leaves appear much more severely injured by gaseous fluorides than are old leaves. This suggests, either that the young leaf tissues are more sensitive to fluoride than mature tissues, or that sufficient fluoride enters the tissues directly through the cuticle to disrupt normal leaf development before the stomata have fully developed and opened(Doley, 1986a). This question has not been resolved due to the inability to accurately localize low concentrations of fluoride(Doley, 1986a)|
Example 5.5 (extract 5): The effects of Fluoride on the reproduction of three native Australian plant Species (School of Geography)
|Stage 8||Sample sentence extracts|
|State the research aims and /or research objectives (extract p.16 of 17)||Knowledge of the effects of fluoride on the reproductive processes of species within a forest community will help predict potential changes within the community following an increase in atmospheric fluoride due to additional industrial sources, such as aluminium smelters. For these reasons, this project was designed to investigate the reproductive processes of selected species in a woodland near the aluminium smelter at Tomago.|
Example 5.6 (extract 6): The effects of Fluoride on the reproduction of three native Australian plant Species (School of Geography)
|Stage 11||Sample sentence extracts|
|State the outline of the Methodology (extract p.17 of 17).||Germination trials were performed on seeds collected from each species along the fluoride gradient to determine if fluoride has an effect on their viability and hence the regeneration fitness of each species. A density study was used to determine if there were any differences between numbers of mature and immature trees, number of trees producing seed follicles and the number of trees flowering in this season along a fluoride gradient. By using soils collected at various distances away from the smelter the study also investigated differences in germination from the natural soil seed reserve along a fluoride gradient.|
Since the dawn of man, writing has been used to communicate ideas. In academic settings, ideas are typically communicated using formal types of writing such as essays. Most academic essays contain an introductory paragraph, which includes a thesis.
The Oxford English Dictionary defines an introduction as, “A preliminary explanation prefixed to or included in a book or other writing; the part of a book which leads up to the subject treated, or explains the author’s design or purpose. Also, the corresponding part of a speech, lecture, etc.”
Michigan State University student Sally used to have a lot of difficulty writing introductions. Once she had suffered through writing dozens of painful introductions, she decided to look up some tips on how to introduce your essay, and after that she got a lot better.
Introductions can be tricky. Because the introduction is the first portion of your essay that the reader encounters, the stakes are fairly high for your introduction to be successful. A good introduction presents a broad overview of your topic and your thesis, and should convince the reader that it is worth their time to actually read the rest of your essay. Below are some tips that will make writing an introduction a little less daunting, and help us all to write essays that don’t make our professors want to bang their heads against the wall.
- Start your introduction broad, but not too broad. When I first started writing formal essays, I didn’t really know how broad to go with my intros. A brief paragraph on Hamlet would suddenly include irrelevant details about Shakespeare’s childhood, then grow out to be a history of Western literature, and then a history of the universe itself. Do not write an introduction like this; this kind of intro is confusing and makes the reader wonder where exactly you’re going with your essay.Your introduction should provide the reader with a sense of what they should expect out of your essay, not to expound upon every piece of knowledge ever developed by man. Go ahead and start relatively broad, then narrow to your thesis, but make sure you’re still on topic.
- Provide relevant background, but don’t begin your true argument. It’s fine to give a bit of context to your essay in the introduction, but the real meat of your argument should be located in your body paragraphs. A good test to see if information should go in a body or introductory paragraph is to ask yourself a few questions. Is this providing context or evidence? Does this introduce my argument, or try to prove it? True evidence or proof deserves a body paragraph. Context and background most likely belong in your introduction.
- Provide a thesis. The majority of the time, your thesis, or main argument, should occur somewhere towards the end of your introduction. It is a typical convention to put your thesis as the last sentence of your first paragraph. My personal opinion is that it can sometimes be awkward to shove your thesis in one specific place if it doesn’t necessarily fit, but if your thesis works in that position, that is the best place for it. That being said, if you absolutely can’t include your thesis in that location, go ahead and stick it somewhere else.
- Provide only helpful, relevant information. Anecdotes can be an interesting opener to your essay, but only if the anecdote in question is truly relevant to your topic. Are you writing an essay about Maya Angelou? An anecdote about her childhood might be relevant, and even charming. Are you writing an essay about safety regulations in roller coasters? Go ahead and add an anecdote about a person who was injured while riding a roller coaster. Are you writing an essay about Moby Dick? Perhaps an anecdote about that time your friend read Moby Dick and hated it is not the best way to go. The same is true for statistics, quotes, and other types of information about your topic.
- Try to avoid clichés. Some types of introductions may have once been successful, but have been used so often that they have become tired and clichéd. Starting your essay with a definition is a good example of one of these conventions. At this point, starting with a definition is a bit boring, and will cause your reader to tune out.
- Don’t feel pressured to write your intro first. Sometimes it can be difficult to figure out exactly what information is relevant to your introduction until you’ve written the piece itself. Personally, I find that my writer’s block is always strongest when writing the introduction. If you are having trouble with your intro, feel free to write some, or all, of your body paragraphs, and then come back to it. You might find it a bit easier to write your introduction once you’re more comfortable with the essay as a whole.
- Convince the reader that your essay is worth reading. Your reader should finish the introduction thinking that the essay is interesting or has some sort of relevance to their lives. A good introduction is engaging; it gets the audience thinking about the topic at hand and wondering how you will be proving your argument. Good ways to convince your reader that your essay is worthwhile is to provide information that the reader might question or disagree with. Once they are thinking about the topic, and wondering why you hold your position, they are more likely to be engaged in the rest of the essay.
Basically, a good introduction provides the reader with a brief overview of your topic and an explanation of your thesis. A good introduction is fresh, engaging, and interesting. Successful introductions don’t rely on clichés or irrelevant information to demonstrate their point. Be brief, be concise, be engaging. Good luck.
