The document provides guidance on how to write effective introductions for essays. It explains that introductions should indicate the topic, describe the overall structure of the essay, and state the thesis. Two sample introductions are analyzed, with the second introduction positioned as more effective because it frames the topic knowledgeably and states the thesis confidently without using words like "essay" or "thesis". Frequently asked questions about introductions are also addressed.

Notes de l'éditeur
This version of the presentation includes notes for the instructor. The presentation has been designed so that each slide is self-explanatory and its function clear. Review the presentation first, as you would your own lecture material. Then, when it comes time to give the presentation, simply read out the slides to your audience, adding your own observations, anecdotes and humour as you go. For extra guidance, instructional notes have been provided for each slide. The presentation has been designed for general use, with no particular course in mind. You may feel that some slides are not relevant to your particular case. Simply omit or modify those slides to suit your requirements, or insert slides of your own in the slide-show.
Emphasize the importance of a good introduction. Relate the introduction of an essay to first impressions at an interview! First impressions are important.
Explain how an introduction functions – discuss the roles that an introduction plays. You can take suggestions from the audience and discuss them.
Prepare the audience for an example of a good but predictable introduction: set the scenario of a student who has completed the body of the essay and now has to write an introduction. If the audience asks why the student did not write the introduction first, say that there is a good reasons for this but you will come to that later.
Give an example of a good but predictable introduction – one that uses words like ‘essay’ and ‘thesis’. Make sure that everyone is aware of the three components: topic, organization, and thesis.
Explain that there is nothing wrong with this introduction, but that there are ways in which it could be improved. Take suggestions from the audience about how to improve it. Prepare the audience for the next three slides, where you will discuss each of the three components (topic, organization, thesis) of this introduction.
Explain that there is nothing wrong with the structure-sentences. Make sure everyone is aware of organizational words such as ‘first’, ‘second’, ‘next’, ‘finally’, and so on. Explain that with practice, it is possible to write a better introduction that conveys the organization of an essay without using many overt organizational words or phrases.
Explain that a topic-sentence is best when it does not actually include words or phrases that overtly refer to the essay, such as “this essay is about…” Ask your audience how they usually introduce the topic. It is likely that up to now they have used such phrases!
Stress the importance of striking an assertive tone in the introduction, especially when it comes to the thesis. Explain that the reader needs to feel confident that the author of the essay is in command of their material and knows where they are going with it. At this point, be prepared to take questions or suggestions from the audience – maybe even allow students to express the difficulties that they have in writing their introductions.
Prepare your audience for another example of an introduction – one that takes into account all the points that you have just made about the flaws in the previous example.
Give an example of an improved introduction – one that does not use words like “essay”, “topic”, or “thesis”. Make sure that your audience is aware of the three components (topic-sentences, organizational sentences, and thesis-sentences) in this example. Allow them time to read it, and read it out loud to them if necessary, but do not discuss it until the next slide.
In this, and in the following slide, discuss and emphasize the point that the introduction has successfully conveyed the topic, organization of the body of the essay, and the thesis, without using words like ‘essay’, ‘topic’, ‘first’, ‘second’ or ‘thesis’. The point is to drive home the message that these words are not necessary, and that it is better to do without them.
Drive home the point that the introduction has successfully indicated what the thesis of the essay is, without using the word ‘thesis’ or phrases like ‘the thesis of this essay…’.
Discuss the improved impact of the introduction compared to the earlier example. Ask the audience if they can say why this introduction is better. Take suggestions from the audience.
Explain that a good essay does not give the impression of a gap between the essay and its author. Point out that introductions which include phrases such as ‘the topic of the essay is…’ or ‘the thesis of the essay is…’ do not generate an authentic tone because they give the impression of a gap between essay and author.
Make it clear that students will not be able to go away and write great introductions straight away. Emphasize the need to practice writing improved essay introductions.
At this stage in the presentation, explain that there are certain questions that frequently come up. Say that you will go through some of them. Read out the question in green. Throw the question out to the audience. After discussing audience suggestions, you can read the slide to the audience. Field any further questions.
