The way that you structure an argumentative essay is based on the same basic principles as structuring a short composition.

a) Introduction contains any background information, hook etc. It should introduce the topic and (at the end) clearly state your thesis statement.

b) The discussion / body is where you present your evidence to support your thesis statement. As a general rule, each piece of evidence should form a paragraph, and have enough detail to show that it is both accurate and authoritative.

c) The conclusion reminds the reader of your main evidence, and then restates your thesis statement in different words.

In a longer composition (500 words), the introduction and conclusion will be very similar to the short composition, the only difference being that you may need to add a definition of an important word, or more information about the choice of your topic in the introduction. Remember, the conclusion is not just one sentence that repeats your thesis statement – you must provide a short summary of your most important points.

The most important difference between a short and longer composition is in the quality and quantity of evidence, and in the way in which it is arranged.

Evidence should be arranged carefully, in the way that best proves your point. The way that evidence is best arranged will vary depending on the topic and type of evidence. Generally speaking, you need to arrange the evidence in a format that is consistent – for example according to time, or from least important to most important, most familiar to least familiar etc. Look at your own evidence, and think carefully about the order. Is there any evidence which fits naturally together? Does any evidence rely on the existence of other evidence? Once you have decided these points, you can consider the order in which you will present your argument.

It is generally better to deal with counter-evidence before you set out your own evidence. The reason is that a composition is usually arranged climatically – the climax, or most memorable moment, comes at the end. Therefore, it is better to deal with counter-evidence first, and then focus on your own argument.

Proportion is another important factor in a composition. You need to keep a balance between your introduction, discussion and conclusion. The introduction and conclusion should not be more than…

In an exam, you have no opportunity to gather evidence from other sources except what you remember in your own head, but in an assignment, sources are very important, because they help to show that your evidence is authoritative. Copying without giving credit to the source is plagiarism, it is theft, and it is always unacceptable.
