How to write an introduction

In the example introduction above, background information is given in the first sentence. This builds context for the essay’s main topic and eases the reader into the topic statement. The background statement can be one or more sentences, depending on the overall word length and complexity of your assignment.

The topic sentence in the example above is:

“The continued growth in the number of people living and working in the major population centres leads to the question of whether or not Australia should invest in a high-speed rail network.”

• Notice that this looks very similar to the assignment question. A good topic sentence paraphrases the assignment question to demonstrate to the marker that you are answering the question that has been asked. It should also logically lead the reader to the thesis statement.
• An easy way to make your topic sentence clear to the reader is to begin the sentence with: “The purpose of this paper is to discuss/critically examine/analyse….”

The thesis statement is the writer’s answer to the assignment question in one sentence. In the example above, the thesis has been expressed in the following sentence:

"This paper argues that a high-speed rail network between major Australian cities should be developed."

• Although many assignments require you to take a position (or give an opinion) on a topic, some may only require a summary or an analysis of the literature. In such cases, a thesis statement is not needed.
• Because a thesis statement involves giving an opinion, it will always be an “arguable” point, which means that other people may have a different opinion. The purpose of the assignment is to use evidence and logical reasoning to convince the reader that your position on the topic is valid.
• An easy way to make your thesis statement clear to the reader is to begin the sentence with: “This paper/essay/report will argue that ….”

An outline is a summary of the main points of the writer’s argument or topic and acts to inform the reader of what to expect in the body. In the example above, the following two sentences form the outline:

“This essay will firstly examine the history of the proposal to develop high speed rail between Sydney and Melbourne. It will then outline some of the political, economic and environmental challenges that have prevented this endeavour from progressing in the past, before finally discussing the significant advantages that such infrastructure would provide for Australia.”

The outline is important because it helps the reader know what to expect as they read your assignment. This means they can focus on your ideas rather than trying to work out where you are going with your discussion.  If you change your structure as you are writing, always double check your introduction to make sure they match.

Think of the introduction and conclusion as bookends, keeping the ideas in your assignment together.  In your conclusion you can summarise your main argument (or thesis), along with the key issues you raised in the background section of the introduction.
