Writing an introduction

The introduction answers the questions:

The introduction

The structure of the introduction can be thought of as an inverted triangle - the broadest part at the top representing the most general information and focusing down to the specific problem you studied. Organize the information to present the more general aspects of the topic early in the introduction, then narrow toward the more specific topical information that provides context, finally arriving at your thesis statement.

For long introductions give the reader already an indication earlier of what question you'll be addressing.

Be sure to include a hook at the beginning of the introduction. This is a statement of something sufficiently interesting to motivate your reader to read the rest of the paper, it is an important/interesting scientific problem that your paper either solves or addresses. You should draw the reader in and make them want to read the rest of the paper.

It can be useful to sketch out the introduction backwards, start with the specific focus of your study and work upward to the broader context. It is hard to write a good introduction until you know what the body of the paper says. Consider making a concept map, it will help to identify the elements you need in the introduction.

You can break up the introduction section into logical segments by using subheads.
