Write to your audience. The most crucial aspect in writing a paper is the audience reading the paper. Some things that are imperative to consider are age range, type of reader and education level. If the target audience of your paper is a group of elementary school children, you need to write your introduction so it is easy for them to understand, which is not the same type of writing a group of academic scholars expect to read.
Outline the introduction before writing it. Listing your thoughts, points and thesis statement helps you to see the information and choose how you want to arrange it to make it most effective to your readers.
Start your introduction with your argument. Broad statements only add fluff to your writing. Starting with a bang helps capture the attention of your target audience. Try stating a lesser-known fact about the argument you are making in your paper.
Write your thesis statement. This needs to be a clear statement at the end of your introduction that states the position you are taking on the subject you are writing about. Your thesis should encompass exactly how your paper discusses the topic at hand in an educated, concise manner.
Avoid useless information and fluff. Adding broad sentences that do not reflect the thesis or theme of your paper just to make your introduction longer only makes your introduction seem disorganized and unfocused.
Read your introduction aloud to a friend or family member. Hearing yourself speak the introduction and having the opinion of someone else helps you identify points that need work, or information that is unclear and in need of a revision.
