Open your word processing program or take a blank sheet of paper and pen, and write down your original question or thesis statement.
Read your notes and outline your report. The outline should include the original thesis statement or question, your conclusion, and should be divided into at least four sections including "introduction," "beginning," "middle" and "conclusion."
Write two to three things you have learned in relation to your research. State them in your own words, without looking at your notes or outline. List two to three opinions you have on the subject. Define the conclusion you have reached in one sentence. This is not yet your introduction, these are only basic ideas that you might include in your introduction.
Write your opening line. The opening line should include information about the topic, and should relate to the question that led to the research.
Add the things you have learned and your opinions related to the subject. Add your conclusion.
Re-read your introduction, and where necessary, edit. Your introductory paragraph should clearly state the purpose of the research paper, the original thesis statement, and demonstrate your knowledge of the subject. It should also be grammatical, and correctly spelled.
