Consider the question or topic on which your research paper is to be written, and the point which your paper will make regarding your topic. Consult your notes, research materials and any outlines you have made to help you decide the thesis of your research paper.
Set the context for the research paper by providing the reader with any necessary background information they need to understand your arguments.
Describe why your main idea is important enough to justify being the subject of your paper by writing several sentences which explore the implications and scope of your arguments, and what you achieve by proving them. Explore the importance of your paper within the topic as a whole and state why it is important for the reader to continue past the introduction into the main body of the paper itself.
Create a thesis statement by writing one or two sentences which respond to the assigned question by summarizing the main idea or argument which your paper is based upon. Include logical reasoning and emotional appeal to create credibility in your thesis statement.
