Start with a question — then make the answer your thesis. Regardless of how complicated the subject is, almost any thesis can be constructed by answering a question. Question: «What are the benefits of using computers in a fourth-grade classroom? Question: «Why is the Mississippi River so important in Mark Twain’s Huckleberry Finn? Thesis: «The river comes to symbolize both division and progress, as it separates our characters and country while still providing the best chance for Huck and Jim to get to know one another.
Question: «Why do people seem to get angry at vegans, feminists, and other «morally righteous» subgroups? Thesis: «Through careful sociological study, we’ve found that people naturally assume that «morally righteous» people look down on them as «inferior,» causing anger and conflict where there generally is none. Tailor your thesis to the type of paper you’re writing. Not all essays persuade, and not all essays teach.
