Understand the purpose of a conclusion paragraph. The essay's conclusion is your last chance to remind readers how the research in your paper has supported your thesis statement. The conclusion ties everything together and leaves the audience with the sense that a valid argument has been presented and supported by relevant research.
Reaffirm your thesis statement. A concluding paragraph is not the place to first introduce your thesis statement. That should be done in your introduction. However, it is important to restate your thesis in your conclusion. You want to remind the audience of the purpose of your paper. Do not repeat the thesis statement verbatim. Rephrase it in a new way while keeping the meaning of the original statement.
Go over the research from the body of your paper. In your conclusion, show the audience how the pieces of research fit together and work to support your thesis. Do not add completely new research to the concluding paragraph, but do reiterate the most important aspects of the research that your paper has already covered.
Leave the audience with something to think about. End your essay on a memorable note. For example, show the audience how your topic influences their everyday lives or is important globally. Create a challenging question that asks readers to think about the implications of your paper's argument. Use a provocative quote from a research source used in the essay that sums up a point you want the reader to understand.
