Beware of the temptation to open your final paragraph with "In conclusion," or "In summary," and then summarize the paper. Instead, let your entire conclusion stand as a graceful termination of an argument. As you write your conclusion, concentrate on presenting the bottom line, and think of the word’s definition: a conclusion is an articulated conviction arrived at on the basis of the evidence you have presented.
Most papers have outright thesis statements or objectives. Normally you will not devote a separate section of the paper to this; in fact, often the thesis or objective is conveniently located either right at the beginning or right at the end of the Introduction. A good thesis statement fits only the paper in which it appears. Thesis statements usually forecast the paper’s content, present the paper’s fundamental hypothesis, or even suggest that the paper is an argument for a particular way of thinking about a topic. Avoid the purely mechanical act of writing statements like "The first topic covered in this paper is x. The second topic covered is y. The third topic is . . ." Instead, concretely announce the most important elements of your topic and suggest your fundamental approach—even point us toward the paper’s conclusion if you can.
Here are two carefully focused and thoughtfully worded thesis statements, both of which appeared at the ends of introductory paragraphs:
Of course, papers should always be typed, double-spaced on 8-1/2 x 11 paper on one side of the page only, and letter-quality print or better is always expected. Often you are expected to supply a cover sheet giving the date, your name, the title of the paper, the class, and the professor’s name. Tables and figures should be numbered consecutively throughout the text, and if there are a good number of them, then separate lists of tables and figures at the beginning of the paper may be expected. Tables and figures should always have descriptive captions, and if they come directly from sources, the sources must be specifically credited in the captions with the same citation style that you use throughout the paper.
