The conclusion chapter of a thesis briefly reviews the thesis's whole argument in order to solidify it in the reader's mind. Because the conclusion chapter represents the writer's last chance to convince the reader of the thesis's perspective, the writer should use excellent rhetorical and analytical skills and should spare no effort in polishing the writing.
First, the writer should make sure to mention every major point of the thesis. In order to do this well, he or she may refer to the chapter titles and the major subheadings and devote a paragraph or a couple of pages to each one. The writer may consider including the principal pieces of evidence under each point, if space allows and if they would strengthen the rhetorical effect of the conclusion chapter.
Second, because conclusion chapters cover a large amount of material very quickly, using appropriate transitional phrases is key. The writer should be careful to use phrases that accurately reflect the course of the argument; for example, when moving to a new point in the discussion, the writer should not use the phrase "on the other hand" when the argument actually requires the use of "additionally" or "furthermore." While using the correct transitional phrase may seem like an insignificant detail, in reality the transitions drive the rhetorical effect of the chapter and tell the reader how to fit the pieces of the argument together. Students who pay close attention to the transitional phrases they use will improve their conclusion chapters noticeably.
Third, the writer should carefully edit the conclusion chapter for proper grammar and for the correct meaning of the sentences. Students who have used unfamiliar words should look them up in the dictionary to make certain that they are using them correctly. Moreover, students should compare the conclusion chapters against the arguments that their theses make and should resolve any discrepancies.
Conclusion chapters should showcase the student's best possible writing. If students need additional help in verifying the quality of their writing or rhetorical skills, they should contact their instructors, their classmates, or an editing service.
