One writes a Ph D thesis as the crowning project before receiving a doctoral degree, and it usually represents the most strenuous, the deepest, and the most significant work of one's academic career. Because of the depth of research and thought necessary to produce a good Ph D thesis, one becomes an expert in that subject and often goes on to teach that subject at the university level. . . . .
In a synthesis essay, one performs research on a selected topic and writes an essay that weaves the research sources together to form a coherent unit of thought. Synthesis essays may or may not make a persuasive argument; in either case, their primary goal is to show the writer's ability to read many different research sources and to fit them together to present the reader with a unique body of information. . . . .
Because a thesis is in essence a research dialogue between previous researchers and the student, who develops a new perspective for the discussion, example theses may provide some excellent feedback and food for thought for the student writer. They may help the student think more critically about different perspectives on the subject of the thesis, about other research, and about writing and argumentation. Because one can find example theses online in such abundance, they may especially provide good inductive information for the student who is honing his or her project. . . . .
Literature reviews provide an invaluable service for academia because they perform the function of the peer review, in which one expert in the field analyzes the work of another expert and evaluates the validity and reputability of that work. This function allows people who know less about the field to feel comfortable trusting or ignoring major works of literature based on the reviewer's educated, disinterested opinion. . . . .
The best thesis is a project that combines an innovative idea; exhaustive, creative research; and strong argumentation to produce a work that adds something memorable to the target discipline and that convinces its readers of its point. . . . .
