In the simplest terms, a thesis paper is an academic research paper built around a strong thesis statement. Depending on the subject, the thesis either is a new interpretation of existing research on the subject, or based on original research conducted by the student combined with existing knowledge in the field. For example, an undergraduate media studies student may choose to research the portrayal of a certain demographic on television, and conduct a content analysis of several programs to compare the current state of television to existing conclusions.
The purpose of a thesis paper is to provide an opportunity for students to apply the knowledge they have gained in their college coursework while simultaneously expanding their knowledge via research. It’s not a “typical” research paper; it’s much longer, for starters, with specific formatting requirements. In addition, students are generally required to present and defend their research to a thesis committee, who may ask for revisions before accepting and grading the project.
