Among the common requirements for receipt of a degree in the social sciences is the completion of a senior seminar in which a senior thesis or capstone project is produced. A number of educational goals have been proposed for this requirement: integrating the knowledge base supplied by the regular curriculum, contributing to students' future roles as informed citizens, and preparing for study in graduate programs, among others. However, few studies have empirically explored the substance of the senior seminars and capstones offered across a discipline or studied their organization, requirements, and pedagogy. In the present article, the authors describe the results of a survey of sociology and psychology departments in the western United States regarding their senior seminar and capstone courses.
