Courses

Guides graduate student preparation of an acceptable master's thesis or PhD dissertation proposal in a series of papers and in-class oral presentations. Students work with a thesis advisor and committee within a framework defined by the instructor to define a thesis problem in terms of relevant literature and design a research plan, including a support budget. In the process, students are expected to improve their skills in literature research, writing, and oral presentations.

Research for and preparation of doctoral dissertation proposal. The dissertation proposal must provide a thorough survey of the research activities in the research topic area and it must present original and innovative research ideas and preliminary results as well as a defined research scope and directions. PhD students must have passed this course before registering for doctoral dissertation research credits. Graded P/F.
