$125,000 over 36 months to scale up the work of the GSI Teaching and Resource Center pilot program significantly, integrating research on student learning and its application more fully into Berkeley's programs for preparing graduate student instructors for current and future teaching. Where the pilot program reached 75 students directly and 810 indirectly, the scaled up program will reach 532 directly and 14,400 indirectly. Among the strategies for developing and delivering the enhanced program will require first-time graduate student instructors to take a one semester, discipline-based course on teaching. The GSI Teaching Center will identify 8 departments in 2012 and another 8 departments in 2013 that would like to integrate into their required course a module on how students learn, and design a seminar for the instructors of those courses who can then integrate the module into their teaching. Program assessment will take multiple forms, and results will be disseminated widely.
