In response to the need for better trained teaching assistants to serve a growing undergraduate population, this project established a campus-wide Teaching Assistant Development Program (TADP) at the University of California Riverside. Project efforts included inviting departmental participation in shaping teaching assistant (TA) seminar content; focusing seminars on "practical" instructional, testing and grading techniques; developing three "disciplinary cluster" seminars; fostering cooperative TA-faculty relations in the seminar's content; and inviting departments to develop their own TA training programs. In addition the project actively promoted TADP services and benefits in meetings with departments, in publications and memos, as well as successfully courting the campus press for favorable coverage of its events and services. Project results included public accolades from top administrators, funding for additional equipment for the next fiscal year, heightened campus commitment to teaching, reduced numbers of low-evaluated (problematic) TAs by 33 percent, and improved student ratings of first- and second-year TAs. In addition the project compiled a book of readings from other TA handbooks and newsletters and published an original TA handbook and a quarterly TA newsletter. Extensive appendixes contain correspondence and memos from the project, event announcements, evaluation forms, student evaluations, three issues of a TA newsletter, the Tadpole, and a quarter report for fall 1989.
