This paper describes the teaching skills workshops at Purdue University (Indiana), which were originally developed in 1980 to train graduate assistants to teach college classes but are now being used by the faculty--instructors through full professors--to improve their teaching. It is noted that the workshops have been successfully modified for use with different audiences and under varying time constraints. This description provides brief descriptions of the 10 90-minute sessions that are offered: (1) Student-Teacher Relationships; (2) University Policies and Procedures Related to Teaching; (3) Designing Instruction; (4) Lecturing Techniques; (5) Audio-Visual Techniques; (6) Micro-Teaching Exercise; (7) Discussion Techniques; (8) Developing Tests; (9) Scoring Tests and Assigning Grades; and (10) Evaluation Instruction. Four primary techniques for advertising the workshops are described, i.e., the CIS Newsletter, the university channel on the local cable television system, direct mail, and word of mouth. Procedures and materials used in conducting the workshops are discussed, and five methods used to evaluate the workshops are listed: verbal comments by participants, session evaluation forms, course and instruction evaluation (Likert-type items with statements about the instructors, materials, media, and content), small group instructional diagnosis, and an open-ended rating scale. Also described are follow-up activities, formal reviews of the workshops, and modification of individual workshops to meet specific needs and requests. Copies of the continuity sheet for workshop facilitators, the session evaluation form, and the small group instructional diagnosis form are appended. (6 references) (BBM)
