Research that led to the development of an instrument and a program for collecting students' evaluations of college/university teaching is summarized. The current version of Students' Evaluation of Educational Quality (SEEQ), which is appended, was developed at the University of Southern California (USC). (The first SEEQ was developed at the University of California, Los Angeles.) The one-page evaluation instrument contains standardized questions, allows for an individual instructor or academic unit to design items, and provides for student comments to open-ended questions. Research indicates that SEEQ measures nine distinct components of teaching effectiveness that have been identified in both student ratings and faculty self-evaluations of their own teaching. Reliability is good when based upon 10 to 15 or more student responses. The ratings have successfully been validated against the retrospective ratings of former students, student learning as measured by objective examination, affective course consequences, and faculty self-evaluations of their own teaching effectiveness. Feedback from student ratings, particularly when coupled with a candid discussion with an external consultant, produced improvement in both subsequent ratings and student learning. Data derived from factor analysis, a sample summary report returned to individual faculty and department heads, and references are included. (SW)
