Two methods to improve the teaching performance of clinical teaching physicians were studied: an intensive feedback method and a seminar. Both methods were designed to help clinical teachers analyze their teaching and implement more effective teaching methods. Pre- and post-intervention data were collected early and late in each attending physician's 1-month teaching rotation. In addition to considering clinical teachers' evaluation of the methods and teacher self-assessments, feedback was provided by student and housestaff ratings of the teachers, and videotape ratings of actual clinical instruction made by trained raters. Comparisons were made to teachers who only received written feedback from students and housestaff. The seminar method presented specific examples of clinical teaching, including viewing re-enacted videotapes of clinical rounds. The method also facilitated discussion of videotapes, teacher's review of student and housestaff ratings compared to self-ratings, and teacher's identification of desired teaching changes. Research results indicate that effective methods of improving clinical teaching can be developed. Five recommendations for use of the methods are offered, including providing educational tools/concepts applicable to the teaching setting. (SW)
