This booklet examines the instructional practice of modeling and describes step-by-step techniques for learning to use modeling to improve or modify teaching. The authors discuss the possible use of audio and videotape equipment and emphasize the importance of constructive feedback and individual practice sessions as essential parts of the modeling process. In addition, the authors show how these techniques might be incorporated into a program of performance-based supervision for use during preservice and inservice teacher training. (JG)
