In recent years there has been an increasing demand for accountability and evaluation of teachers. One nonthreatening method that might be used by teachers to evaluate and improve their classroom performance is self-appraisal. The experiment in this document uses the Teacher Self Appraisal (TSA) observation system which divides the teaching act into three categories: (a) methods, (b) objectives, and (c) expressions. By video taping classes and using these categories, it was hoped that the teacher would be able to recognize deficiencies and improve performance. Six tapings were made at two-week intervals, and after each session the tape was viewed and analyzed. Stops were made at 15 second intervals, and the teacher determined what was going on according to the above categories. The tape was then analyzed in terms of the teacher's goals for the class. In this particular case, the teacher was able to identify various deficiencies and problems after viewing the tapes. By the time the last tape was finished (and after much effort towards self-improvement on the part of the teacher) a definite improvement was obvious. (Appendixes describe the TSA observation system and contain a sample work sheet and results of the video taping.) (PB)
