An evaluation study was made of a project which developed videocassette learning modules featuring outstanding vocational agriculture teachers illustrating their teaching methods. The two-fold purpose of the study was to determine what teaching characteristics were considered most important by students, and whether viewing the videotapes influenced the students' perceptions of selected teaching characteristics. Subjects were 24 agricultural education students divided evenly into experimental and control groups. The Teaching Appraisal Scale (TAS) was administered to the class prior to their division into groups. The TAS is designed to assess a teacher's possession of 20 selected teaching characteristics and their perceived value. The experimental group viewed three videotapes which had been developed for evaluation. The study found that the most highly valued teaching characteristics were: enthusiasm shown by the teacher for teaching; ability to explain clearly; and giving clear and precise directions. There were few measurable changes in ratings by the experimental group after viewing the tapes. Tables present information on pre- and post-test rankings of the selected teacher characteristics, and a comparison of the responses of the two groups. A list of the 20 characteristics on the TAS is included. (JD)
