In an attempt to devise protocols for the microteaching of university teachers, an experiment was undertaken using 15 subjects in four training sessions. Attitudes of lecturers to training were used as the dependent variable. Independent variables were the feedback medium (CCTV and audio) and the type of feedback (low and high structure). The feedback type relates to systematic observation to describe and analyse lecturing. This high structure technique was used in opposition to the normal microteaching supervisor low structure practice of non-directive sessions. Due to the smallness of the factorial cell size, no statistical treatment of the data was possible; however, available data suggest no observable difference between treatments. (Author/DAG)
