Procedures are described which were used in a short microteaching period in a Postgraduate Certificate in Education Program in the United Kingdom. In this program, a tutor works with groups of 15 students who have already had at least 2 years of teaching experience. The program of 7 days is divided as follows: (1) all 15 students teach one lesson, with a short discussion period; (2) videotaped lessons by 15 students with selective play-back and discussion; (3) group preparation and presentation of a segment of a lesson, with discussion; and (4) student-determined closure. In this program, the tasks are predetermined and the students select and adapt those they are going to work on. In practice, four sets of students are involved in any particular lesson, teaching or observing or doing the technical camera work. All the students are involved in the discussion which generally exceeds the time-limits of the class time allotment. In addition to the description of the program, several comments are included regarding the student-teachers, difficulties involved in simulating student behavior, camera operation, techniques for observation of the videotape lesson, the role of the tutor, and the problem of achieving a balance between praise and negativity.
