A seminar is described in which systematic observation techniques were applied to lecturer training to make the supervisory element in microteaching more objective. The system provided a highly structured technique that the lecturers could use to systematise their discussion of microlectures or real lectures, either recorded on tape or live. Three parameters were "observed": non-verbal, verbal, and content aspects of lecturing. These categories were used after the trainees learned the system and could reliably code a lecture into these components. This information was then used by the trainer and trainee as data in analyzing a lecture. A small scale study is reported in which the attitude of the trainees to each of four treatments (systematic observation vs. conventional feedback and audio vs. closed circuit television augmented feedback) was measured. No significant difference was found between groups. A discussion of the reliability and validity of the system is appended. (DAG)
