This paper addresses professionals involved in field based teacher education. The emphasis is upon the role of the student teacher supervisors. Current research on supervision is discussed as well as models of supervision, teacher effectiveness research, and systematic observation techniques. The outline of examples on models of supervision covers clinical supervision, counseling, and instructional supervision. An outline is also provided of competencies for student teachers as determined by research on teacher effectiveness. The outline of methods for observing student teachers includes event recording, duration recording, interval recording, and planned activity check recording, with examples given of recording techniques for each. It is noted that the use of systematic observation will lead to student teaching evaluations that can determine specific strengths, weaknesses, and improvements made during the student teaching experience.
