Selected findings from a major investigation of preservice clinical teacher education are presented, focusing on the supervision of 20 student teachers by their cooperating teachers. Participants completed background questionnaires, responded to five evaluation questionnaires, kept journals, audiotaped their supervisory conferences, and participated in interviews. They were also observed in their classrooms periodically over the semester. A summary is presented of the analysis of both quantitative and qualitative data gathered in the study, and a description is provided of supervisory conferences conducted by students and cooperating teachers. Findings and conclusions which focus on the supervision and feedback interactions between the student teacher and the cooperating teacher were extracted from three case studies. Conferences appeared to be dominated by the cooperating teachers, and most talk was classified as comment which dealt with classroom events or student teaching activities. Participants tended to discuss teaching rather than the organization of student teaching, or subjects that were outside the teaching realm. Recommendations are made for further research on supervision of student teachers. (JD)
