The need for outstanding university supervisors who balance the needs and interests of the student teacher, the university, and the K-12 school has never been greater. Teacher supervisors are the link between institutions of higher learning and public and private schools. This work is a practical guide for university supervisors that examines the supervisory process, the preparation necessary for supervision, the responsibilities of the university supervisor, the historical assumption underlaying the supervisory role, and what research tells us about effective supervision. This work also provides background information on topics such as discipline in the schools and curricular concerns, and summarizes research about what the supervisor needs to know on the philosophical, psychological and sociological foundations of education. Practical suggestions and sound advice are provided on major questions and issues such as: What should I tell the co-operating teacher about writing final evaluations? What should I tell the student teacher about presenting incorrect information? What do I look for while observing the student teachers? How do I conduct an effective conference? How should I plan a seminar? University supervisors may gain a better understanding of their own role and responsibilities in working with student and co-operating teachers as well as an appreciation of the work of the co-operating teacher. Likewise, student and co-operating teachers may gain similar understandings.
