This text is topical internationally in studying the role, functions and effectiveness of the university/college supervisor in the over-seeing and training of the beginner teacher for the classroom. This is particularly significant for those countries introducing teacher-mentor schemes which automatically reduce the job of the HEI supervisor. This book starts to make some headway by defining the role of the external supervisor more clearly. Using case studies of actual supervisors, this text identifies the different roles of the supervisor and co-operating teacher in preparing the student.
