This is a collaborative product from a series of workshops for teacher educators who supervise the teaching practicum of student teachers. Through the open interflow of experiences, the authors of the chapters reached further understanding of the intentions and the impact of their supervisory practice on student teachers’ learning. The book is intended for teacher educators, senior teachers and principals in schools who are involved in induction of new teachers or staff development. Though the issues discussed are situated in the Hong Kong setting, the underlying themes are of general relevance to all who are concerned with the professional development of teachers and the meanings of collaboration in the process.
