Typical of postgraduate courses for experienced teachers is the wealth of professional experience that the students bring with them. Such students can examine their own practice, for which they are fully responsible. Postgraduate programmes are, therefore, challenged to create a flexible and research-led infrastructure that can respond to developments in the educational field and relate these developments to educational, philosophical, conceptual, and moral issues. Through the creation of a platform for such activities, the professional development of postgraduate students can be enriched. Authors from diverse backgrounds address important aspects of the platform, such as the relation between tutors and students; teachers' professional identity; the voice of pupils; the characteristics of teachers' workplace of the participating professionals; the relationship between action research and teacher leadership. This book offers inspiring and thought-provoking ideas to all involved in postgraduate programmes in teacher education: teacher educators, policy-makers, researchers, administrators, and schools collaborating with staff of postgraduate courses and their students. The book is an initiative of the Research Group 'Interactive Professionalism and Knowledge Development' at Fontys University of Applied Sciences, Department of Inclusive and Special Education, The Netherlands.
