Practical, accessible and up-to-date, this book draws directly on the work of teachers and other professional trainers concerned with programs for continuing professional development. It promotes action research for practitioners to develop qualities of critical appraisal and analysis of practice, appropriate to professional contexts. The authors suggest activities and give support for teaching, and evaluation of teaching, by using actual examples of teacher research into professional issues. They also aim to encourage teachers' narrative writing and autobiographical approaches to researching their professional lives. There is a specific focus on processes of professional development, which connects with current needs, demands, and challenges of the modernized profession. This book will support those involved in appraisal activity, performance management and threshold application.
