In this fascinating and very personal book, Jean McNiff argues that educational knowledge is created by individual teachers as they attempt to express their own values in their professional lives. Working with case studies she looks again at the familiar action research model of identifying a problem, devising, implementing and evaluating a solution and modifying practice in the light of that evaluation. She gives practical advice on how working in this way can aid the professional development of action researcher and practitioner alike. The best teaching, McNiff concludes, is done by those who want to learn and who can show others how to be open to their own processes of self development.
