This volume of the International Handbook of Educational Change deals with the idea and necessity of extending change - conceptually and in action. Extending educational change means making existing approaches to educational change work more effectively in more places and deepening our understanding sensitivity to those whose interests are at stake. Who benefits and who loses? How do these interests and how we address them affect what kinds of changes we pursue? What challenges does all this pose for the change process itself? Like other volumes in the series this book brings together evidence and insights on educational change issues from leading writers and researchers in the field from across the world.
