Educators have already taken on board the idea that educational change and school reform are not as easy to accomplish as first expected. In this book, Michael Fullan, arguably one of the world's leading authors on the issue of educational change, explores why this continues to be the case, and builds on the lessons that he set out so clearly in the first two volumes of his trilogy on the subject. This book is concise, accessible, and the message contained is clearly written with a broad audience mind both for academics in education and general reader.
