The invitation to serve as Minister of Education and lead a bold and significant reform of an education system never comes with an instruction manual. Leading such an opportunity effectively, requires access to the best knowledge about how to make change happen. In this book, Ministers of Education and system level leaders in fifteen countries share what they learned in the process of advancing audacious reforms aimed at transforming public education so schools would better prepare students with the necessary skills to participate civically and economically in a rapidly changing world. A product of the Global Education Innovation Initiative, a practice-research consortium of leaders and institutions that advance knowledge to support the transformation of public education systems to augment their relevancy, the book is anchored in the proposition that successful educational change requires the appropriate combination of knowledge based on practice with knowledge based on research. The contributors to this volume embody the best qualities of reflective practitioners who can make visible what they have learned from their practice. In sharing with what they have learned with others, they demonstrate also the generosity and commitment of those who understand that we all share responsibility for the education of the entirety of the world's children. In this book, the reader will find discerning and intimate accounts of what it is like to transform the largest organization in society, so it does a better job educating all children. The themes that resonate in their accounts across systems as diverse as Australia, Brazil, Colombia, Ghana, India, Liberia, Mexico, Peru, Poland, Portugal, Russia, Singapore, South Africa and Yemen are fascinating, surprising and valuable to those who hope to leave a legacy as Ministers of Education.
