There is a growing interest in education for sustainable development and the challenge of building equitable education systems in both rapidly developing and slowly developing economies. The OECD, for example, is interested in assessing the developments in education and their outcome through an expansion of the Program of International Student Assessment (PISA). Others are interested in educational technologies, open education resources and innovative approaches to learning as a way of responding to the growing demand for learning. This book explores both the challenge, cases of development and the implications of the developments captured for practice and policy. No one book can capture all that is happening, but this book is the best place to start such a journey. There is much for us all to do, as the concluding section on needed action makes clear, but we can be encouraged by some of the imaginative work this book documents.
