What makes people learn effectively? What can we do to promote more effective learning? Innumerable researchers have studied these questions, yet their findings tend to be fragmentary and disparate. This book aims to provide the big picture. Drawing on research from all sectors of education, the authors show how effective learning depends crucially on a few easily understood principles. These hold good regardless of the age or nature of the learner or the context in which the learner is working. The book explains those principles and how to apply them, showing in the process how to make the vision of an effective learning society a reality.
