To teach, we have to know more about the subject but also more about teaching. This book provides the most relevant theories about the science of teaching, through anecdotes, examples, and reflections on daily work in the classroom. Each tale of experience leads to practical knowledge, alongside its own theoretical abstraction from traditional teaching manuals, and proposes different strategies to use at home or in class—creative, active ideas, produced and verified in real situations and meant to be implemented rather than just read. The book is complemented by the online blog Ideas CreActivas. Teaching with creativity is teaching for change. Creativity helps people grow into original, flexible, initiating, confident risk-takers ready to tackle obstacles and problems that present themselves in their daily lives at school and elsewhere. The tools for innovation described in this book help develop the educational process and make better use of individual and group resources.
