As a teacher and mother of two teenagers I am always looking for educational recipes! This book is a synthesis of several non-violent educational movements and learning aids. The ideas are very interesting but their applications are perhaps more difficult with adolescents with toddlers. I also try to circulate with my fellow teachers, but the rigidity of education in France (despite the failure of our system observation) leaves little hope of change. However, I diffuse the positive message of this book and opts for "hummingbird strategy"; Thank you to their authors!
