This book explores the importance of social and emotional learning (SEL) in schools to foster supportive environments and good relationships. It presents research from nine different countries with discussion of how teachers, student teachers and policymakers can ensure successful SEL at school. The book stresses the importance of social and emotional learning to allow students to become more autonomous and active in their own learning and presents very innovative ways of learning and teaching the skills. It makes the case for understanding the processes of how SEL can develop and how it can work in different cultural contexts, considering different challenges of implementing SEL within the school context. The chapters draw on theoretical discussions illustrated by practical examples and explore the role of teacher training in SEL and how SEL can be applied within the school curriculum.
