This book is the result of the collaboration by scholars in developmental psychology and educational sciences from Europe (Austria, Denmark, France, Germany, Switzerland, and United Kingdom) and North America (Canada and United States). It provides an overview of innovative research on emotions in learning from a psychological and pedagogical point of view. Indeed, emotions have recently emerged as one of the main factors of learning. With this book, the reader will get not only an understanding of emotions in learning but also propositions for interventions seeking to help children, adolescents (pupils, students) and adults (teachers) to improve their emotional experiences and comprehensions in the context of learning and teaching.
