This book is the result of collaboration by scholars in developmental psychology and educational sciences from six European Countries (Austria, Denmark, France, Germany, Switzerland, and the United Kingdom) and Canada and the 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 not only acquire an understanding of emotions in learning but also propositions for interventions that seek to help children, adolescents (pupils, students) and adults (teachers) to improve their emotional experiences and comprehensions in the context of learning and teaching.
