For more than a decade, there has been growing interest and research on the pivotal role of emotions in educational settings. This ground-breaking handbook is the first to highlight this emerging field of research and to describe in detail the ways in which emotions affect learning and instruction in the classroom as well as students’ and teachers’ development and well-being. Informed by research from a number of related fields, the handbook includes four sections. Section I focuses on fundamental principles of emotion, including the interplay among emotion, cognition, and motivation, the regulation of emotion, and emotional intelligence. Section II examines emotions and emotion regulation in classroom settings, addressing specific emotions (enjoyment, interest, curiosity, pride, anxiety, confusion, shame, and boredom) as well as social-emotional learning programs. Section III highlights research on emotions in academic content domains (mathematics, science, and reading/writing), contextual factors (classroom, family, and culture), and teacher emotions. The final section examines the various methodological approaches to studying emotions in educational settings. With work from leading international experts across disciplines, this book synthesizes the latest research on emotions in education.
