Drawing on evidence from a longitudinal study of Canadian children’s emotional experiences within the grade-school classroom, this book considers the nature and significance of such experiences for children’s development and well-being. Within the learning context of the classroom, the girls and boys share their experiences of self, emotional understandings, and social relations through interviews and social cognitive tasks. The chapters provide scholarly analysis and practical information for those who agree that emotions are paramount to children’s comprehensive development. The book concludes by describing the practical implications and applications of its findings for parents, teachers, and caretakers of children, including how to help children learn about and negotiate emotions in themselves and in their interactions with others.
