The book brings together leading thinkers in spectrum theory, to demonstrate how it can be applied to improve teaching and learning in PE and coaching.Drawing on real-world research in schools and universities, the book considers the history of spectrum theory, and examines its significance across important areas such as physical education teacher education, sport pedagogy, teacher development, models such as Games Sense and Teaching Games for Understanding, skill acquisition and student learning and perception. Every chapter highlights the practical implications of research in real-world settings and considers how spectrum theory can enhance learning experiences.This book is invaluable reading for all pre-service and in-service school physical education teachers, sports coaches, school pedagogical leaders and college lecturers.
