There are increasingly more at-risk children and students with disabilities to manage and physical activity professionals also face the unique challenge of providing instruction to large groups with limited resources and distractions galore. This resource will help overcome these and other discipline challenges, but also uses tried-and-tested, positive techniques to develop appropriate and responsible behaviours, and good character among all learners. This new edition incorporates principles, methods and instructional practices from psychology, special education, pedagogy, recreation, athletics and coaching. It shows teachers, coaches and recreation leaders how to apply the principles that have proved effective in schools and youth sport programmes.
