The materials, methods, and mechanisms that underlie the learning and performance of motor skills are explored. This booklet focuses on concepts which can be used to enhance student learning and performance in physical education. The chapters consider such questions as, "What types of skills will I learn?", "Should I practice different skills in different ways?", and "How can I use feedback to improve performance?". Suggestions are made for how performance might be evaluated to trace student improvement. The final chapter summarizes the major changes that take place as learning occurs. (JD)
