The QCA's PE and School Sport website contains a wealth of resources and case studies for anyone with an interest in the role of physical education within schools. The most recent DfES-commissioned annual School Sport Survey is also available online.
If you'd like to delve a little deeper into this topic, then sportdevelopment.info has an incredible amount of full-text material on its website, much of which is relevant for people working with children. Or if this all sounds too energetic, sit back and choose from a selection of nearly 50 programmes about various aspects of physical education which can be viewed on the Teachers TV website.
