The book takes an original approach to the question of curriculum change in physical education, building on increasing interest in historical research in the field of curriculum studies. It adopts a social constructionist perspective, arguing that change occurs through the active involvement of competing groups in struggles over limited material and ideological (discursive) resources. It also draws on contemporary developments in social and cultural theory, particularly the concepts of discourse and ideological hegemony, to explain how the meaning of physical education has been constructed, and how particular definitions of the subject have become orthodoxes. The book presents new historical evidence from a period which had previously been neglected by researchers, despite the fact that 1945 marked a watershed in the development of the understanding and teaching of physical education in schools.
