Though a small number of research papers have sought to document this occurrence, they appear to have fallen some way short of capturing the complexity of the educational landscape. Using an applied theoretical framework from complexity theory, a number of specific insights are highlighted. The paper concludes by suggesting that the UK finds itself at a pivotal point in the pedagogical future of primary physical education.
