This chapter examines the nature of a socially critical physical education and the opportunities it provides for teachers and students to question and challenge assumptions about physical culture and take action to effect positive change. Physical education is a mandatory school subject for many young people around the world. It is a space that is experienced in a variety of ways, often depending on the pedagogies used and content selected by the teacher. As a growing literature base shows, it is a space that often reinforces a raft of racist, sexist, and ableist beliefs as well as normalising discriminatory practices and behaviours. The challenge becomes one of questioning how physical education can become a space that is empowering and enables young people to not only participate positively in human movement culture, but also ask critical questions about physical activity within their communities and challenge dominant discourses around body image, health, gender, and competition. We conclude the chapter by offering further suggestions about what future PE practice and curriculum could/should look like to strengthen the social justice agenda.
