Many experiences in physical education class focus around competitive activities. Middle school is an important time for students, as they shape their physical identity. Creating a foundation of skill during these activities, may promote a lifetime of future physical behaviors. Therefore, attaining physical skill can create social capital, ultimately a form of social justice, as individuals may use this foundation to be physically active throughout their lives. During middle school, however, physical activity declines. This decrease in physical activity, perhaps, limits physical possibilities later in life. To examine this injustice, the term "skill identity" has been created. Skill identity acts as a new lens for educators to reflect on their practice. The following will be discussed: a) competitive activities and physical education class (skill, identity, and social justice and injustice), and b) identity, social capital, and justice (creating strong or weak skill identities, the teacher, and gender and race).
