Scholars have long questioned the impact of teacher education programmes. Persistent claims are that pre-service teachers have fixed ideas about pedagogy when they enter training and that they become enculturated once in the profession. Within physical education (PE), similar concerns have been raised with respect to ball games. Research suggests that pre-service PE teachers typically have substantial experience of ball sports and find it difficult to implement non-traditional ball games pedagogies when they enter schools. Against this background, the aim of the study is to explore how pre-service teachers recontextualise ball games as pedagogic discourse in their transitions from university to school placement. Bernstein's pedagogic device and pedagogic discourse are employed as the theoretical framework. The investigation focuses on a Swedish PETE programme and the participants are six pre-service teachers. The empirical material consists of written assessments, observations of the pre-service teachers' lessons during school placements, and individual interviews. Findings suggest that the pedagogic discourse of ball games at the university was aligned with course learning outcomes and included the need to communicate goals, adapt and modify teaching, and combine different approaches. The pedagogic discourse at school placement involved traditional ball games, minimal curriculum references, progression in two or three lessons, and inclusive, enjoyable lessons. Factors that regulated the discourse were: familiarity with the pupils; the conceptualizing of inclusive teaching; norms regarding ball games in PE; expectations of the pre-service teachers; and the framing of ball games education in PETE. Recontextualising rules highlight challenges in transitions related to ball games.
