In Physical Education (PE), as well as in several other school subjects, the content knowledge has been proven to be reproduced through strong subject traditions. In PE, this reproduction has promoted children who are already privileged in school and society. In this paper, explanations to the difficulties of influencing subject traditions in PE are searched within Physical Education Teacher Education (PETE). Learning objectives stipulated in curricula documents within teacher training courses at six Swedish PETE institutions have been investigated. The preliminary results of the study indicate that the learning objectives expressed appear to reproduce the dominance of (natural) scientific and behaviouristic traditions in PETE and a dualistic approach to PE teacher knowledge. These results will be discussed in relation to theories of teacher knowledge. Exploring learning objectives within PETE may be of significance for the construction of PE knowledge at a school level and may also offer explanations to the promotion and marginalisation of children in PE teaching.
