Abstract
Physical education teacher educators' health-related beliefs can impact public health. An interactive knowledge-to-action approach, such as Cooperative Planning, might challenge the health-related beliefs of physical education teacher educators, thus contributing to innovation in teacher education. We investigated what health-related beliefs physical education teacher educators had before a Cooperative Planning intervention, how these developed throughout the intervention and how teacher educators' perceptions of Cooperative Planning can explain the identified changes and continuities. We established two Cooperative Planning groups that included physical education teacher educators (university lecturers and teacher trainers), researchers, study course coordinators and prospective teachers. The data of 13 teacher educators were collected before (t0) and after (t1) the Cooperative Planning using two methods: observations of teaching practice and interviews. The data analysis was based on the following categories: (i) epistemic beliefs about health (e.g. salutogenic understanding), (ii) beliefs about the health topic in physical education (e.g. health-related knowledge and understanding), (iii) beliefs about the health topic in physical education teacher education (e.g. health-related pedagogical content knowledge) and (iv) process-related beliefs about Cooperative Planning. The findings revealed that teacher educators' health-related beliefs were rather stable but could be challenged through a Cooperative Planning intervention. Epistemic beliefs about health remained, whereas more practice-related beliefs about the health topic in physical education and physical education teacher education changed in individual ways. Here, a change in beliefs was more likely when the participants were open to change and when Cooperative Planning offered opportunities to engage in concrete lesson planning.
