Signature pedagogies [Shulman, L. 2005. "Signature pedagogies in the professions." "Daedalus" 134 (3): 52--59.] are a focus of teacher educators seeking to improve teaching and teacher education. The purpose of this paper is to present a preliminary common language of signature pedagogies for teacher professional development (PD). In all, 24 papers from the study of physical education PD projects with clearly articulated pedagogical objectives and documentation on achieving those objectives were included in the analysis. In total 479 teachers and 48 facilitators across the US and Europe were interviewed and/or surveyed. Three discrete PD signature pedagogies holding potential to enhance teacher growth and learning within the context of PD were identified: critical dialogue (process of acquiring knowledge through communicative interactions), public sharing of work (testing out practices in classrooms and share ideas with larger audiences), and communities of learners (collective learning around a shared concern or a passion). It is our hope in providing the beginnings of a common vocabulary for pedagogies of teacher professional learning we have encouraged additional steps toward developing signature pedagogies for learning across different PD settings and content areas.
