The catalyst for this self-study was implementing peer-teaching in our respective science education and physical education teacher education courses. Because our students taught one another it meant we redefined our roles as teacher educators as well as the roles that our students took in the teaching and learning community. We documented and explored our learning about teaching and teacher education through journaling, observations, discussions and interviews with students. Our students' responses to peer-teaching provided a critical lens through which we considered our efficacy as teacher educators. Through this collaborative self-study, we have learnt to manage the issues of authenticity and safety for ourselves and our students.
