In this paper I explore how I have come to theorise my work as a critical emancipatory practice as a lecturer in primary physical education (PE). I give an account of what I understand to be the epistemological foundations and practices of practitioner research and my potential educational influence in my own and other practitioner-researchers' learning. I explain how I have generated my living educational theory of practice and discuss the changes in my learning from a propositional approach towards a dynamic epistemology of practice that is grounded in inclusional and dialogical ways of knowing. Within my paper I position myself as a professional educator and researcher, and share the exciting and transformational experiences of teaching and learning in evolving action research cycles of practice. I view my learning to date as an active act, working with the novice teachers I support to offer improvement and change in our future practice. I celebrate my reconceptualised view of education as a learner from within my practice and explain my move from knowledge transfer to knowledge co-creation. I make an original contribution to educational knowledge by explaining how I try to inspire others to research their practice and contribute to a new scholarship of educational enquiry.
