This chapter provides an account, from the perspective of one of the authors of the theory of practice architectures, of how the theory came about and has evolved. The theory was first articulated as the ‘theory of practice architectures’ by Stephen Kemmis and Peter Grootenboer in 2008 in the book Enabling Praxis: Challenges for Education. However, it was many years in the making before 2008, and it has continued to be refined since then through Kemmis and Grootenboer’s engagement in research and conversation with other scholars. The narrative presented here provides insights into many of the theory’s key influences, explaining how and why some of its central assertions and ideas have emerged. Thus the chapter builds on explanations of the theory presented in this book and elsewhere.
