This book introduces a research method called 'auto-teach(er)/ing-focused research, ' a research process that aims to document understandings generated by, and for the teacher when that teacher teaches or re-teaches a course. It demonstrates how this method is applied by the author/researcher within the pedagogical space that is the teaching of a course, one that has been taught numerous times by the author/researcher over many years. This book documents understandings about learning and teaching that have emerged within the pedagogical space that is the teaching of a course, and the pedagogical space that is the writing of a book. It explores the notion that pedagogical spaces are complex, and that subjects navigate and are produced within them in a multiplicity of ways. This book applies a research method that generates a knowledge product that research practitioners in a variety of settings might find useful to adopt or adapt.
