In this article we describe a self-study research project. As one professor and six doctoral students, we co-taught a course on action research while doing a self-study of our teaching. We studied ourselves, and our students, as we taught this course. We report on what we learned from this co-teaching and co-researching. We analyze how we worked together, how we conducted the research, and the process used to integrate our individual and collective reflections into a collaborative text. There were common themes in our learning but at times we speak in individual voices because our experiences were not all the same. The co-teaching, the collaborative analysis of our data, and writing about our research were separate aspects of our self-study yet each of these fed our relationships, our thinking about teacher education and action research within it, and our future, and present, lives as university professors in teacher education.
