The purpose of this dissertation is to reflect on and make sense of my practice as a teacher educator. As a response to the growing field of self-study research in the field of teacher education, my study answers the following question: What is my lived experience as a White teacher educator? This research took place during the student teaching semester of a teacher education program, and I attend to my research question through a framework of critical whiteness studies, with particular attention to the principles that approach whiteness as a racial perspective and as a racial identity. I then review the literature related to the history and development of teacher preparation, highlighting the significance of reflection as a learning tool within the context of the student teaching seminar. I also explore the nuanced relationship between teacher preparation and whiteness, including teacher education programs, teacher candidates, and teacher educators. I utilized a self-study of my teacher education practices as a methodology to examine my teacher education practices in the student teaching seminar, and I share my findings, which came from using thematic analysis to make sense of my data. I present my experience as a White teacher educator and the uncertainty of my identity as I explore myself as a teacher educator through the fractured roles of researcher, instructor, and colleague. I end this dissertation by highlighting the significance of my findings through a discussion of the impacts of whiteness on my work. Furthermore, I specifically address White teacher educators in sharing the three implications from this research for the larger fields of self-study research and teacher education: acknowledging and identifying the aggressive invisibility of whiteness; understanding and navigating the constant state of uncertainty that White teacher educators find themselves in; and the need for dedicated and protected time for White teacher educators to reflect on their identity and practice.
