In this self-study, the author investigates the gap between best and actual practices, as experienced by a university teacher educator who spent a year as a student teacher in a middle and high school English language arts program. Occupying the identities of a student, a student teacher, a teacher educator, and a researcher, she explored the gap from these multiple perspectives, with the intent of learning how to better support student teachers' development. Her findings fall into three distinct phases: (1) In “Mind the gap,” she explains the dilemma she encountered as a student teacher. (2) In “Mine the gap,” she describes the process of exploring the nature and extent of this dilemma. (3) In “The gap is mine,” she analyzes a shift in her understanding of where the gap is located.
