This study explores the role that teacher educators themselves may play in instances of limited success. The first author used self-study to explore how his framing of his facilitation role created a defensive rather than an open-to-learning professional development experience. This article has described how, despite being skilled in teaching, the first author was not skilled in helping teachers learn, at least initially. By building on the work of Argyris and Scho¨n (1974), this article describes a self-study process that involves using transcripts to infer the beliefs and values that underpin in-service educators’ decisions about how to act.
