Learning together as teachers and researchers: Growing shared expertise in a self-study community of inquiry.

The authors of this study are 14 Dutch teacher educators who worked together as a self-study community of inquiry (COI) over one year. The aim of the group was to learn about, and facilitate, self-study research by participants in a planned and systematic way, within a supportive network. The project design was informed by a set of guidelines for supporting a self-study COI that had been articulated, refined and revised over several years. In this study, we revisit the guidelines, and in particular two recently added guidelines, as we sought to interpret and enact them within our COI.
