When adult ESL (English as a Second Language) learners enter our classrooms with little or no first language literacy, their instructors teach them to read for the first time in an unfamiliar language. It is a tremendous task, and the context for teaching "adult emergent readers" is complex. This complexity is coupled with a growing, but still limited, research base to draw from and few professional development opportunities to guide instruction. Workshops rarely move beyond simply learning new activities and locating resources. As for all teachers, professional growth happens best in sustained, collective, focused professional learning that allows for deep reflection on practice, ties to research, and extensive interaction with colleagues. Study circles are a possible solution to this pressing professional development need. The current study outlines a study circle specifically designed for teachers of adult ESL emergent readers and explores how it was experienced by participants in a pilot study. The element of interaction is central to this inquiry, and the author outlines the nature and value of the interaction the teachers experienced. (Contains 3 tables.)
