Ideally, the learning dynamic between teachers and their students is a reciprocal one, wherein students learn from teachers and teachers learn from students. Though teachers can learn from all students, a particular group--second language learners--may open even wider spheres of learning. In this article, the authors explore this notion of teachers learning from second language learners. The article begins with a description of second language learners and the unique challenges that these students and their teachers encounter in today's classrooms. Next, drawing from an informal questionnaire sent to teachers who work with second language learners, the authors identify and discuss three themes related to the expansion and enhancement of teacher learning. Interwoven throughout the discussion of the three themes are excerpts from stories of teachers who work with second language learners in a variety of educational settings.
