This article explores how mapping patterns of student participation in classroom discussion can both illuminate and complicate the dynamic relationships among identity, physical position in the classroom, student engagement, and course content. It draws on the perspectives of an undergraduate in the role of pedagogical consultant, a faculty member who worked in partnership with that student, and the coordinator of the program through which this collaborative exploration unfolded. The authors provide multiple angles of vision on the impetus behind, approach to, results of, and interdisciplinary possibilities of mapping classrooms and offer recommendations and cautions regarding the use of mapping.
