Teacher entries into second turn positions: IRFs in collaborative teaching

This article examines the underresearched classroom context of co-teaching. The study analyzes classroom interactions wherein two teachers-one American and one Korean-concurrently use English and Korean to carry out content-based lessons. Of analytic focus is the co-teacher's entry into the second turn position of initiation-response-feedback (IRF) sequences and the actions that the teacher deploys in these turns. The sequences exhibit a distinct interactional structure that departs from prototypical IRF sequences, revealing the participants' collaborative methods of managing classroom contingencies, organizing student participation, and accomplishing the curricular focus of the lesson.
