A teacher is doing something right when his high school students--kids with limited English, no less--form groups and begin discussing a lesson on quadratic equations at the start of class, without any teacher direction. Bondie, Gaughran, and Zusho describe "discussion routines" that teachers at International Community High School in the South Bronx use to foster this kind of student engagement and eagerness to learn from one another. The routines enable students to take charge of their own learning and assist one another--and especially help English language learners gain confidence in conversing about academic content. The authors describe in detail two such routines--Elbow Partner Exchanges and Homework Rounds--and share tips and examples to help teachers in any subject area use these routines to foster powerful student discussions.
