Teachers can use a variety of classroom management practices to help foster a classroom environment in which all students can learn. "Good Behavior Game" is a specific classroom management strategy that aims to improve social skills, minimize disruptive behaviors, and create a positive learning environment. Teachers place students into teams and reward them for demonstrating appropriate behaviors and following classroom rules. The What Works Clearinghouse (WWC) reviews existing research on educational interventions to identify evidence-based programs and practices. This WWC intervention report summarizes the available evidence on the effects of "Good Behavior Game" on student and teacher outcomes. [For the Intervention Brief, see ED628138.
