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. This appendix provides additional characteristics of the studies of "Good Behavior Game" that meet WWC single-case design standards, including 10 studies that contribute to the findings in the "Good Behavior Game" intervention report, and 15 studies that do not contribute to the findings because the What Works Clearinghouse (WWC) could not calculate a design-comparable effect size for any of the outcomes.
