The purpose of this action research study was to determine the effectiveness of brain breaks on behavioral engagement in middle school computer science classrooms. The two questions that drove this action research study were: should brain breaks be used in a middle school computer science classroom and do brain breaks help middle school computer science students stay engaged. This action research study was conducted in two middle school computer science classrooms in a Northeast Iowa school. Quantitative data was collected on behavioral engagement in both classes for 15 days which indicated the percentage of students behaviorally engaged and disengaged at three-time intervals each day. A qualitative analysis was completed with Google Form survey data that was given to the participants in each of the two classes.
