Findings from an Experimental Evaluation of Playworks: Effects on Play, Physical Activity and Recess

Accelerometer data showed that Playworks had a positive impact on students’ physical activity during recess. Students in treatment schools engaged in physical activity during recess that was, on average, more intense than the physical activity engaged in by control students. Moreover, students in treatment schools spent significantly more time engaged in vigorous physical activity at recess than students in control schools. Teachers in treatment schools reported better recess behavior and readiness for class than teachers in control schools.
