The purpose of this action research study was to determine the impact of brief physical activity breaks on student engagement in the classroom, with a focus on off-task behaviors. Participants in the study were 21 seven to nine year olds who attended 3rd grade at an elementary school in Minnesota. Students completed a 3-5 minute GoNoodle guided movement video during the reading block over a 10 day intervention period. Data was collected by the researcher using a tally-mark chart to denote the frequency of off-task behaviors. The study concluded physical activity breaks had a positive effect on decreasing student off-task behaviors.
