The purpose of this action research project was to determine the difference in behavior and engagement by comparing two teaching styles. Participants were 10 five-year-olds in a public, inclusive, half-day transitional kindergarten setting. Data was collected through observation during 30-minute lessons for a five-week period. Specific behaviors were tallied, as well as teacher observation of student engagement and recording of standards completed during each lesson. Analysis of the data collected suggests that play-based teaching has positive impacts on decreasing behaviors and increasing student engagement.
