This study was completed to figure out if the implementation of project-based learning lessons had an impact on student behavior. Data was gathered from students that had behavior problems before and after implementing PBL lessons. Data was taken from the PBIS site that records major and minor referrals. Student surveys were also used to gather data about how students self-assessed their behaviors. This study found that there was a positive impact on student behavior. In the future, another study should be conducted where two curriculums are given to two separate groups.
