Social and emotional learning (SEL) is an approach that teaches self-regulation, self-monitoring, and social skills in school settings. SEL has been shown to be an effective method of reducing negative social interactions and increasing academic achievement. This article relates the experiences of one intermediate school principal and her staff as they used SEL strategies to change the climate and culture of their highly diverse school population. Classroom management is discussed as the vehicle used by the teachers, while the principal aligned school procedures with the philosophy of SEL. The article describes the lessons they learned and suggests directions for future research into how SEL can make effective and meaningful contributions to the field of education.
