The document summarizes three approaches to improving school discipline practices: ecological approaches to classroom management, schoolwide positive behavioral supports (SWPBS), and social and emotional learning (SEL). Ecological approaches focus on improving the quality and engagement of classroom activities. SWPBS establishes schoolwide systems to teach and reward positive behaviors while intervening with at-risk students. SEL builds students' social-emotional skills and sense of connection to improve self-discipline. While different, the approaches can be combined to create environments that promote learning, development, and order.
