The Capturing Kids' Hearts program aims to develop healthy relationships within schools through relationship-building techniques and teaching social and emotional skills. It utilizes the EXCEL model which consists of 5 steps - Engage, Xplore, Communicate, Empower, Launch. These steps guide teachers in developing rapport with students, understanding student needs, effectively delivering content, empowering student learning, and concluding lessons. Additional tools taught include the Social Contract for establishing classroom expectations and the Four Questions for addressing misbehavior and disrespect.
