The parent training intervention focuses on strengthening parenting competencies and fostering parents' involvement in children's school experiences to promote children's academic and social skills and reduce delinquent behaviors. The Dinosaur child training curriculum aims to strengthen children's social and emotional competencies, such as understanding and communicating feelings, using effective problem-solving strategies, managing anger, practicing friendship and conventional skills, and behaving appropriately in the classroom. The teacher training intervention focuses on strengthening teachers' classroom management strategies, promoting children's prosocial behavior and school readiness, and reducing children's classroom aggression and noncooperation with peers and teachers. The intervention also helps teachers work with parents to support their school involvement and promote consistency between home and school. In all three training interventions, trained facilitators use videotaped scenes to structure the content and stimulate group discussions and problem solving.
