ABSTRACT: The role of early childhood education in developing self-regulation skills is crucial for fostering children's ability to manage their emotions, behavior, and attention. This study investigates how early childhood education programs contribute to the development of self-regulation skills. The objectives are to (1) assess improvements in children's self-regulation skills, (2) evaluate the integration of self-regulation activities in early childhood education curricula, and (3) examine changes in classroom behavior and learning outcomes. A survey design is justified as it enables comprehensive data collection on educational impacts on self-regulation. A purposive sample of 120 children from various preschools in Lagos State was used to ensure relevant experiences. The case study focuses on a preschool known for its emphasis on self-regulation activities. Findings indicated significant improvements in children's self-regulation skills, the effectiveness of self-regulation activities in the curriculum, and positive changes in classroom behavior and learning outcomes. Recommendations included incorporating structured self-regulation activities into early childhood curricula and training teachers on effective self-regulation strategies to support children's development.
