The High/Scope curriculum is an early childhood education model based on Jean Piaget's constructivist theory that children learn best through hands-on experiences. The curriculum focuses on active learning in small groups and follows a "plan-do-review" sequence. It emphasizes allowing children to guide their own learning activities within a consistent daily routine, while educators observe and provide a stimulating environment. The High/Scope approach has been successfully implemented with children from infancy through early elementary school.
