The document discusses Piaget's theories of cognitive development and their educational implications. Piaget believed that children actively construct mental models of the world through experience. This contrasted with behaviorist views that children are passive vessels to be molded. By the 1960s, Piaget's ideas influenced the development of new education systems by emphasizing understanding over rote learning and accommodating individual developmental differences. His work established principles like focusing on thinking processes over products and encouraging self-initiated, active learning through hands-on experience.
