Piaget's Core idea.

Explanation:

Piaget’s stages are a theory of how a child’s cognition — meaning their knowledge and understanding about the world — develops between birth and adulthood.

Jean Piaget was an early psychologist who specialized in child development from the 1920s onward. Piaget developed his theories by watching children and making notes about their progress.

The core idea of Piaget’s theory is that children develop by acting as “little scientists” who explore and interact with their world to understand people, objects, and concepts. They do this naturally, even without the help of an adult.
