Answer:
Jean Piaget's theory of human development, known as Piaget's theory of cognitive development, focuses on how children construct knowledge and understand the world around them. Piaget proposed that children progress through four stages of cognitive development: the sensorimotor stage, the preoperational stage, the concrete operational stage, and the formal operational stage.
In each stage, children develop new ways of thinking and understanding based on their experiences and interactions with the environment. Piaget emphasized the importance of play and exploration in children's learning processes. His theory has had a significant impact on education and child psychology, highlighting the active role of children in their own development.
