Cognitive Theory of Development by Jean Piaget
Jean Piaget is a name that echoes through every classroom, psychology textbook, and parenting guide, yet the depth of his work is often reduced to a simple list of four stages. His cognitive theory of development by Jean Piaget fundamentally changed how we understand the mind of a child, proposing that children are not merely passive recipients of knowledge but active builders of their own understanding. This theory suggests that intelligence is not a fixed trait present at birth, but a dynamic process that evolves as we interact with the world.
