Jean Piaget

"Schemas become increasingly complex and sophisticated through development."

"The adolescent can now reason about abstract hypothetical situations."

"Play provides the optimal conditions for cognitive and social development."

"The child who is encouraged to think critically will become an independent thinker."

"Sensorimotor experience is the foundation for all later cognitive development."

"The mind grows through conflict and resolution with the environment."

"Educational reform must be based on scientific understanding of child development."

"The child's sense of self develops through interaction with others."

"Imitation is the bridge between the child's actions and symbolic thought."

"The capacity for wonder is more important than the accumulation of facts."

"Children are not preparing for life; they are living life now."

"The structure of the mind is determined by how it has adapted to reality."

"Questions are more valuable than answers because they guide further inquiry."

"The child constructs a model of the world through playful experimentation."

"True cooperation requires mutual respect and shared goals."

"The development of moral reasoning is a gradual process of internalization."

"Children should be encouraged to ask questions and to question their questions."

"The mind is not a mirror of reality but an active constructor of understanding."

"Disequilibrium drives the process of adaptation and learning."

"The child's play is not frivolous; it is the serious business of development."

"Education should aim at producing citizens capable of independent thought."

"Language develops in the context of meaningful social interaction."

"The child learns best when intrinsically motivated by curiosity and interest."

"Socialization and cognitive development are intertwined processes."

"The educator should be a student of children, not merely a transmitter of information."
