There are those who think about creating a “Piagetian curriculum” or “Piagetian teaching methods.” But to my mind these phrases and the activities they represent are contradictions in terms. I see Piaget as the theorist of learning without curriculum and the theorist of the kind of learning that happens without deliberate teaching. To turn him into the theorist of a new curriculum is to stand him on his head. – Seymour Papert, Mindstorms
