Papert's constructionism inverts instructionism: 'the child programs the computer,' not the reverse

Seymour Papert extended Jean Piaget's constructivism — knowledge is built, not transmitted — into what he named constructionism: knowledge is built most effectively while the learner is building something real and shareable in the world. The claim is grounded in his years training under Piaget in Geneva (claim-papert-coauthored-perceptrons-after-piaget-training) and stated most sharply in Mindstorms: Children, Computers, and Powerful Ideas (1980), where Papert set constructionism against instructionism — the model in which the machine (or teacher) programs the learner. His inversion: "In my vision, the child programs the computer." The computer becomes an object to think and build with, not a tutor that dispenses lessons. This thesis is the conceptual root of Logo, the programming language for children he developed at MIT in the late 1960s.

The [unverified-quote] flag stands because the exact wording and page are taken from Papert's own site (papert.org, Tier 1 carrier) rather than a direct read of the 1980 book; verification is routed at question-verify-papert-mindstorms-child-programs-computer-quote.
