CONCEPT
Objects to Think With
Papert’s term for any artifact—physical or digital—that embodies a principle, responds to manipulation, and enables the learner to discover that principle through the act of handling rather than through instruction.
The concept originates in
Seymour Papert’s childhood relationship with the gears of a toy differential. He did not study those gears or learn about them; he played with them until their behavior was intimate, turning them in his hands until the abstract relationships of ratio, proportion, and mechanical advantage had been deposited into his body as understanding rather than his memory as information. He generalized this experience into the concept of objects to think with: artifacts whose behavior embeds mathematical or scientific principles in a form the learner can encounter through manipulation. The turtle was the canonical object to think with for geometry—directing it to draw a circle required the learner to construct, procedurally and precisely, what a circle actually is. LEGO Mindstorms robots were objects to think with for mechanics and feedback. What made an artifact qualify was a specific combination of properties: it had to be manipulable, so the learner could act on it; responsive, so the consequences of that action
