Vygotsky’s Zone of Proximal Development (ZPD) describes the space where genuine learning happens: too easy, and there is nothing to learn; too hard, and the learner cannot progress. Calibrated support — scaffolding, in Bruner’s later coinage — lifts the learner across the gap, then is progressively withdrawn (fading).
The modern risk, with always-available AI, is what researchers now call the Zone of Non-Development: scaffolding that never fades. The learner appears to perform well, but only with the support. Independent capability never consolidates.
Fluera’s AI is designed to stay in the ZPD. Socratic prompts are calibrated against the current state of the canvas. Ghost Map reveals exactly as much as the gap requires. Nothing is volunteered that the learner could have generated independently.
