Zone of Proximal Development (Vygotsky)

Lev Vygotsky's concept describing the gap between what a learner can do independently and what they can do with guidance. Learning happens most effectively within this zone—tasks too easy produce boredom, tasks too hard produce frustration, but tasks just beyond current ability with appropriate support produce optimal growth. The ZPD is dynamic: as skills develop, the zone shifts, requiring continuously calibrated challenge.
