CORE DEFINITION

This model, grounded in Vygotsky's zone of proximal development, provides temporary support such as hints, templates, worked examples, or decomposed steps for work just beyond the learner's current ability, and removes that support as competence grows. Its core proposition is that capability expands fastest when assistance fills exactly the gap between what the learner can do alone and what they can do with help. The key qualifier is withdrawal: support that is never removed becomes dependence, and support removed too early produces failure.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Gap sizing: match the support to the specific step the learner cannot yet do alone. - Support selection: choose hints, templates, or worked examples rather than doing the task for them. - Fading schedule: remove the support step by step as the learner's performance clearly stabilizes.

Anchor fast decisions

Work beyond current ability fails without help, and work well within it produces no growth, so the productive zone is narrow. Support placed exactly at the gap lets the learner complete the task and encode the successful procedure. Fading the support then forces the learner to perform the same procedure independently, which is what converts assisted success into owned skill.
