INTRODUCTION

English translation pending.

CORE DEFINITION

The concept combines Vygotsky's zone of proximal development with the scaffolding metaphor introduced by Wood, Bruner and Ross in 1976. Teachers or tools supply prompts, checklists and reflection sheets that stand in for the learner's immature self-monitoring, asking what the evidence is or whether the strategy is working, and these supports are then faded out as competence grows. The key constraint is direction: the support must target how to think about the task, not supply the answer itself.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Externalise the question: Use prompts like 'what is your evidence?' to turn silent monitoring into a visible check. - Fade the support: Hand planning to a checklist first, then remove items as competence grows. - Fix it afterwards: Debrief which strategy worked, so external prompts become an internal habit.

Anchor fast decisions

Self-monitoring consumes working memory, so novices cannot attend to the task and to their own thinking at the same time. An external prompt carries that monitoring load, freeing capacity for the task itself, and repeated use turns the prompt into an internal question the learner asks unprompted. Fading is what makes the support a scaffold rather than a crutch, since without withdrawal the learner keeps depending on the external cue.
