Concrete Fade-Out

INTRODUCTION
English translation pending.
CORE DEFINITION
Concrete fade-out extends Bruner's CPA model by prescribing a sequence for teaching abstraction: enactive representation through physical objects, then iconic representation through images, then symbolic representation through notation. The core proposition is that the concrete supports should be withdrawn gradually as understanding deepens, not eliminated at the start. The key qualification is that a learner who cannot follow signals that the support was removed too early, so the correct response is to step back one level and rebuild before climbing again.
SCAFFOLDING EFFECT
Reduce cognitive load
- Cognitive ladder: Move learners through objects, then images, then symbols instead of starting with formulas. - Early-fade warning: Treat a confused learner as evidence that the concrete support was withdrawn too soon. - Step-back move: Return one level down when a learner stalls, then climb again with the support restored.
Anchor fast decisions
Representation proceeds from action to image to symbol, and each stage makes the next one intelligible. As understanding deepens the concrete supports are withdrawn so cognition can settle at the abstract level, but a learner who stalls reveals that the withdrawal came too early, and the sequence must back up one rung before it continues.
