CORE DEFINITION

Concreteness fading is a theory of instruction that begins with a concrete instantiation of a concept and progressively moves toward more abstract representations while explicitly connecting corresponding relationships. Its original form typically uses three stages: physical enactment, an iconic depiction, and abstract symbols.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Help learners connect relationships in objects or images to abstract concepts and gradually reduce their reliance on concrete materials. The key is preserving conceptual structure and explaining correspondences; choosing an arbitrary physical metaphor and replacing it with terminology is insufficient.

The concreteness of a representation changes while its mathematical or conceptual relationships are explicitly retained. The aim is to help learners identify structure shared across representations and transfer it to new contexts. The cited paper presents testable hypotheses for a theory of instruction; it does not establish that every learner requires the same sequence or will necessarily transfer learning.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

To teach one half, have the learner divide a paper strip into two equal parts and select one. Draw the same whole and selected part, then connect them to the numerator and denominator in 1/2. Remove the strip, change the shape, and ask why the fraction is still one half. Return to the diagram if the correspondence is unclear.
