INTRODUCTION

CORE DEFINITION

The Frayer Model is a graphic organizer for concept learning developed by Dorothy Frayer and colleagues. A target concept sits in the center, surrounded by four quadrants: a definition, key characteristics or attributes, examples that belong to the concept, and non-examples that do not. The design rests on the claim that concept boundaries are learned through contrast as much as through description, so a definition alone leaves learners unable to decide whether a borderline case qualifies. Non-examples are the distinctive element, since they force the learner to specify what the concept excludes.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use non-example forcing: for every example, name a near miss that does not qualify and say why. - Use attribute listing: write the characteristics that must be present for membership. - Use boundary testing: apply your attributes to a borderline case to see whether the definition holds.

Anchor fast decisions

Concepts are categories, and categorizing requires a rule for membership rather than only a description. Definitions state the rule abstractly, but learners often over-generalize or under-generalize because they never test the boundary. Adding non-examples makes the boundary explicit by contrast, which forces the learner to identify the discriminating attribute rather than a superficial similarity. Because the four quadrants must stay consistent with one another, filling them in also surfaces contradictions in the learner's understanding, which is where revision happens.
