Description

The article defines a knowledge component as 'an acquired unit of cognitive function or structure that can be inferred from performance on a set of related tasks' and classifies KCs along four dimensions: whether task features and response are constant or variable, whether the feature-response relationship is implicit or explicit, and whether a rationale is known. This yields categories such as facts (constant-constant, explicit), categories and concepts (variable-constant), productions, skills, rules and plans (variable-variable), and principles with rationales. KCs are chosen at the level where novice students actually make errors.
