Conceptual Entities

Abstract

The concept of the ontology of a problem domain is proposed and discussed. An ontology distinguishes the terms in a representation that refer to entities, from those that refer to attributes and relations. Entities are cognitive objects that a problem solver can reason about directly, and that are included continuously in the representation. Entities are hypothesized to (1) facilitate formation of analogies between domains, (2) enable use of general reasoning methods, (3) enhance computational efficiency, and (4) facilitate planning. Examples from analyses of problem solving and instruction that illustrate and clarify these functions are discussed.
