Résumé
The representation of physics problems in relation to the organization of physics
knowledge is investigated in experts and novices. Four experiments examine {a~
the existence of problem categories as a basis for representation; (b) differences
in the categories used by experts and novices; (c) differences in the knowledge
associated with the categories; and (d) features in the problems that contribute to
problem categorization and representation. Results from sorting tasks and protocols
reveal that experts and novices begin their problem representations with
specifiably different problem categories, and completion of the representations
depends on the knowledge associated with the categories. For, the experts
initially abstract physics principles to approach and solve a problem representation,
whereas novices base their representation and approaches on the problem's
literal features.
