| Abstract | This research study focused on the knowledge structure of the domain of physics by describing the knowledge of experts, intermediates, and novices. In order to investigate these representations, a reiterative categorization task was employed using novice, intermediate, and expert subjects (N=27). The categories were classified as theory-, model-, or mathematical model-based categories, and proportions of these categories were compared by level of expertise in order to compare subjects' categorization with the competing models. Results support a combined representation of physics knowledge based on both theories and models with the novice representation being a hierarchy of models. The highest level for both intermediates and experts was the theory used to solve the problem. Model-based categories were used by experts at the lowest level of categorization. (Contains 37 references, 10 tables, and 4 figures.) (DDR) |
