A Study of Knowledge Structure in Physics.
Discenna, Jennifer
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)
