Knowledge Representation in Novice Physics Problem Solvers.
Pallrand, George J.
This investigation focuses upon the question of: (1) how naive subjects organize and represent knowledge when solving problems; (2) how previous experience of a novice is used in solving a problem; (3) what kinds of information and knowledge are sought as well as overlooked by novices when solving problems; (4) what kinds of strategies novices employ when solving problems; and (5) what cognitive abilities can be associated with the more successful novice problem solver. The problems selected were based upon a phenomenon about which every individual has some general awareness and common understanding. The problem series presented a sequence of phases, each of which builds upon the previous one. The sequence required the subject to restructure the problem elements previously used in a new and extended environment. Problem sequences were presented to individual subjects via a clinical interview. Once the subject had presented his or her view of the problem phase, it was graphically simulated on the computer screen. The subject then compared his or her interpretations of events with that generated by the computer. This study involved 10 graduate students in a master's level program for elementary education. In general the subjects that made the greatest progress were those that were able to construct, adjust and redefine problem representations. (CW)
