    Problem solving in physics: an information processing approach to the solution of kinematics problems
    Blackburne, Graham L. ( 1987)
    Many high school students experience difficulty in solving problems in physics that require only elementary mathematical skills. This study describes the evaluation of a computer aided instruction (CAI) package developed to instruct students to solve numerical problems in introductory kinematics. This package (Blackburne, 1986) was based on an information processing strategy using five equations of motion which allow the use of one routine to solve any of these problems. The evaluation was carried out in the context of a Year 10 science course. Three methods were investigated. Two of these methods were based on the information processing strategy. One of these was the CAI method, and the other, a classroom adaption of the computer method. The third method was a traditional classroom approach as outlined in most common physics texts that use three equations of motion. Results showed that the method made the difference, not the medium of the computer. Both the information processing methods yielded significantly fewer errors than the traditional method. An analysis of the kinds of errors made revealed that the most significant difference occurred in the selection of the correct rule to solve the problem then, to a lesser extent, the correct interpretation of the question and extraction of the relevant data.
