The Effect of Computer Based Feedback on Using Cognitive Strategies of Problem Solving
This study investigated the effects of solution-oriented and strategy-oriented feedback when using interactive computer-assisted instruction. The feedback confirmed problem solving strategies that were either similar to the learner's cognitive strategies (i.e., spatial strategies) or different from the learner's cognitive strategies (i.e., perceptual strategies). A pretest consisting of 32 three-term series problems was administered to the 65 undergraduates who served as subjects. They were then given four instructional guided discovery programs with identical instructions on the features of the problems and the relationships between the features. However, two of the programs gave instructions for spatial strategies to solve the problems, while the other two gave instructions for perceptual strategies to solve the problems. Posttests measured the effects of the instructional programs, and it was found that when the learners were instructed on the spatial strategies, strategy feedback was more effective than solution feedback. This suggests that feedback given throughout the instruction on problem solving modifies the learner's cognitive strategies only if the strategies in the instruction are similar--to some extent--to the learner's cognitive strategies. It was also found that strategy feedback was less effective in learning perceptual strategies than in learning spatial strategies, and less effective than solution feedback in learning the perceptual strategies. The text is supplemented by two figures and two tables. (28 references) (Author/EW)
