Negative Instances and the Acquisition of the Mathematical Concepts of Commutativity and Associativity. Final Report.
Shumway, Richard J.
The role of negative instances in the acquisition of the mathematical concepts of commutativity and associativity of a binary operation was examined. Two levels of instruction (positive instances, and positive and negative instances) for commutativity and for associativity were crossed to form a 2 x 2 factorial design with 16 ninth grade subjects per cell. Criterion variables were number of correct responses, stimulus interval, and postfeedback interval during treatments and/or posttests. The results appeared to favor the treatments containing both positive and negative instances and supported the hypotheses that the effect of negative instances transferred from one concept to another.
