Q: The effects of variety upon the learning of the mathematical concepts of Boolean set union and intersection were studied. Ss from 5th and 7th grades were selected from four randomly selected schools. They were randomly assigned to four fixed experimental conditions which varied in two ways. Ss in the large variety conditions were given 48 different problems to solve. Subjects in the small variety conditions were given eight problems to solve with each problem repeated six times. The stimuli employed with one-half on the Ss were familiar geometric forms for which a verbal label was readily available. Stimuli for the remaining Ss were unfamiliar random forms they had never seen before.
