Size Comparison Ability and Strategies of Young Children

3, 4, 5세 유아의 크기비교 능력 및 전략

In this study of age differences in the correct judgment of relative size and size comparison strategies, 114 three-, four-, and five-year-old children were asked to judge the relative size of 2 figures. Findings were that older children judged size comparison more correctly than younger children. The 5-year-old children used the strategy of superimposition more frequently than younger children, though children in all age groups most frequently used the strategy of one sided comparison with one side of each figure touching the other. The strategy in which one figure is put on top another with a general shape adjustment led most frequently to correct judgment of the relative size of 2 figures.
