6~8세 아동의 수감각 수준 비교

다국어 초록 (Multilingual Abstract)

The purpose of this study is to compare the number sense level of children in terms of age (6, 7, 8 years) and group (normal vs lower 25%). For this purpose, 237 children in two kindergartens and two elementary schools in A area were tested for the number sense. The number sense test tools consist of 11 factors, 143 items including number recognition, counting, skip counting, quantity discrimination, number meaning, missing number, number transformation, addition/subtraction, pattern, estimation, and measure. The results from this study are as follows. First, as a result of analyzing the main effects of age on the total score of the number senses, there was a difference in the total of the number senses according to age. As a result of analyzing the main effects of group on the total of the number senses, there was a difference in the total score of number senses according to groups. As a result of analyzing the interaction effect between age and group, the interaction effect was significant in the total score of the number sense. Second, as a result of analyzing the differences in the number sense scores by age, there were significant differences in the total score and scores of all factors. Third, as a result of analyzing the differences in the number sense scores by group, there were significant differences in the total score and scores of all factors. Fourth, as a result of analyzing the differences in the number sense scores by age of the normal group, there were significant differences in the total score and scores of all factors. As a result of the post-hoc test to determine the differences among ages, the 7- and the 8-year-old groups were higher than the 6-year-old group in the quantity discrimination and missing number, and there were no differences among the ages in the measure. As a result of analyzing the differences in the number sense scores by age of the lower 25% group, there were significant differences in the total score and scores of all factors. As a result of the post-hoc test to determine the differences among the ages, the 8-year-old group showed a higher score than the 6- and the 7-year-old group in skip counting, the 7- and 8-year-old group showed higher scores than the 6-year-old group in the number recognition, quantity discrimination, pattern, measure, and estimation. These results show that both the normal group and the lower 25% group increase the number sense ability according to the increase of age, but the difference is in the number sense score by the factors. In particular, the lower 25% group tends to be stagnant in the development of the number sense in several factors, suggesting that early intervention is required for the low-level group.
