아동의 수 직선 추정의 정확도와 수학 성취도 간의 관계에 대한 숫자 비교 능력의 매개 효과

초록

Many studies are being conducted to understand factors that influence mathematical problem solving ability and the mechanism through which it develops. The present study conducted mediation analysis to examine which basic numerical cognitive abilities contribute to math achievement and whether there is a mediating factor in this relationship. The present study measured the precision of number estimation, number processing ability, numerosity comparison ability as basic numerical cognitive abilities. As a result of the mediation analysis, we found that number comparison efficiency mediates the relationship between the precision of the internal number representation (measured with number estimation) and math achievement. This finding suggests the possibility that a stepwise intervention of first improving the precision of the internal number representation and then training to efficiently process symbolic numbers will contribute to the enhancement of math achievement in children with mathematical disabilities.
