본 연구에서는 분수 학습을 마친 초등학교 6학년 학생 150명을 대상으로 분수의 5가지 의미에 관한 20개의 문항을 제시하였고, 학생들의 반응을 단위의 이해에 초점을 두어 분석하였다. 연구 결과, 전체-부분으로서의 분수에 익숙한 학생들은 분수의 다른 의미에서도 주어진 전체를 단위로 인식하는 오류를 많이 보였다. 또한, 각 의미별로 단위와 관련된 다양한 반응들이 나타났다. 이러한 연구 결과를 바탕으로 각각의 분수의 의미를 지도할 때 단위와 관련된 강조사항을 확인하여 시사점을 제공하고자 한다.

The purpose of the study was to investigate the influence of children's understanding of fractions in mathematics problem solving. Kieren has claimed that the concept of fractions is not a single construct, but consists of several interrelated subconstructs(i.e., part-whole, ratio, operator, quotient and measure). Later on, in the early 1980s, Behr et al. built on Kieren's conceptualization and suggested a theoretical model linking the five subconstructs of fractions to the operations of fractions, fraction equivalence and problem solving. In the present study we utilized this theoretical model as a reference to investigate children's understanding of fractions. The case study has been conducted with 6 children consisted of 4th to 5th graders to detect how they understand factions, and how their understanding influence problem solving of subconstructs, operations of fractions and equivalence. Children's understanding of fractions was categorized into "part-whole", "ratio", "operator", "quotient", "measure" and "result of operations". Most children solved the problems based on their conceptual structure of fractions. However, we could not find the particular relationships between children's understanding of fractions and fraction operations or fraction equivalence, while children's understanding of fractions significantly influences their solutions to the problems of five subconstructs of fractions. We suggested that the focus of teaching should be on the concept of fractions and the meaning of each operations of fractions rather than computational algorithm of fractions.
