본 연구는 소수 나눗셈에서의 '몫'과 '나머지' 용어 사용의 문제점을 인식하고 이를 개선하기 위한 방안을 탐색하였다. 지금까지의 선행 연구와 현행 교과서를 분석한 결과, '몫', '나머지' 용어 사용에 대해 연구자마다 상이한 견해를 주장한 근원에 나눗셈 알고리즘에서의 q, r값과 계산 결과의 해석에 따른 결과 값과 남는 양을 동일하게 보는 데에 원인이 있음을 밝히고, 소수 나눗셈의 '몫'과 '나머지' 취급에 대한 일관된 관점과 교과서 개선 방안을 제안하였다. 즉, 나눗셈 알고리즘 b=a×q+r에 의한 소수 나눗셈의 결과인 q, r을 '몫', '나머지'로 보고, 문제 맥락에 따라 q와 같거나 작은 양을 최종적인 '결과 값'으로, 결과 값을 취하고 난 잔여량을 '남는 양'으로 지칭할 것을 제안하였다. 또한, 몫을 반올림하여 나타낸 근삿값을 '몫'으로 지칭하지 않을 것을 제안하였다.
In this study I recognized the problems with the use of the terms 'quotient' and 'reminder' in the division of decimal and explored ways to improve them. The prior studies and current textbooks critically analyzed because each researcher has different views on the use of the terms 'quotient' and 're...
