Abstract
The purpose of this study is to analyze and diagnose the type of errors indicated by the students in the process of calculation of the fractional multiplication and division, and to propose teaching methods, to effectively correct errors. The results obtained through this study are as follows. First, based on the results of the preliminary examination, 6 types of errors of the fractional multiplication and division has been organized. In particular, the most frequent types of errors are algorithm errors. Therefore, a teacher should explain the meaning and concept of fractional multiplication and division. Second, 4 prescription methods are proposed for understanding fractional multiplication and division. Third, according to the results of this study, it was effective to diagnose underachievers' error types and give corrective lesson according to the cause of the error types. Throughout the study, it's concluded that it is necessary to analyze and diagnose the error types of fractional multiplication and division, and then a teacher can correct error types by 4 proposed prescription methods. Also, 5 students showed interest while learning, and participated actively.
본 연구는 분수의 곱셈과 나눗셈 계산 과정에서 학생들이 보이는 오류 유형을 분석하고 진단하여, 오류를 효과적으로 교정하기 위한 오류 유형별 지도방안을 구안하는 데 그 목적이 있다. 이를 위하여 초등학교 6학년 2개의 학급을 대상으로 분수의 곱셈과 나눗셈에서 보이는 주요 오류 유형을 6가지로 분류하고 연구 대상의 오류 유형을 진단하였으며, 각 오류 유형에 맞는 교정 지도방안을 구안하여 적용하였다. 오류가 교정되었는지를 판단하기 위하여 사후평가를 2회 실시한 결과 연구 대상의 오류가 교정된 것으로 나타났다.
