Abstract

This study examined the relationship between preservice teachers' mathematical understanding and problem posing in fractions multiplication and division. To this purpose, 41 preservice teachers performed visual representation and problem posing tasks for fraction multiplication and division, measured their mathematical understanding and problem posing ability, and examined the relationship between mathematical understanding and problem posing ability using cross-tabulation analysis. As a result, most of the preservice teachers showed conceptual understanding of fraction multiplication and division, and five types of difficulties appeared. In problem posing, most of the preservice teachers failed to pose a math problem that could be solved, and four types of difficulties appeared. As a result of cross-tabulation analysis, the degree of mathematical understanding was related to the ability to pose problems. Based on these results, implications for preservice teachers' mathematical understanding and problem posing were suggested.

본 연구는 분수의 곱셈과 나눗셈에서 예비교사의 수학적 이해와 문제 만들기 사이의 관련성을 탐색하였다. 이를 위해여 41명의 예비교사들을 대상으로 분수의 곱셈과 나눗셈에 대한 시각적 표현과 문제 만들기 과제를 수행하고 수학적 이해 정도와 문제 만들기 능력을 측정하였으며, 수학적 이해 정도와 문제 만들기 능력 사이의 관련성을 교차분석을 통해 알아보았다. 그 결과, 예비교사들의 대부분은 분수의 곱셈과 나눗셈의 개념적 이해를 나타냈으며, 다섯 가지 유형의 어려움이 나타났다. 문제 만들기에서는 대부분의 예비교사들이 풀 수 있는 수학 문제를 만들지 못했으며 이 과정에서 네 가지 유형의 어려움이 나타났다. 또한 교차분석 결과, 수학적 이해 정도는 문제 만들기 능력과 연관이 있었다. 이러한 결과를 바탕으로 예비교사의 수학적 이해와 문제 만들기에 대한 시사점을 제시하였다.
