Abstract

The purpose of this study is to investigate the effects of classes using AlgeoMath on fifth grade elementary students' mathematical problem-solving skills and mathematical attitudes. For this purpose, the 'cuboid' section of the 5th grade elementary textbook based on AlgeoMath was reorganized. A total of 8 experimental classes were conducted using this teaching and learning material. And the quantitative data collected before and after the experimental lesson were statistically analyzed. In addition, by presenting instances of experimental lessons using AlgeoMath, we investigated the effectiveness and reality of classes using engineering in terms of mathematical problem-solving ability and attitude. The results of this study are as follows. First, in the mathematical problem-solving ability test, there was a significant difference between the experimental group and the comparison group at the significance level. In other words, lessons using AlgeoMath were found to be effective in increasing mathematical problem-solving skills. Second, in the mathematical attitude test, there was no significant difference between the experimental group and the comparison group at the significance level. However, the average score of the experimental group was found to be higher than that of the comparison group for all sub-elements of mathematical attitude.

본 연구의 목적은 초등학교 5학년을 대상으로 알지오매스를 활용한 수업이 학생들의 수학적 문제해결력 및 수학적 태도에 미치는 효과를 알아보는 데 있다. 이를 위해서 초등학교 5학년 수학 교과서의 '직육면체'를 재구성한 알지오매스 기반 교수·학습자료를 사용해서 총 8차시의 실험 수업을 실시하였다. 그리고 실험 수업의 전후에 수집한 양적 자료들을 통계적으로 분석하였고, 또한 알지오매스를 활용한 실험 수업의 장면을 구체적으로 제시함으로써, 수학적 문제해결력과 태도의 측면에서 공학을 활용한 수업의 효과와 실제를 알아보았다. 본 연구의 결과는 다음과 같다. 첫째, 수학적 문제해결력검사에서 실험집단과 비교집단은 유의수준 0.05에서 유의미한 차이가 있었다. 즉, 알지오매스를 활용한 수업은 수학적 문제해결력의 신장에 효과가 있는 것으로 나타났다. 둘째, 수학적 태도 검사에서 실험집단과 비교집단은 유의수준 0.05에서 유의미한 차이가 없었지만, 수학적 태도의 모든 하위 요소들에 대해서 실험집단이 비교집단보다 평균 점수가 상승한 것으로 나타났다.
