Abstract

This study was conducted for one semester through one group pretest-posttest design with 49 first-year middle school students to explore the effects of mathematics-centered STEAM class experiences on students' mathematical modeling abilities. The main results of this study are as follows: First, the results of the pre and post-mathematical modeling ability tests showed that the average score of posttest was improved compared to the pretest, and that the experiences of mathematics-centered STEAM classes provided in this study had a positive effect on improving the mathematical modeling ability of first-year middle school students. Second, STEAM classes were more effective in solving mathematical modeling problems that require students' creative and divergent thinking. Third, the content analysis of student responses for each subquestion showed that STEAM classes were especially more helpful in activating students' mathematical model construction and validating steps.

본 연구는 수학교과 중심의 STEAM 수업 경험이 중학교 1학년 학생들의 수학적 모델링 능력에 미치는 영향을 파악하기 위하여 대학 연계 자유학기제 융합수학탐구 수업에 신청한 49명의 학생들을 대상으로 단일집단 사전-사후 검사 설계를 통해 한 학기동안 이루어졌다. 본 연구의 주요 결과는 다음과 같다. 첫째, 사전, 사후 수학적 모델링 능력 검사 결과에 의하면, 사전 검사에 비해서 사후 수학적 모델링 검사의 평균 점수가 향상되었고, 사전, 사후 검사 간에 통계적으로 유의미한 차이가 있는 것으로 나타나 본 연구에서 제공한 수학교과 중심의 STEAM 수업 경험이 중학교 1학년 학생들의 수학적 모델링 능력을 향상시키는데 긍정적인 영향을 준다는 것을 확인하였다. 둘째, 각 문항별 분석 결과에 의하면 STEAM 수업 경험은 학생들의 창의적 사고 및 열린 사고를 요구하는 개방성이 높은 수학적 모델링 문항의 해결에 더욱 효과적인 것으로 나타났다. 셋째, 하위문항별 학생 응답 내용 분석 결과에 의하면, STEAM 수업 경험이 특히 학생들의 수학적 모델 구성 및 결과에 대한 타당성 검토 과정을 더욱 활성화시킨 것으로 나타났다.
