인지적으로 안내된 교수(CGI)의 원리를 적용한 수학 수업 연구

A Study on Mathematics Teaching Based on CGI in Elementary Schools

본 연구는 CGI의 원리를 우리나라 초등학교 교실 수학 수업에 적용해 보고, 학습자의 사고와 행동 특성, 교사가 느끼는 긍정적인 점과 어려운 점을 분석하였다. 연구를 위해 3학년 한 학급 학생들을 대상으로 수업을 한 결과, 첫째, CGI의 원리를 적용한 수학 수업은 학생들에게 자신이 알고 있는 수학적 지식에 대하여 의사소통 할 기회를 제공해 주며, 둘째, 학생들이 수학적으로 사고할 수 있게 하고, 셋째, 이런 수업을 위해 교사는 알맞은 분위기를 만들어 주어야 한다는 결론을 내릴 수 있었다.

The purpose of this study is to apply the principles of CGI(Cognitively Guided Instruction) into mathematics class in Korean elementary schools and to explore which mathematical concepts Korean students have and how they use informal knowledge and procedures to solve problems. In addition, this study tries to analyze difficulties that teachers might face when they are planning mathematics teachings based on CGI. The conclusions of this study are followings: First, the mathematics teaching based on CGI provides opportunity for students to communicate about mathematical knowledge that they know, The students are sure of their thoughts and learn from others by presentation. Second, the mathematics teaching based on CGI make students think mathematically. The students try to understand the meaning of problems and find various ways. Third, teachers should lead appropriate environment for the mathematics teaching based on CGI. They should offer proper problems and encourage their students to ask and answer questions respectively.
