Effect of Proof Education through Informal Activities on the Proof abilities of Students in the Elementary Gifted Class

비형식적 활동을 통한 증명교육이 초등 영재학급 학생들의 증명 능력에 미치는 영향

The purpose of this study was to develop teaching-learning materials for informal activities geared toward teaching the nature and structure of proof, to make a case analysis of the application of the developed instructional materials to students in an elementary gifted class, to discuss the feasibility of proof education for gifted elementary students and to give some suggestions on that proof education. It's ultimately meant to help improve the proof abilities of elementary gifted students. After the characteristics of the eight selected gifted elementary students were analyzed, instructional materials of nine sessions were developed to let them learn about the nature and structure of proof by utilizing informal activities. And then they took a lesson two times by using the instructional materials, and how they responded to that education was checked. An analysis framework was produced to assess how they solved the given proof problems, and another analysis framework was made to evaluate their understanding of the structure and nature of proof. In order to see whether they showed any improvement in proof abilities, their proof abilities and proof attitude were tested after they took lessons. And then they were asked to write how they felt, and there appeared seven kinds of significant responses when their writings were analyzed. Their responses proved the possibility of proof education for gifted elementary students, and seven suggestions were given on that education.

본 연구는 초등 영재학급 학생들의 증명 능력 향상을 목적으로 증명의 본질과 구조를 경험할 수 있는 비형식적 활동 교수 학습 자료를 개발하고 이를 실제 현장에 적용한 사례들을 분석하여 초등학교 수준에서의 영재들을 위한 증명 교육의 가능성과 교육에서의 시사점을 제안하기 위한 것이다. 초등 영재학급 학생들은 비형식적 활동 교수 학습 자료를 통해 증명의 본질과 구조에 대한 기본적인 이해가 이루어졌으며 증명에 대한 중요성과 필요성을 인식하였다. 증명에 대한 흥미도도 높아졌지만 증명이 쉽다고 느끼지는 않았다. 학생들은 광고나 신문, 패러독스에서 가정을 분석할 수 있었으며, 자료 적용 후에는 어려운 증명 문제에 도전하고자 하는 의지를 보였다. 이를 바탕으로 영재학급 학생들을 대상으로 하는 증명교육의 시사점을 제안하였다.
