Abstract

This study was aimed to investigate how students' relational thinking about equations could be formed by exploring web-based balance. The researchers developed 3 groups of 4 typed 12 equation problems of (a+b+c = d+ _ ) to test 24 4th graders. Pretest and post-test were conducted using Eye-tracker for investigating their eye movements. The researchers interviewed students who were not having distinct strategies to look into their cognitive process. As a result, we can conclude web-based balance helped students to get the concept of the equal sign and to form the relational thinking by the process of comparing both sides, right and left on the basis of fulcrum on balance.

본 연구에서는 시선추적기(Eye-Tracker)를 활용하여 웹기반 저울 교수학습 프로그램을 이용한 대수적 실험이 학생들의 방정식에 대한 관계적 사고를 형성 시키는지를 학생들의 시선 움직임으로 확인하고자 하였다. 연구문제를 해결하기 위해 전주의 J초등학교 4학년 학생 24명을 대상으로 방정식(a+b+c=d+_) 문제를 3블록, 4가지 형식(12문항)으로 제시하여 시선추적기를 통해 사전사후검사를 실시하고 전략이 뚜렷하지 않은 경우는 면담을 실시하여 인지 과정을 살펴보았다. 수업은 웹기반 수저울 중심으로 등호에 대한 개념 이해와 관계적 사고가 형성되도록 짜여졌다. 그 결과 웹기반 수저울은 받침점을 기준으로 좌우를 비교하도록 하는 과제 해결과정에서 등호에 대한 개념 형성 뿐 아니라, 평형을 이루기 위해 좌우를 살피는 문제 해결과정을 통해 관계적 사고를 형성할 수 있었다.
