본 연구의 목적은 학생들의 등식 이해 및 해결 전략에 대해서 교사가 얼마나 잘 예상하는지 탐색하는 것이다. 이를 위해 등호 이해 검사지를 개발하였고, 4학년 20개 학급을 연구대상으로 선정하였다. 각 학급의 교사에게 담당 학생들이 검사지 문항을 어떻게 해결할 것인지 다양한 전략을 예상하게 하고, 실제 학생 전략과 비교·분석하였다. 그 결과 교사들은 전반적으로 학생들의 계산적 전략과 관계적 전략에 대해서는 비교적 쉽게 예상할 수 있었던 반면, 학생들이 계산적 전략과 관계적 전략을 함께 사용하기도 한다는 점, 틀린 계산적 전략이나 틀린 관계적 전략을 사용하기도 한다는 점 등에 대해서는 충분히 이해하지 못하는 것으로 드러났다. 또한, 교사들이 예상한 것보다 학생들은 관계적 전략을 더 잘 사용할 수 있었고, 등식의 형태에 좀 더 영향을 많이 받는 것으로 나타났다. 이와 같은 연구 결과를 토대로 초등학교 학생들이 등호에 대한 관계적 이해를 진작할 수 있도록 교사에게 필요한 지식에 대하여 시사점을 논의하였다.
The purpose of this study is to explore how well teachers anticipate students to understand and solve equations. For this purpose, a questionnaire of the equal sign was developed, and 20 fourth-grade classes were selected as research participants. Teachers in each class were asked to predict various...
