초록

2015 개정 교육과정에서는 수학 교과 역량으로서의 문제 해결 능력을 함양하기 위한 교수 학습 방법으로 협력적 문제 해결과 수학적 모델링을 새롭게 제시하였다. 따라서 이에 대한 교사들의 이해를 지원하는 것이 필요하다. 본 연구에서는 협력적 문제 해결과 수학적 모델링을 수학 수업에 반영하여 구체적인 지도 방안으로서 문제 및 수업지도안의 개발, 필요한 교사의 역할을 제시하였다. 10차시의 문제 해결 과정에서 학생들은 스스로 수학적 모델을 구성하였고, 해결 방법을 공유하면서 모델을 수정 보완하였다. 특히 교사가 문제 해결을 공유하고 논의하는 과정을 명확히 안내하는 경우에 학생들이 서로의 해결 방법을 비교하고 자신의 해결 방법을 보완하는 모습이 보다 잘 나타났다. 연구 결과를 토대로 수학 교과 역량으로서의 문제 해결 능력을 함양하기 위한 지도 방안에 대한 시사점을 논의하였다.

The purpose of this study is to support the understandings of teachers about the instructional strategies of collaborative problem solving and mathematical modeling as presented in the 2015 revised mathematics curriculum. For this, tasks of the Cubes unit from six grader's and lesson plans were developed. The specific problem solving processes of students and the practices of teachers which appeared in the classes were analyzed. In the course of solving a series of problems, students have formed a mathematical model of their own, modifying and complementing models in the process of sharing solutions. In particular, it was more effective when teachers explicitly taught students how to share and discuss problem-solving. Based on these results this study is expected to suggest implications on how to foster students' problem solving ability as mathematical subject competency in elementary classrooms.
