The purpose of this study is to propose a framework for analyzing a mutually corresponding relationship between gestures and diagramming in constructing making mathematical meanings. To this end, this study analyzes the case of mathematics classes which aimed at recognizing the relationship between average and a statistical distribution through activities using diagrams. Findings indicate that several students performed informal mathematical thinking using gestures and diagrams about some diagrams without numerical information. Further, our analysis captures the way gestures and diagramming reveal new mathematical meanings and elaborates the role of gestures and diagramming to refine the meanings. This study also discusses in what ways researchers and teachers can use the framework to better understand various types of gestures and diagrams in mathematical thinking.

수학 학습 과정에서의 다이어그램의 역할에 관한 연구는 오랫동안 다양한 관점 아래에서 이루어져 왔지만 이러한 다양성에 관한 메타적인 논의는 충분히 이루어지지 않았다. 본 연구는 다이어그램과 수학 학습 사이의 관계에 대한 다양한 접근 방식의 이면에 있는 인식론적인 가정에 관한 체계적인 논의를 진전시키는 데에 목표를 둔다. 이를 위해 수학 학습에서의 다이어그램의 역할에 주목한 이론적·실증적 연구 사례들에 관하여 기호로서의 다이어그램을 바라보는 관점에서의 차이를 중심으로 고찰하였다. 연구 결과 기호로서의 다이어그램과 수학 사이의 관계성을 바라보는 다양한 관점을 구조-기반 관점, 맥락-기반 관점, 그리고 물질기반 관점으로 구분하는 틀을 도출하였다. 또한 각 관점의 연구들의 바탕에 놓인 인식론적인 배경과 다이어그램과 수학 학습 사이의 관계를 설명하는 방식에서의 차이를 확인할 수 있었다. 본고에서 제시한 틀은 수학 학습 현상에서의 다이어그램의 역할에 대해 접근하는 데에 있어서 연구자들이 어떠한 이론적 렌즈를 통해 현상의 어떠한 측면에 주목하였는지에 관해 조망할 수 있도록 해준다.
