Abstract

This study examines the influence of the bodily interaction with digital technology on meaning-making process in a mathematical activity. Increasing interest in the use of multi-touch dynamic digital technology has brought the movement of the body to the center of research focus in recent mathematics education literature. Thereby, we investigate the process in which the meaning of the density of rational numbers emerges around the bodily interaction on the multi-touch dynamic digital technology. We analyze a case of a small group of primary school students with microethnography. In the result, the students formed the higher level of meaning of the density, where the finger movement of zooming in-and-out played a crucial role throughout the meaning-maknig process.

본 연구는 수학적 활동에서 디지털 테크놀로지와의 신체적 상호작용이 수학적 의미 형성 과정에 주는 영향을 탐구하는 것을 연구 목표로 삼는다. 최근의 수학교육 연구는 역동적 환경과 멀티터치 입력의 결합에 주목하기 시작했는데, 이에 따라 신체적 움직임이 연구에서 적극적으로 고려해야 할 대상이 되었다. 이에 따라 이 연구는 유리수 조밀성의 수학적 의미가 형성되는 과정을 역동적 멀티터치 테크놀로지와 상호작용하는 신체의 움직임과 관련하여 살펴보고자 한다. 이를 위해 소규모 집단의 초등학생에 대한 교수실험 사례를 분석하며 미시 문화기술적 방법을 사용한다. 연구 결과, 주어진 활동을 통해 조밀성에 대한 더 높은 수준의 수학적 의미가 형성된 것을 확인할 수 있었는데, 이러한 의미 형성 과정 전반에 걸쳐 학습자가 터치패드를 이용하여 화면을 확대하고 축소하는 손가락 움직임이 결정적인 역할을 하는 것으로 드러났다.
