비형식적 통계적 추리 교수·학습에서의 행위자-네트워크 분석

Abstract

This study started from a critical awareness of the ontological position of technology in mathematics teaching and learning. Based on the perspective of Actor-Network Theory(ANT), we consider teaching and learning as a network and focus on the agency that emerges from the combination of human actors and non-human actors. The results of research with comparing data sets tasks based on the concepts of distribution and sample with elementary school students in grades 5 showed that the key actors were teachers and students, technology such as graphs, diagrams, TinkerPlots, and the concepts of distribution and sample. Through the translation of these actors, it was possible to confirm how the network is constructed. Bar graphs interessement students through the length or color of the bars, dot plots interessement through an environment for drawing various diagrams, and TinkerPlots interessement through utilizing different functions. Non-human actors have changed students from focusing only on a single data to considering various aspects of distribution. In addition, students form a concept image of distribution and make a inference using representative values and distribution. This means that mathematical concepts are expanded and distributed among various actors in the mathematics teaching and learning network.
