공간 감각 신장을 지원하는 초등수학 교수․학습의 방향성 탐색

Abstract

This study aims to explore the direction of elementary mathematics teaching and learning to support the development of spatial sense. For this purpose, tasks in elementary mathematics textbooks dealing with spatial sense were analyzed from the perspectives of spatial sense and levels of cognitive demands. The results showed that Korean textbooks provided tasks related to mental rotation, mental transformation, mental dimensional transformation, and positional sense in terms of spatial sense, and PNC, PWC, and DM tasks in terms of the levels of cognitive demands. In order to explore the direction of teaching and learning related to the spatial sense of three-dimensional shapes, we analyzed publicly available teaching and learning materials from IREM in France as an example of a task with distinctive features from the Korean textbooks tasks. Based on this analysis and discussion, implications were drawn for the direction of elementary mathematics teaching and learning that supports the development of spatial sense in terms of task development, curriculum, and teaching and learning methods.
