Abstract

This study searched for the possibility of tangram activities through modifying the tasks of elementary school mathematics textbooks into content based open tasks. As a result of analyzing previous researches, it was confirmed the educational effect of the mathematical tasks transformation and the educational value of tangram activities. The analysis of the textbooks revealed that the tangram activities presented in the textbooks are likely to be at the level of play. It was tried to modify 2015 revised curriculum textbook-tasks into content based open tasks. Based on this study, it could be expected advantages of task modification such as improvement of teachers' expertise and expectation of diverse reactions of students.

본 연구는 초등 수학 교과서의 과제를 내용 기반 개방형 과제로 변형함으로써, 탐구를 위한 탱그램의 활용 가능성을 탐색하였다. 선행연구를 분석한 결과, 수학 과제 변형의 교육적 효과와 탱그램 활동의 교육적 가치를 확인하였으며, 교과서 분석을 통해 교과서에 제시된 탱그램 활동은 놀이 수준에 그칠 가능성이 있음을 확인하였다. 이에, 2015 개정 교육과정에 따른 교과서 탱그램 과제의 변형을 시도하였다. 연구 결과, 폐쇄형 과제를 개방형 과제로 변형을 시도해 본다면 교사의 전문성 향상과 학생들의 다양한 반응 등을 기대할 수 있었다.
