Abstract

The purpose of the study is to analyze the levels of cognitive demands and components of the reasoning process presented in the mathematical sequence section of three high school mathematics textbooks in order to provide implications for the development of reasoning tasks in the future mathematics textbooks. The results of the study have revealed that most of the reasoning tasks presented in the mathematical sequence section of the three high school mathematics textbooks seemed to require low-level cognitive demands and that low-level cognitive demands reasoning tasks required only a component of one reasoning process. On the other hand, only a portion of the reasoning tasks appeared to require high-level of cognitive demands, and high-level cognitive demands reasoning tasks required various components of reasoning process. Considering the results of the study, it seems to suggest that we need more high-level cognitive demands reasoning tasks to develop high-level cognitive reasoning that would provide students with learning opportunities for various processes of reasoning, and that would provide a deeper understanding of the nature of reasoning.

본 연구의 목적은 향후 수학교과서의 추론 과제 개발에 대한 시사점을 제공하기 위하여, 고등학교 수준 수학교과서 3종을 연구 대상으로 수열 단원에 제시된 추론 과제의 인지적 난이도 수준과 추론 과정 구성요소를 분석하는 것이다. 연구 결과, 3종의 수학교과서의 수열 단원에 제시된 추론 과제의 대부분이 인지적 난이도 수준이 낮은 것으로 나타났으며, 인지적 난이도 수준이 낮은 추론 과제는 하나의 추론 과정 구성요소만을 요구하는 것으로 나타났다. 반면에 추론 과제의 일부만이 인지적 난이도 수준이 높은 것으로 나타났으며, 인지적 난이도 수준이 높은 추론 과제는 다양한 추론 과정 구성요소를 요구하는 것으로 나타났다. 이러한 연구 결과를 바탕으로 인지적 난이도 수준이 낮은 추론 과제보다는 학생들에게 다양한 추론 과정의 학습기회를 제공하고 추론의 본질을 심도있게 이해시킬 수 있는 인지적 난이도 수준이 높은 추론 과제 개발에 대한 필요성을 제시하였다.
