Abstract

In this paper, we analyzed the types of tasks presented in the 'Probability and Statistics' textbooks and how the cognitive competences required to perform the tasks provide students with opportunity-to-learn. To this end, the analysis of the 9 books of the 'Probability and Statistics' test textbooks according to the 2015 revised mathematics curriculum showed that the context-based tasks(CF type, RE type) ranged from 67.5% to 78.0% of the total number of tasks in each textbook, but the ratio of relevant and essential tasks related to real life is from 0.4% to 2.0%, it was found that most of the context-based tasks presented in the textbooks were disguised as real life materials. The cognitive competences of context-based tasks ranged from 29.6% to 50.0% in reproduction category, from 33.8% to 54.3% in connection category, and from 8.8% to 20.0% in reflection category. As a result, there was not enough opportunity-to-learn for students to experience reflective cognitive processes.

본 연구는 '확률과 통계' 교과서에 제시된 과제의 맥락 유형과 과제를 수행할 때 요구되는 인지적 역량이 학생들에게 어떠한 학습기회를 제공하는지 살펴보았다. 이를 위해 2015 개정 수학과 교육과정에 따른 '확률과 통계' 검정교과서 전체 9권을 분석한 결과, 맥락 기반 과제(CF유형, RE유형)는 각 교과서마다 전체 과제 개수의 67.5%부터 78.0%로 나타났지만 실생활에 연관된 본질적인 과제(RE유형) 비율은 0.4%부터 2.0%로 나타나 교과서에 제시된 대부분의 맥락 기반 과제는 실생활 소재를 위장한 과제임을 알 수 있었다. 그리고 맥락 기반 과제의 인지적 역량은 각 교과서마다 재생산(Rp)범주에 속하는 과제 비율은 29.6%부터 50.0%로 다양하게 나타났고, 연결(Co)범주 과제 비율은 33.8%부터 54.3%, 반성(Rf)범주 과제 비율은 8.8%부터 20.0%로 나타나 과제수행 시 학생들이 반성적 인지 과정을 경험할 수 있는 학습기회는 다소 충분하지 않음을 알 수 있었다.
