Abstract

In this paper, we analyzed curriculum materials on inequalities as regions. Constructs such as mathematical connections and curriculum articulation were used as a framework. As for articulation, our findings indicate the topic of inequalities as regions addresses meaningful subordinate mathematical thinking and skills that serve prerequisite to calculus. Regarding connections, mathematical concepts involving inequalities extend to multivariate calculus. One implication is, as an unintended consequence of curricular decision of 2015 Revised National Curriculum to teach the topic only in mathematical economics, students who plan to study STEM subjects in college but opt out of mathematics economics in high school may miss the key concept and naturally struggle to understand calculus especially the theory of multivariate function of calculus.

본 연구에서는 2015개정교육과정에서 '경제수학'으로 이동한 '부등식의 영역(inequalities as regions)' 단원과 미적분학 사이의 연계성 및 수학적 연결성을 분석하여 '부등식의 영역'이 미적분학의 중요한 선수학습개념이라는 논지를 제시한다. 교육과정의 연계성 측면에서 직업 교과에 포함된 '경제수학'을 학습하지 않고 이공계에 진학하는 학생들은 '부등식의 영역'의 절차적 개념적 지식의 부재로 인하여 미적분학에서 학습 위계의 '격차'를 경험할 가능성이 크다. 수학적 연결성의 관점에서는 '부등식의 영역'과 밀접한 연관이 있는 미적분학의 다변수함수 이론의 학습에 어려움을 느낄 수 있다고 판단된다.
