Abstract

The purpose of this study is to derive implications for the development of the next curriculum and textbooks by comparing and analyzing the textbooks of the 2015 revised high school mathematics curriculum <Mathematics for Economics> and social studies curriculum <Economics>. In the <Mathematics for Economics> textbooks, economic terms and function notations should be introduced. Additionally, the use of graphs for economic-related functions is different from the use of graphs in mathematics in the <Mathematics for Economics> textbooks. For these reasons, the usage of economic terms, function notations, and function graphs covered in the <Mathematics for Economics> textbooks were compared and analyzed with the usage in the <Economics> textbooks. In the <Mathematics for Economics> textbooks, economic terms that are highly related to mathematics are defined and presented. Contrary to the conventions of mathematics and economics, the function notations in the <Mathematics for Economics> textbooks were used inconsistently because uppercase and lowercase letters were mixed in the function notations. Function graphs in the <Mathematics for Economics> textbooks had differences in the range of values represented by the variables regarding axes and scaling. The <Mathematics for Economics> textbooks did not provide a mathematical interpretation of the translation or slope. In the course of <Mathematics for Economics>, it is necessary to specify considerations for teaching and learning, and assessment in the curriculum to promote students' understanding of mathematics and economics. The descriptions in the curriculum document and textbooks of <Mathematics for Economics> should be supplemented to provide learning opportunities for mathematical interpretation of economics-related contents.

이 연구는 2015 개정 고등학교 수학과 교육과정 <경제 수학> 과목과 사회과 교육과정 일반 선택 과목인 <경제> 과목의 교과서를 비교·분석하여 차기 교육과정 개발 및 교과서 서술에 시사점을 도출하는 데 목적이 있다. <경제 수학> 교과서에서는 경제 용어와 함수 기호를 도입해야 하며, 이 교과서의 경제 관련 함수에 대한 그래프 사용은 수학에서의 그래프 사용과 다르다. 이에 <경제 수학> 교과서에서 다루는 경제 용어, 함수 기호 및 함수 그래프의 사용방식을 <경제> 교과서와 비교·분석하였다. <경제 수학> 교과서에서 경제 용어는 수학과 연관성이 높은 경제 용어를 정의하여 제시하였다. <경제 수학> 교과서의 함수 기호는 수학, 경제학의 관례와는 다르게 함수 기호에서 대소문자가 혼용되어 비일관적으로 사용되었다. <경제 수학> 교과서의 함수 그래프는 축, 스케일링에 관해 변수가 나타내는 값의 범위에 차이가 있었다. 또한, <경제 수학> 교과서에서 도형의 평행이동이나 기울기에 관한 수학적 해석을 제공하지 않았다. <경제 수학> 과목에서 학생들의 수학, 경제에 대한 이해를 촉진하기 위해 교육과정 문서상의 교수·학습 및 평가에 대한 고려 사항을 구체화할 필요가 있다. <경제 수학> 교육과정 및 교과서에서 경제 관련 내용에 대한 수학적 해석의 학습 기회를 제공할 수 있도록 서술이 보완되어야 할 것이다.
