타원 작도에 대한 ｢기하｣ 교과서와 ｢지구과학Ⅱ｣ 교과서의 비교 분석

Abstract

Objectives The purpose of this study is to compare and analyze the meaning and method of ellipse construction of the ｢Geometry｣ and ｢Earth ScienceⅡ｣ textbooks of the 2015 revised curriculum.
 Methods To do this, an analysis framework for the meaning and method of ellipse construction was developed, and the contents related to ellipse construction of seven ｢Geometry｣ textbooks and four ｢Earth ScienceⅡ｣ text-books were analyzed in accordance with the analysis framework.
 Results First, seven ｢Geometry｣ textbooks and four ｢Earth ScienceⅡ｣ textbooks all suggested activities to mean drawing ellipse. Second, five ｢Geometry｣ textbooks presented the activity of constructing an ellipse using ruler and compass. Third, in the case of the ｢Geometry｣ textbooks, four presented a method of drawing using concen-tric circles, four presented a method of using origami, and five presented a method of drawing using pushpin and thread. Fourth, the same ellipse drawing activity was presented in the four ｢Earth Science Ⅱ｣ textbooks. All text-books presented activities to draw the elliptical orbit of Mars based on observation data, and methods of drawing using pushpin and thread.
 Conclusions Since the link between science, mathematics, information, and environmental curriculum is em-phasized, it is necessary to conduct a follow-up study on the curriculum linking mathematics and science based on the results obtained in this study. In addition, research on how to use mathematical technologies in science education has recently been conducted, so follow-up research on various teaching and learning method to con-struct an ellipse orbit such as using mathematical technologies, needs to be conducted in the ｢Earth ScienceⅡ｣ textbook.
