본 연구의 목적은 지구과학의 YX 그래프 해석을 위한 학습 모듈을 개발하고 그 효과를 살펴보는 것이다. 이를 위해 지구과학의 YX 그래프 해석 능력 검사지를 제작하고, 43명의 고등학생을 대상으로 학생들이 YX 그래프 해석 과정에서 겪는 어려움의 원인을 분석하였다. 이를 바탕으로 지구과학의 YX 그래프 해석 능력을 향상시키기 위한 학습 모듈을 개발하였다. 개발한 모듈의 효과를 단일집단 사전사후검사를 통해 학습자의 YX 그래프 해석능력과 그래프 해석 관련 성취도가 향상되는지를 살펴보았다. 연구 결과 학생들은 그래프 해석 능력과 관련된 기본적인 개념(독립변인 종속변인 확인, 기울기 및 변화율의 분석 등)을 YX 그래프 해석에 적용하는데 어려움을 많이 겪고 있었다. 그리고 개발한 모듈은 학생들의 그래프 해석 능력과 그래프 관련 성취도를 향상시키는데 효과적이었다. 따라서 개발한 YX 그래프 해석을 위한 학습 모듈은 지구과학의 그래프 해석 능력이 부족한 학생들에게 매우 효과적인 보충학습자료로 활용할 수 있을 것이다.

The purpose of this study is to develope the learning module for analyzing the YX graphs of Earth Science and observe the results of the learning module. For the purpose, worksheets to check the capabilities of analyzing the YX graphs of Earth Science were made and a study was conducted to 43 high school students and then in the process of the experiment the reasons why the students have difficulties in analyzing the graphs has been studied. On the basis of the results the learning module was developed to improve the capabilities of analyzing the YX graphs of earth science. The effects of the learning module have been examined through one-group pretest-posttest design. Two aspects of the results were observed : One is whether the capabilities of analyzing the YX graphs of earth science and achievement related to analyzing the YX graphs. According to the results of the study, students had lots of difficulties in applying the basic concepts related to analyzing the YX graphs(independent variables, dependent variables, analyzing of inclination, rate of change etc.) to analyzing the YX graphs. The learning module developed to solve this problem has been proved to be effective in improving the capabilities of analyzing the YX graphs of earth science and achievement related to analyzing the YX graphs. As a result, the learning module developed to improve the capabilities of analyzing the YX graphs will be used as supplementary materials for the students who are poor at analyzing the YX graphs in Earth Science.
