Abstract

The purpose of this study was to explore $6^{th}$ graders learning progression for lunar phase change focusing astronomical systems thinking. By analyzing the results of previous studies, we developed the constructed-response items, set up the hypothetical learning progressions, and developed the item analysis framework based on the hypothetical learning progressions. Before and after the instruction on the lunar phase change, we collected test data using the constructed-response items. The results of the assessment were used to validate the hypothetical learning progression. Through this, we were able to explore the learning progression of the earth-moon system in a bottom-up. As a result of the study, elementary students seemed to have difficulty in the transformation between the earth-based perspective and the space-based perspective. In addition, based on the elementary school students' learning progression on lunar phase change, we concluded that the concept of the lunar phase change was a bit difficult for elementary students to learn in elementary science curriculum.

이 연구의 목적은 초등학교 6학년 학생들의 달의 위상 변화에 대한 학습 발달과정을 천문학적 시스템 사고를 기반으로 탐색하는 것이다. 선행 연구 결과 분석을 통해 서답형 문항을 개발하고 가설적 학습 발달과정을 설정하였으며, 이를 토대로 문항 분석틀을 개발하였다. 달의 위상 변화에 대한 수업을 실시하기 전과 후에 서답형 문항을 이용한 검사 자료를 수집하였으며, 평가 결과를 이용하여 가설적 학습 발달과정의 타당성을 검증하였다. 이를 통하여, 상향식으로 지구-달 계에 대한 학습 발달과정을 탐색할 수 있었다. 연구 결과, 초등학생들은 지구 기반 관점과 우주 기반 관점 사이의 사고 전환에 어려움을 겪는 것으로 보인다. 또한, 달의 위상 변화에 대한 초등학생들의 학습 발달과정을 근거로 할 때, 달의 위상 변화의 개념은 교육과정 상에서 초등학교의 학습 내용으로 다소 높은 수준인 것으로 판단된다.
