Abstract

The purpose of this study is to identify the types and characteristics of elementary school pre-service teachers revealed in the process of resolving the change of lunar phases, which emphasizes the context of actual observation, and to provide suggestions for areas to be considered in the elementary school teacher training program. To this end, we analyzed the 30 pre-service teachers' explaining the observable lunar phases, and the main research results are as follows. First, the phase change of the moon was often explained by introducing the timetable for each phase of the moon rather than based on observation of the phenomenon and scientific reasoning. Second, an alternative concept of the type that the moon is invisible when the sun rises or that the moon can always be observed has been identified. Third, there was a case of explaining that the time and orientation for observing the moon can be observed regardless of the position of the sun or when observing the sun. Also, the date of observing the moon was assumed to be approached by assuming the lunar calendar. Based on the above results, pedagogical implications were discussed.

이 연구의 목적은 실제 관찰의 맥락을 강조한 달의 위상 변화 문제를 해결하는 과정에서 드러나는 초등 예비교사의 설명 유형과 그 특징을 파악하여 초등 교사 양성 프로그램에서 고려해야 할 부분에 대한 시사점을 제공하는데 있다. 이를 위해 초등 예비교사 30명이 관찰 가능한 달의 위상을 설명한 내용을 분석하였으며, 주요한 연구 결과는 다음과 같다. 첫째, 달의 위상 변화에 대해 현상의 관찰과 이에 대한 과학적 추론에 바탕을 두기 보다는 달의 위상별 출몰 시간표를 도입하여 설명하는 경우가 많았다. 둘째, 태양이 뜨면 달이 보이지 않거나 또는 달이 떠 있다면 무조건 달을 관찰할 수 있다고 생각하는 유형의 대안 개념이 확인되었다. 셋째, 달을 관찰할 수 있는 시각과 방위에 대해서는 태양의 위치와 무관하게 관찰할 수 있다거나 남중할 때 관찰할 수 있다고 설명하는 경우도 있었다. 또한 달을 관찰하는 날짜는 음력으로 상정하여 접근하는 방식도 볼 수 있었다. 이상의 결과로부터 교육학적인 시사점을 논의하였다.
