Abstract

The purpose of this study was to analyze system thinking revealed in science teachers' teaching practices of middle school astronomy classes. Astronomy lessons were video-taped from four eighth grade science teachers. The video recordings were all transcribed and analyzed by employing a framework for systems thinking analysis after modifying an existing frame of hierarchial structure used in relevant previous studies. In addition, four participants were interviewed in order to uncover their orientation toward teaching using video stimulated recall method. Findings are as follows: All participating teachers were not able to employ the four levels of system thinking appropriately and only utilized the low level of systems thinking. They also demonstrated teacher-centered practices for employing system thinking despite their student-centered orientation toward teaching. The main reason for these results may be that teachers focused more on spatial thinking, than on system thinking as well as the lack of teacher's knowledge about the content and formative assessment of non-earth science teachers. Implications on how to effectively employ the system thinking in astronomy class are discussed in this paper.

이 연구의 목적은 중학교 천문 수업에 대한 과학 교사의 교수 실행에서 나타나는 시스템 사고를 분석하는 것이다. 이를 위해 4명의 중학교 8학년 과학 교사의 천문 단원 수업을 녹화하였고 녹화된 수업은 모두 전사하였으며, 선행 연구의 시스템 사고 위계 구조를 수정하여 개발한 시스템 사고 분석틀을 적용하여 이들을 분석하였다. 또한, 수업 분석 후 참여 교사의 과학 수업에 대한 지향과 교수학적 생각을 심층적으로 분석하기 위해 비디오 자극 회상 면담을 실시하였다. 연구 결과는 다음과 같다: 모든 참여 교사들은 천문 수업에서 시스템 사고의 위계를 제대로 반영하지 못하였으며, 낮은 수준의 시스템 사고만을 활용하는 것으로 나타났다. 또한, 교사가 학생 중심의 교수 지향을 지녔다 하더라도 시스템 사고의 교수 실행은 교사 중심으로 진행되는 것으로 나타났다. 천문 수업의 교수 실행에서 시스템 사고가 부족하게 나타나는 것은 공간적 사고에 보다 집중하는 것과 지구과학 비전공 교사로서의 천문 내용 및 형성 평가 지식 부족 때문인 것으로 판단된다. 이러한 연구 결과를 바탕으로 천문 수업에서 효과적인 시스템 사고의 도입 방안을 논의하였다.
