Abstract

본 연구의 목적은 9학년 학생의 공간능력 차이에 따른 지구자전 개념을 알아보는 것이다. 광역시 소재 9학년 학생 83명중 천체의 공간운동 개념 평가(김기정, 1997)에서 개념 획득 정도가 비슷하면서 공간능력에 차이가 있는 남학생 2명과 여학생 2명을 각각 표집하여 질적 분석의 대상으로 삼았다. 연구 결과, 공간능력이 높은 학생일수록 개념이 올바르고 개념들을 입체적 공간으로 재구성하여 이해하였다. 공간능력이 낮을수록 개념이 불완전하고 단편적인 개념들을 암기하고 있었다. 성별에 따라서는 공간능력이 높은 남학생은 개념들을 간단 명료하게 표현하였고, 낮은 학생은 자전에 대한 방향을 일주운동과 연관시켜 해석하지 못했다. 반면에 여학생은 공간능력이 높을 때 개념들을 구체적으로 표현하였으며, 낮을수록 개념들을 입체적으로 표현하지 못하였다. 따라서 공간능력이 높은 학생은 문제 상황을 제시하여 스스로 해결할 수 있도록 하고, 낮은 학생은 현상들을 직접 관찰하여 쉽게 이해 할 수 있도록 학습 자료를 개발하여야겠다. 여학생은 공간을 입체적으로 조작해 볼 수 있도록 하고 남학생은 사물을 여러 관점으로 생각해 볼 수 있도록 교수 전략 및 학습 자료 등을 개발 한다면 천문단원의 공간능력이 향상되고, 개념 획득이 잘 될 수 있을 것이라 기대한다. The purpose of this study is to investigate student's Acquisition about the conception of the Earth Rotation between difference of their Spatial Sensibility. In this study, four students were selected out of 83 9th graders in Gwangju, Korea. The spatial sensibility test instrument was developed by the Korean Testing Center, and the test instruments of 'the movement of celestial bodies' were developed by Kim (1997). The results were as follows: Students with higher spatial sensibility understood precisely about the Earth's rotation in stereoscopic space. However, those with lower spatial sensibility failed to grasp the Earth's rotation and memorized it as fragmentary concepts. As for gender effect, male student with higher spatial sensibility explained the concepts clearly, while that with lower spatial sensibility has difficulty with the Earth's rotation in relation to the diurnal motion of celestial bodies. On the other hand, female student with higher spatial sensibility explained the concepts correctly in detail, while that with lower spatial sensibility had difficulty explaining the concepts in stereoscopic space. Therefore, students with higher spatial sensibility should be presented with problems in which they form their own solution. Those with lower spatial sensibility should be allowed to understand the phenomena intuitively. In developing teaching methods, female students should interact with the concepts in stereoscopic space directly, while male students should consider the celestial objects from various viewpoints. Then spatial sensibility in relation to the movement of celestial bodies would be expected to improve.
