Abstract

This study surveys how teachers can improve their understanding about the concept of declination only through reading the material presented as non-dipole magnetic model. This study also investigates a difference between the content of declination presented in "Earth Science II" textbook under the 2009 revised National Curriculum and that of the past one. Thirty teachers in Gyeonggi province and thirty three in the city of Seoul are surveyed; they are selected from the participants of required training that provides their first grade regular teaching certification. Findings of this study are as follows. First, the study finds that teacher participants possess several misconceptions about the declination. Their typical misconception show that a compass needle directly indicates the magnetic north pole. This type of misconception is not corrected only by a reading the material. Second, the study shows that the degree of teachers' understanding about the concept of declination improves through the reading the material of a non-dipole magnetic model. Third, the study reveals that the material of nod-dipole magnetic model is more effective with teachers than students. Finally, the study suggests that explanations including non-dipole magnetic model be revised in the current textbooks.

본 연구는 비쌍극자 모형이 제시된 읽기 자료만으로 교사들의 편각에 대한 이해도가 얼마나 높아질 수 있는지를 알아보았다. 그와 함께 2009 개정 교육과정 하의 "지구과학 II" 교과서에서 기술된 내용이 과거의 교과서 내용과 얼마나 차이가 있는지 알아보았다. 편각에 대한 이해도 조사는 1급 정교사 연수를 받고 있는 경기도 지역 교사 30명, 서울지역 교사 33명을 대상으로 이루어졌다. 연구 결과 첫째 교사들도 편각에 관한 여러 오개념을 가지고 있었으며 대표적으로 나침반 바늘이 자북극을 가리킨다고 하는 오개념이 있었다. 이러한 오개념은 읽기 자료만으로도 잘 수정되지 않았다. 둘째로 비쌍극자 모형이 포함된 읽기 자료를 통해 편각에 대한 이해가 높아졌으며, 셋째로 개발된 자료는 학생들에 비해 교사들에게 더욱 효과적임을 통계적인 방식으로 확인하였으며 마지막으로 현재 사용되고 있는 교과서에서 제시되고 있는 비쌍극자 모형이 포함된 설명도 보완 수정이 필요함을 알았다.
