Alternative Conceptions of High School Students about the Crust and Interior of the Earth

지각과 지구 내부에 대한 고등학생들의 대안 개념

Abstract

This purpose of this study was to analyze high school students' alternative conceptions and understanding levels about rocks, crust, plate tectonics and interior of the Earth. Data were collected through surveys, drawing assignments, and interviews. A total of 158 high school students in the first grade were involved in this study. The results showed that students have lots of major alternative conceptions which are meaning and forming process of rock, distinction of continental crust and ocean crust, formation and disappearance of ocean crust, movement of plate, continental drift, activities of volcano and earthquake. Physical and chemical characteristics, including mantle and core state could be found through analyzing from drawings.

본 연구는 암석, 지각, 판구조론 그리고 지구 내부에 대하여 학생들이 어떠한 대안 개념을 가지고 있으며 이해 수준을 보이고 있는지 분석한 것이다. 이를 위하여 설문과 드로잉 과제를 이용하였으며, 아울러 다양한 질문안을 통하여 면담을 병행하여 실시하였다. 연구는 고등학교 1학년 158명의 학생들을 대상으로 진행되었다. 결과에서 학생들은 연구 영역에 대하여 많은 대안 개념을 지니고 있는 것으로 확인되었다. 주요 대안 개념들은 암석의 정의와 생성 과정에 대한 이해, 대륙 지각과 해양 지각의 지형적 성분상의 구분, 해양 지각의 생성과 소멸과정에 대한 이해, 판과 대륙의 이동 여부와 원인, 화산 지진 활동의 발생 원인과 장소 등에 관련된 내용들에서 나타났다. 그리고 드로잉에서 분석된 대안 개념은 핵과 맨틀의 상태를 포함한 지구 내부의 물리·화학적 특성의 구분에서 나타났다.
