Abstract

The purpose of this study is to identify the composition elements and processes of the rock cycle that pre-service teachers in earth science field understand. Second-year students majoring in earth science were selected as research objects, all of whom attended teacher's university located in the southern region. The methods of arranging the composition elements of the rock cycle in a structured way and displaying the cycle direction through the arrow and describing the cycle processes in detail were applied. Pre-service teachers recognized 5 composition elements: magma, igneous rocks, sediments, sedimentary rocks, metamorphic rocks of the rock cycle and cycle processes was represented into 20 branches. The cycle type was analyzed by four criteria: linear, triangular, circular, complex, some pre-teachers did not complete the loop of the cycle or some showed incomplete understanding of the cycle structure simply displayed in one direction. The rock cycle is an important theme of the earth system education characterized by dynamism and complexity.

연구의 목적은 예비 지구과학 교사들이 이해하고 있는 암석 순환의 구성요소와 과정에 대해 밝히는 것이다. 남부 지역에 소재한 사범대학교 2학년에 재학하면서 지구과학 수업을 수강하는 25명의 예비교사들이 연구대상으로 선정되었다. 암석 순환의 구성요소들을 구조적으로 배열하고, 순환 방향을 화살표로 표시하고, 순환 과정에 대해 서술하는 방법을 적용하였다. 예비교사들이 이해하는 암석순환의 구성요소는 마그마, 화성암, 변성암, 퇴적물, 퇴적암의 5가지로, 순환의 과정은 20가지로 표현되었다. 순환의 유형은 선형, 삼각형, 원형, 복합형의 4가지 기준으로 분석되었으며, 일부 예비교사들은 순환의 고리를 완성하지 못하거나 한 방향의 단순한 순환 구조로 시스템적이지 못한 이해를 표출하였다. 암석 순환은 역동성과 복잡성으로 특징되는 지구계 교육의 주제로서 중요한 의미가 있다.
