Abstract

The purpose of this study is to evaluate the content knowledge and problem solving process used by pre-service earth science teachers while discriminating faults on geological maps. For this, we collected and evaluated data on fixation duration and gaze plot, while pre-service earth science teachers (N=12) solved the problem on faults interpretation using an eye tracker (Tobii Pro Glass 2 model). The results were as follows. First, most of the pre-service earth science teachers know the concepts of the normal and reverse fault but they do not know the procedural knowledge essential for fault interpretation on geological maps. Second, the pre-service earth science teachers did not draw a geological cross-sectional map to interpret the fault on the geological map and interpreted the fault based on two-dimensional information collected from the geological map rather than three-dimensional information. Therefore, it is essential to improve the teaching and learning environment so that pre-service earth science teachers who will become earth science teachers in the future can learn procedural knowledge essential to comprehend natural phenomena including understanding natural phenomena. The results of this study can substantially help organize a new earth science curriculum or develop materials on teachers' education in the future.

본 연구의 목적은 예비 지구과학교사들이 지질도에서 단층을 판별하는 동안 그들이 사용하는 내용 지식과 문제해결 과정을 분석하는 것이다. 이를 위해 연구자들은 시선 추적기(Tobii Pro Glasses 2 모델)를 활용하여 예비 지구과학교사들(N=12)이 단층 해석에 대한 문제를 해결하는 동안 그들의 시선 고정 시간, 시선 경로에 대한 자료를 수집하여 분석하였다. 그 결과는 다음과 같다. 첫째, 그들은 정단층, 역단층, 주향이동단층 등에 대한 개념은 인지하고 있지만, 대부분의 예비 지구과학교사들은 지질도에서 단층 해석에 필요한 절차적 지식은 인지하고 있지 않다. 둘째, 예비 지구과학교사들은 지질도에서 단층을 해석하기 위해 지질 단면도를 그리지 않았고, 3차원적 정보가 아니라 지질도에서 수집한 2차원적 정보를 바탕으로 단층을 판별하였다. 그러므로 차후 교육 현장으로 진출하는 예비 지구과학교사들이 자연현상에 대한 이해와 더불어 그 자연현상을 이해하는데 필요한 절차적 지식을 학습할 수 있도록 교수학습환경을 개선할 필요가 있다. 그리고 본 연구의 결과는 차후 새로운 교육과정을 구성하거나 교사 교육에 대한 자료를 개발하는데 실질적으로 도움을 줄 수 있을 것이다.
