Abstract

The purpose of the study was to investigate the change of students' conceptual structures about sedimentary rocks through the field trip. A semantic network analysis method was utilized to assess the change. An open-ended questionnaire was developed to assess high school students' knowledge of sedimentary rock including its definition, classification, formation process, and characteristics. Fifteen high school students participated in the field trip of this study. The text data were analyzed using the semantic network analysis method. Results are as follows. First, high school students' conceptual structures about sedimentary rocks were more expanded after the field trip. Second, students' conceptual structures formed a 'small world network' by combining the sub-clusters. Third, the size of students' conceptual structures was decreased after a few month of field trip. Nonetheless, the connection among the clusters remained the same.

본 연구의 목적은 언어네트워크분석을 이용하여 야외지질학습에서 학생들의 퇴적암에 대한 개념 구조 변화를 알아보기 위한 것이다. 이를 위하여 고등학생 15명을 대상으로 퇴적암에 대한 정의, 분류, 생성과정 및 특징을 묻는 개방형 문항을 개발하였으며, 이 텍스트 자료를 언어네트워크분석법을 통해 분석하였다. 그 결과 첫째, 야외지질학습을 통해 학생들의 퇴적암에 대한 개념 구조는 사전에 비해 사후에 크게 확장되었다. 둘째, 학생들의 개념 구조를 구성하는 하위 클러스터는 서로 긴밀하게 연결되어 있는 '작은 세상 네트워크'를 형성하였다. 셋째, 학생들의 개념 구조의 규모는 수개월이 지난 후 감소하였지만, 하위 클러스터의 연결 상태는 그대로 유지하고 있었다.
