초록

이 연구는 과학적 모델을 적용한 두 차례 야외지질학습(관악산과 한탄강 형성과정)에서 학생들이 보여주는 표상적 능력에 대한 이해를 목적으로 하였다. 수도권 소재 대학부설 영재원 10명의 학생들이 자발적으로 참여하였다. 야외학습환경과 교실학습환경에서 학생들이 작성한 서면 자료, 수업 과정에 대한 모든 영상녹음 및 음성 녹음 자료, 수업 종료 후 면담 자료를 수집하였다. 표상적 능력 수준을 구분하는 분석틀로 학생들의 표상 능력의 단계를 구분하고 과학적 모델 형성 과정에서 표상적 능력의 수준과 최종모델과의 결과론적인 해석을 덧붙였다. 그 결과 학생들의 표상적 능력은 1~6수준까지 다양하게 나타났다. 다만, 학생들은 야외학습환경에서 교실학습환경보다 상대적으로 낮은 수준의 표상적 능력을 보였다. 즉, 야외학습환경에서 상대적으로 낮은 수준의 표상적 능력으로부터 시작되어 교실학습환경에서 학생들이 표상적 능력의 수준을 높인 것을 결과론적으로 보였다. 궁극적으로 학생들의 표상적 능력을 이해하는 것은 과학적 모델 형성과정에서 현상을 설명하기 위한 도구로써 학술적인 의미를 지녔다.

The purpose of this study was to understand students' representational competence while they engaged in learning in geological field trips with scientific models and modeling(Mt. Gwanak and the Hantan-river were formed). Ten students agreed to participate in this study voluntarily. They were attending the Institute of Gifted Education in the Seoul Metropolitan area. The data were collected for all students' activities during field trips and modeling activities using simultaneous video and voice recording, the interview after classes, written data(note) made by the students. The analysis framework that distinguished levels of representational competence and added the resulting interpretation with the final models in the process of scientific models. Results suggested that representational competence levels varied from one to six. However, students showed relatively low levels of representational competence in outdoor learning environments than indoor learning environments. In other words, it began with a relatively low level of representational competence in outdoor class. Then students developed a higher level of representational competence indoor class. Ultimately, we need to understand students' representational competence implies a tool to explain phenomena in the process of modeling activities.
