Abstract

The purpose of this study is to analyze the conceptual simulation observed when students are thinking about the causes of the seasonal change, identifying how students come up with the explanation. For this study, a framework for conceptual simulation process and strategy based on literary research was developed and its validity was proved by four experts in the field of science education. The results were as in the following: First, through the process of explaining the causes for seasonal change, students usually base their explanation on perceptual experience learned from model experiments from a science class. Besides, construct of thought experiment using the familiar object or analogize of the familiar perceptual experience. These all contributed to on explanation firmly. Second, errors from mental simulation were found in the statement of initial representation and running imagistic simulation. It happened when statement of initial representation is not in a complete and secure state or when participants think of an inappropriate situation during running imagistic simulation. Third, the study identified that the use of strategies like 'removal' and 'replace' was shown to enhance the effects of conceptual simulation particularly in regard with solar attitude at meridian passage.

이 연구의 목적은 계절의 변화 원인을 설명하는 과정에서 초등학생들의 개념 시뮬레이션을 분석함으로써 학생들이 어떻게 계절의 변화 원인에 대한 설명을 어떻게 생성하고 있는지를 알아보고, 계절의 변화와 관련된 교육에 시사점을 주는 데 있다. 이를 위해 문헌 연구를 기반으로 개념 시뮬레이션 과정 및 전략 분석틀을 개발하였으며, 과학교육 전문가 4인의 내용타당도를 확인 받았다. 연구의 결과는 다음과 같다. 첫째, 계절의 변화 원인 설명 과정에서 초등학생들은 주로 과학수업에서 모형 실험을 통해 학습한 지각적 경험을 이용하여 설명을 만들고 있었으며, 친숙한 대상을 이용하여 사고실험 사례를 고안하거나, 친숙한 지각적 경험을 유추하여 설명을 확고히 하는 것을 돕고 있었다. 둘째, 개념 시뮬레이션 사례의 실수는 초기표상의 진술, 심상 시뮬레이션의 실행 과정에서 나타났으며, 참여자들의 초기표상 진술이 불완전하거나, 심상 시뮬레이션 실행에서 부적절한 상황을 떠올린 경우였다. 셋째, 초등학생들의 개념 시뮬레이션 과정에서 남중고도의 개념과 관련된 정신모델을 확고히 하기 위해 제거, 대체의 시뮬레이션 전략을 사용하는 것을 확인하였다.
