Abstract

The purpose of this study is to characterize students' conceptions on causes of the phases of the moon. For this purpose, students were given a worksheet for argumentative writing activity where in they need to choose the right answer between five statements and provide reasonable evidences about causes of the phases of the moon. Written arguments collected were used as analysis data and TAP(Toulmin's argument pattern) including conceptual analysis of TAP elements were utilized to figure out logical structures and subordinate conceptions. The result showed that students had various alternative concepts about causes of the phases of the moon and associated with celestial. Also 70.5% of subjects had incomplete argument structures, and error types of concepts had difference according to types of alternative concepts as well as TAP. These results mean that importance of checking students' preconceptions, need of scientific argumentation, and appropriate instructional strategies considering alternative conception types and fallacy types that students had.

이 연구의 목적은 논증 글을 통해 달의 위상변화 원인에 대해 학생들이 가지고 있는 개념의 특성을 파악하는 것이다. 이를 위해 달 위상변화 원인에 대한 대표적인 대안개념을 포함한 5가지 설명 중 옳은 것을 선택하고 근거를 서술하도록 하는 논증 과제를 투입하였으며, 학생들의 개념 선택과 근거의 TAP 구조 및 하위 개념을 분석하였다. 분석결과 학생들은 달의 위상변화 원인뿐만 아니라 관련 개념에서도 다양한 대안개념을 가진 것으로 나타났다. 연구대상의 70.5%가 불완전한 논증 구조를 보였으며, 대안개념의 유형에 따라 주로 나타나는 오류 유형이 다르다는 특징도 확인할 수 있었다. 이러한 결과들은 학생들이 지닌 선개념 점검의 중요성과 논증활동의 필요성, 대안개념의 유형에 따른 적절한 교육적 처방의 필요성을 나타낸다.
