Abstract

The types and the characteristics of students' responses to anomalous data in studying 'boiling point' were investigated, and the degree of cognitive conflict and conceptual change were compared by students' cognitive variables. Tests regarding field dependence-independence and logical thinking ability, a preconception test, and a test of responses to anomalous data were administered to 137 sixth graders. Among them, 90 students whose preconceptions were consistent with the presented initial theory were selected. After learning the scientific concept, students' conceptual change was examined. Six types of responses identified were as follows: Rejection, reinterpretation, exclusion, uncertainty, belief decrease, and theory change. The main responses were rejection (33%) and theory change (39%). The results of Mann-Whitney U test indicated students who were field independent and had higher logical thinking abilities felt more cognitive conflict and exhibited more conceptual change.

끓는점 개념에 관련된 변칙 사례를 제시했을 때 변칙 사례에 대한 학생들의 반응 유형을 알아보고 학습자의 인지적 수준(장의존독립성, 논리적 사고력)에 따른 인지 갈등 유발 정도 및 개념 변화를 조사하였다. 초등학교 6학년 학생 137명을 대상으로 장의존독립성 검사, 논리적 사고력 검사, 선개념 검사, 변칙사례에 대한 반응 검사를 실시하였고, 초기 이론과 일치하는 선개념을 가진 90명 의 학생들만을 선택하였다. 과학 개념 학습 후 학생들의 개념 변화를 조사하였다. 변칙 사례에 대한 반응 유형은 거부, 재해석, 배제, 판단 불가, 신념 감소, 이론 변화 등 6가지였으나, 대부분의 반응 유형은 거부 (33%)와 이론 변화(39%)인 것으로 나타났다. Mann-Whitney U 검증결과, 학습자가 장독립작일수록, 논리적 사고력이 높을수록 변칙 사례에 의해 인지 갈등이 많이 유발되며 개념 변화를 효과적으로 일으키는 것으로 나타났다.
