Abstract

The purpose of this study was to identify the relation between preservice teachers' philosophical views on science and types of responses to alternative hypotheses. To identify preservice teachers' philosophical views on science, the extraterrestrial impact theory and the volcano-greenhouse theory, alternative hypotheses related to dinosaur extinction were administered to 37 elementary preservice teachers and 52 secondary preservice teachers. Subjects were required to write down their ideas before and after reading the alternative hypotheses, and then the dimensions of responses to initial ideas were analyzed. To analyze, Soh's Philosophical Perspectives Prove(PPP) was used. The results of this study were as follows: (a) elementary and secondary preservice teachers' philosophical views on science corresponds to eclecticism, (b) the main types of responses were partial theory change in elementary preservice teachers and rejection in secondary preservice teachers, (c) preservice teachers' philosophical views on science and types of responses were eclecticism-partial theory change in elementary preservice teachers and eclecticism-rejection in secondary preservice teachers.

이 연구의 목적은 예비교사들의 과학철학적 관점과 공룡의 멸종 관련 대안적 가설에 반응하는 유형과의 관계를 조사하는 것이다. 초등 예비교사 37명과 중등 예비교사 52명을 대상으로 하였으며, 예비교사들의 과학철학적 관점을 검사하는 도구로는 소원주 등이 개발한 PPP 문항을 이용하였다. 공룡 멸종에 관한 대안적 가설로는 공룡의 멸종 원인에 대한 여러 가설중 보편화된 운석 충돌설과 화산 온실설을 제시하였다. 먼저 예비교사들에게 공룡 멸종에 관한 대안적 가설을 읽기 전에 그들이 가지고 있던 생각을 조사하고, 대안적 가설 I(운석 충돌설)과 대안적 가설 II(화산 온실설)를 차례로 제시하여 읽게 한 후, 기존에 가지고 있던 생각에 대한 변화 정도를 조사하여 유형을 분석하였다. 연구 결과 예비교사들의 과학철학적 관점은 초등 중등 대부분 절충적 입장을 나타내고 있었으며 귀 납주의와 절충적 입장의 경계 및 반증주의와 절충적 입장의 경계에 해당하는 좁은 범위에 수렴하고 있었다. 초등 예비교사들의 경우 부분적 이론 변화에, 중등 예비교사틀의 경우 거부 반응 유형에 가장 많은 비율을 차지하고 있는 것으로 나타났으며, 초등 예비교사들은 절충적 입장인 경우 부분적 이론 변화에, 중등 예비교사들은 절충적 입장인 경우 거부 반응 유형에 높은 빈도를 나타내었다.
