Abstract

In this study, we developed education materials using history of science related to the experiment of 'Boyle's air pump' and the Boyle and Hobbs' debate of vacuum to find out the perceptions of NOS by pre-service chemistry teachers. For the study, 29 pre-service chemistry teachers at a college of education in Chungcheongbuk-do were selected. As RFN items that were related to the contextual situation developed in this study, items in the categories of 'Aims and Values', 'Scientific practices', 'Scientific Methods among Educational Applications' and 'Social-Institutional Aspects among Educational Applications' were selected. Through the items of RFN, the perceptions of pre-service teachers in non-contextual situations were investigated. Then we presented the pre-service teachers with the situation related to Boyle's experiment on air pump and Boyle and Hobbes' debate over vacuum. In addition, their perception of NOS was examined in contextual situations related to RFN items. Responses to the items, experimental results related to Boyle's Law, group discussion, and interview data were collected as data. As a result of the study, it was found that pre-service teachers had informed perceptions in most of the items, but cases with naive views or mixed views were found in context experimental situations. This study can contribute to the NOS education for pre-service chemistry teachers by development of context situation education materials related to NOS and by finding out their perceptions in the non-contextual and contextual situation.

이 연구에서는 비맥락적 상황과 맥락적 상황에서 예비화학교사들의 과학의 본성에 대한 인식을 비교하기 위하여 보일의 공기 펌프 실험과 이를 둘러싼 보일과 홉스의 진공에 관한 논쟁에 대한 과학사 소재를 개발하였다. 이 연구를 위하여 연구대상으로 충청북도에 있는 사범대학 재학 중인 예비화학교사 29명을 선정하였다. 이 연구에서 개발한 맥락적 상황과 관계가 있는 RFN 문항으로 '목표 및 가치', '과학적 기능', '교육적 응용 중 과학적 방법', '교육적 응용 중 사회-제도적 측면' 범주의 문항을 선정하였다. 그리고 RFN의 설문 문항을 통해 비맥락적 상황에 대한 예비교사들의 인식을 알아보았다. 그 후 예비교사들에게 보일의 진공 펌프 실험과 보일과 홉스의 진공에 관한 논쟁에 관련된 상황을 제시하였다. 그리고 RFN 문항과 관련된 맥락적 상황에서 예비교사들의 NOS 인식을 알아보았다. 자료로는 설문에 대한 응답과 보일의 법칙에 관련된 실험 결과, 조별 토론 자료, 인터뷰 자료 등을 수집하였다. 연구 결과, 비맥락적 설문의 대부분 항목에서 예비교사들은 정보에 입각한 견해를 가진 것으로 나타났으나, 맥락적 실험 상황에서는 순진한 견해나 혼재된 견해를 가진 사례들이 발견되었다. 이 연구는 NOS 관련 맥락적 상황의 교육 자료를 개발하고, 비맥락적 상황과 맥락적 상황에 대한 예비교사들의 인식을 파악함으로써 예비화학교사들을 위한 NOS 교육에 기여할 수 있다.
