- W890503887 abstract "이 연구는 끊는점과 녹는점에 관련된 실험 장치를 교육과정의 변화와 교과서의 유형에 따라 분석하고, 중등 과학교사들을 대상으로 이에 관련된 실험값과 교과서에 제시된 값이 다른 경우에 대한 인식을 조사하였다. 그리고 분별 증류, 온도계 보정의 실험 장치와 실 험 결과에 대한 인식도 조사하였다. 연구 결과, 교유고가정과 교과서의 종류에따라 끓는점과 녹는점에 관련된 실험 장치의 유형은 다양하게 변화되어 왔으며, 교사들의 인식도 전공과 근무 학교에 따라 다양하게 나타났다. 또한, 많은 교사들이 분별 증류 실험에서 실험값이 교과서에 제시된 값과 다른 원인을 교과서 내용의 잘못이나 실험 자체의 문제로 인식하고 있었다. 그리고 중학교에서 온도계 보정의 필요성에 대한 교사들의 인식은 다양하게 나타났는데, 화학을 전공한 교사들이 비화학 전공교사들보다 온도계 보정 필요성에 대한 인식이 더욱 높았다. In this study, the experimental apparatus for boiling point and melting point in science textbooks of various curriculums were analyzed. Science teachers' views on the difference between the experimental value and the value written in textbooks were inquired, too. Their views on the experimental apparatus, nd results of freezing point,melting point, boiling point, fractional distillation, and thermometer calibration were also investigated. The results of this study showed that the types of experimental apparatus for boiling point and melting point were somewhat dif-ferent with science textbooks and curriculum. The teachers' views were also various according to their background. In the experiment of the fractional distillat ion, a large number of teachers recognized mismatch between the exper-imental value and the value written in textbooks as mistake of textbook contents or problem of experiment itself. The teachers of chemistry background take higher recognition of the requirement of thermometer calibration than those of non-chemistry background in middle school." @default.
