- 中文摘要: The purpose of this study was to explore the understanding of chemistry concepts in gas laws, conservation of mass, oxidation and reduction, and the function of salt bridge of a small group (N = 30) of physics, biology, and earth science teachers. While 32 chemistry teachers were attending an assessment workshop, four openended items were developed to determine the science teachers' understanding of the chemistry concepts. The initial findings revealed that considerable perportion of the science teachers possessed a high ratio of misconception in the domain of chemistry. Twenty three percent of the science teachers held misconceptions of the gas laws, 23% in the conservation of mass, 30% of the function of the salt bridge, and all of them had the misconceptions on the oxidation reduction reaction in the half-cell. The results indicated that our science teachers would not be ready to teach chemistry related courses if they were asked to do so. Extensive in-service training sessions are recommended to strengthen the science teachers' content knowledge before the implementation of the new curriculum in Taiwan that integrates biology, physical science, earth science, and technology into the single subject of "science and technology."
