摘　　要：使用本土化的教学内容表征(CoRe)工具调查了46名接受"国培计划"的中学化学骨干教师关于"析氢腐蚀和吸氧腐蚀"主题的PCK,结果表明:(1)骨干教师的PCK包含5个相互联系的组分,其中课程知识、学生知识以及策略知识均较为丰富。骨干教师能有针对性地选取化学学科专属的教学策略;(2)在教学取向方面,骨干教师在教学中发展与评价学生化学基本观念与学科核心素养的意识有待加强,引导学生自主建构学习的落实程度有待提高;(3)在评价知识方面,评价方式较为多元,但骨干教师对于形成性评价的重视程度不够。文末据此对我国化学教师教育以及化学PCK研究提出相关建议。The PCK of "hydrogen corrosion and oxygen corrosion" of 46 high school elite chemistry teachers who participated in the "national training program" was investigated by using the localized content representation tool. The results showed that:(1) The PCK of elite teachers consisted of five interrelated components. Among them, knowledge of curriculum, knowledge of learners and knowledge of instructional strategies were relatively rich. Elite chemistry teachers could select subject-specific strategies for chemistry teaching;(2) Regarding orientation toward science teaching, elite chemistry teachers’ awareness of developing and evaluating students’ fundamental beliefs about chemistry and the core literacy in the classroom needed to be strengthened, and the degree of implementation of guiding students’ constructive learning needed to be improved;(3) As to knowledge of assessment, various approaches of assessment were suggested, whereas the formative assessment was not stressed by the teachers. Subsequently, suggestions for the chemistry teacher education in China and chemistry PCK research were provided.
