摘　　要：使用开放性问卷与访谈法,测查了36名化学职前教师对大概念(本质、性质、形式、结构、功能)和大概念PCK(课程知识KoC、学生知识KoL、策略知识KoS、评价知识KoA)的认识状况。结果表明:(1)职前教师对大概念的认识虽较全面,但在大概念的提炼和层级结构的理解上不够准确和深入;(2)相较于初中课程,职前教师对高中课程内容更为熟悉,且对必修阶段教学主题的熟悉程度优于选择性必修阶段;(3)职前教师对KoL的认识主要是基于演绎推理得出,且聚焦于思维能力的不足,较少关注知识方面的困难障碍;(4)职前教师在大概念教学策略和评价方法上表现出一定的局限性,缺乏对大概念教学的针对性。据此对我国化学师范生教育及其研究提出相关建议。This study explored the perceptions of 36 pre-service chemistry teachers on"big ideas"(nature,properties,forms,structures,and functions)and their pedagogical application through an open-ended questionnaire and interviews.Specifically,it examined their understanding in relation to four domains:knowledge of curriculum(KoC),knowledge of learners(KoL),knowledge of instructional strategies(KoS),and knowledge of assessment(KoA).The findings revealed that:(1)Pre-service teachers demonstrated a comprehensive understanding of big ideas,yet they struggled to distill these concepts and lacked clarity regarding their hierarchical structure.(2)They were more familiar with senior high school content,displaying strorger comprehension of compulsory topics compared to elective ones.(3)Their understanding of KoL tended to be deductive,emphasizing deficiencies in students'cognitive abilities over knowledge-related challenges.(.4)They exhibited shortcomings in teaching strategies and assessment methods,with an absence of targeted approaches for teaching big ideas.The implications for pre-service chemistry teacher education are also discussed.
