师范生关于核心知识的PCK直接影响其专业能力的发展。以氧化还原反应这一学科内容为例,对化学师范生关于氧化还原反应的PCK状况进行研究可发现:专业基础课程帮助师范生形成PCK基本结构;教学论课程促进师范生对学科知识和课程知识的理解;师范生的PCK子内容发展存在不均衡性;现有教师教育课程在学生知识方面存在不足。 Normal students on the core knowledge of PCK directly affect the development of their professional ability. Taking the subject of redox reaction as an example, the study on PCK status of redox reaction in chemistry students shows that the basic course of specialty helps PCL students to form the basic structure of PCK; the teaching theory promotes the students’ knowledge of subject and curriculum ; There is imbalance in the development of PCK sub-content in normal students; the current teacher education curriculum is deficient in student knowledge.
