概念是建构知识大厦的基石。高中化学概念很多,掌握这些概念是学生进一步养成化学应用能力的基础。笔者对目前高中化学教学做了一次梳理,发现在化学概念教学中存在一些不足的地方,具体表现在:①对概念教学重视不够;②概念教学模式陈旧;③教学过于平面化,学生的兴趣没有被充分调动起来。为此笔者将认知灵活理论运用在高中化学概念教学中,取得了满意的效 The concept is the cornerstone of building a knowledge building. There are many high school chemistry concepts. Mastering these concepts is the foundation for further developing students’ ability to apply chemistry. The author did a review of the current high school chemistry teaching and found that there are some shortcomings in the teaching of chemical concepts: ① not enough attention to the concept of teaching; ② outdated concept teaching; ③ teaching is too flat, students’ interest is not Be fully mobilized. To this end, I apply the theory of cognitive flexibility in high school chemistry concept teaching and achieved satisfactory results
