促进初中化学核心概念深层次理解的复习设计

Revision Design for Promoting Deep Understanding of the Core Concept of Chemistry in Junior Middle School

学习者对核心概念的理解水平直接影响其对整个学科的理解,如何促进化学核心概念的深层次理解,是化学教学一直研究的主题,根据化学学习三重表征的思维方式,以思维导图为表征手段,利用随机进入式教学模式,实现化学核心概念的深层次理解,进而实现化学学科理解。

The understanding of the core concepts directly affects the understanding of the subject. How topromote deep understanding of the chemical core concepts has been the research topic of chemical teaching. Ac-cording to the Triple Representation——the thinking mode in Chemistry learning, the method of thinking map istaken as the representation means, and the teaching mode of random entry is used. Adopting the random entryteaching mode will be helpful to the deep understanding of chemical core concepts in order to achieve understand-ing of Chemistry.
