“化学键”核心概念的教学分析——基于知识发展、教材编排、学生认知的三序结合视角

Teaching Analysis of the Core Concept of“Chemical Bond”Based on the Combination of Knowledge Development,Textbook Arrangement and Students’Cognition

“化学键”是中学化学教学中的核心概念之一,其有效教学是值得关注的话题。以学科知识发展、教材编排与学生认知发展的“三序结合”为研究视角,系统梳理“化学键”核心概念的教学内容,并构建“三序结合”教学模型。最后,基于“三序结合”对“化学键”核心概念教学提出相关建议。

"Chemical bond"is one of the core concepts in high school chemistry education.Effective teaching of"chemical bond"is a topic worthy of attention.From the perspective of combination of three order:development of subject knowledge,textbook arrangement and students'cognitive development,this paper systematically combs the teaching content of"chemical bond"and constructs a teaching model of"combination of three order".Finally,based on the teaching model,some suggestions are put forward for the teaching of"chemical bond".
