一、教材分析现行苏教版《化学1》将氧化还原反应的知识分散在专题一第一单元第5面和专题二第一单元第44~46面,通过这两部分的教学,让学生知道如何区分氧化还原反应和非氧化还原反应,了解氧化还原反应的本质是反应中发生了电子的转移。能简单分析氧化还原反应,指出氧化剂和还原剂,标示出电子转移的方向和数目。二、教学设计导入:展示《中国诗词大会》剧照和主持人董卿及本季总冠军武亦姝照片,让学生体会:诗是浪漫的,化学是严谨的,这两者似乎格格不入。然而诗人却将严谨的化
First, the analysis of teaching materials The current version of the Jiangsu version of “Chemistry 1” spreads the knowledge of redox reactions in the first section of the first section of the first section and the first section of the second section of the first section from the 44th to the 46th. Through these two parts of the teaching, the students can know How to distinguish between redox reactions and non-redox reactions, understand that the nature of redox reactions is the transfer of electrons in the reaction. Simple analysis of redox reactions, pointing out oxidants and reducing agents, indicates the direction and number of electron transfer. Second, the introduction of instructional design: display “China Poetry Festival” stills and host Dong Qing and the season champion Wu Yijun photos for students to understand: poetry is romantic, chemistry is rigorous, both seem out of place. However, poets will rigorously
