一、学习内容的地位分析《化学反应原理》专题2及专题3是在学习了“必修1和必修2”之后,应用物质结构理论来指导化学反应原理的学习,是对反应原理内容知识的进一步深化。其中专题2中的化学反应速率与化学平衡,专题3溶液中的离子反应是中学化学重要的理论部分,这两个专题内容既是对高中化学必修1相关内容的提升和拓展,又是选修“化学反应原理”的重要基础。二、创设引导学生参与的生活情境 First, the analysis of the status of learning content “Chemical Reaction Theory” Topic 2 and 3 is the study of “Compulsory 1 and Compulsory 2 ”, the application of material structure theory to guide the learning of chemical reaction principle, is the reaction principle of knowledge Further deepening. Among them, the chemical reaction rate and the chemical balance in the special subject 2 are the theoretical part of the chemistry of the middle school in the special topic 3. The two special topics are not only the promotion and expansion of the relevant contents of the high school chemical compulsory 1, but also the optional “ Chemical Reaction Principle ”an important basis. Second, create a life situation to guide students to participate
