化学是从微观角度研究和理解化学物质性质和变化的科学.微观化、符号化是化学学科的明显特征.化学方程式中蕴涵着不少学科思想和学科规律,在高中化学课堂教学中进行必要的挖掘和深化,有利于凸显化学学科特色,有利于提高课堂教学效率,有利于构建高中化学智慧课堂.下面谈谈高中化学反应教学感悟.一、体现比较思想通过化学反应,可以比较物质的下列性质.
Chemistry is a science that studies and comprehends the nature and changes of chemical substances from the microscopic point of view.Microscopic and symbolic are the obvious characteristics of chemistry.The chemical equations contain many disciplinary ideas and discipline rules, Digging and deepening is conducive to highlight the characteristics of chemistry is conducive to improving the efficiency of classroom teaching is conducive to the construction of high school chemistry wisdom classroom.Considering the high school chemistry reaction teaching sentiment.First, reflect the comparative thought Through chemical reaction, the following properties can be compared .
