多年来自己在各年级的教学实践中作了一些探索,下面就谈一下做法和体会: 一、放手让学生实践,通过学生亲自动手,进行比较研究,找出科学规律,获得正确结论,全面深入地领会和理解概念。例:在初中化学中学生已学过盐类与盐类的复分解反应,到高二又学到了盐类的水解。学生以为强酸弱碱盐与强碱弱酸两种盐溶液相遇 Over the years, I have made some explorations in the teaching practice in all grades. Here are some tips and experiences to talk about. I. Let students practice and let students do hands-on comparisons to find out the laws of science and obtain correct conclusions. Understand and understand concepts. Example: In middle school chemistry, middle school students have learned about the metathesis reaction of salts and salts, and in the second year they learned about the hydrolysis of salts. Students think that the strong acid and weak alkali salt and the strong alkali and weak acid salt solution meet each other
