化学课知识零散,计算烦琐,很多学生由于不了解学科规律,学习步履维艰,化学教师应该从课上课下两个维度深入思考,解决兴趣、习惯、方法等核心问题。 The knowledge of chemistry classes is fragmented and the calculations are cumbersome. Many students do not understand the rules of the discipline and are struggling to learn. Chemical teachers should think deeply about the two dimensions of the lesson and solve the core issues of interest, habits, and methods.
