习题课是化学教学中的一项十分重要的内容,旨在通过习题巩固所学知识,查漏补缺,是教师检验教学效果和掌握学情的重要手段.但在平时的教学中很多教师不重视习题讲评课,认为讲评习题就是纠正答案,就题论题,这种教学往往枯燥无味.正是因为这种原因才出现许多老师经常抱怨“某道题我都讲了多少遍,很多学生还是错,现在的学生真的笨.”实际上出现这种现象的原因主要是由教师的教学方法造成的.要想上好习题课,要充分准备,精心备课,既要照顾大多数学生又要兼顾 Exercise class is a very important content in chemistry teaching. It aims to consolidate the knowledge learned through the exercises and to find out what is missing.

The problem-solving class commented that it was correcting the answer to the problem and that it was boring and boring. It was because of this reason that many teachers often complained that “I have spoken many times about a question, and many students are still wrong. The students are really stupid now.” The reason that this phenomenon actually occurs is mainly caused by the teacher’s teaching methods. To get a good problem class, you must be fully prepared and carefully prepared to take care of the majority of students.
