提高教学质量的核心问题是培养学生分析问题和解决问题的能力,有人认为教的知识越多,练的题目越难,学生的能力就会越强.甚至脱离教学大纲的要求,增加学生的负担,这种做法显然是不妥当的.下面我们以一个气体状态变化问题的教学为例,谈点体会. The core problem of improving the quality of teaching is to cultivate students’ ability to analyze problems and solve problems. Some people think that the more knowledge is taught, the harder the topics are, the stronger the students’ abilities will be, and even the requirements of the syllabus will increase the burden on students. This practice is obviously not appropriate. Here we take a teaching of the gas status change problem as an example to talk about experience.
