82年我开始教化学。在教学中发现:清华附中的学生,文化基础知识较好,求知欲较强,有一定的学习能力。但同时存在一些问题:有的学生认为现在处于“知识爆炸”的时期,中学课本里的基础知识学了没有多大用,不安心于中学的基础学习。有的学生认为化学知识零碎,不如数学、物理学科具有科学性和逻辑性,对化学不感兴趣。还有的学生学习中习惯于听老师讲课,老师讲什么,他听什么,记什么,背什么,惰性较大,处于消极被动学习的位置,缺少钻研精神,不会自己获取知识。还有的学生,为了考大学,平时把精力放在对付各次考试,钻进习
In 82 I started teaching chemistry. In the teaching, it is found that students in the middle school of Tsinghua University have good basic cultural knowledge, strong curiosity, and a certain level of learning ability. But at the same time there are some problems: Some students think that now is in the “knowledge explosion” period, the basic knowledge in middle school textbooks is not much use, not at ease with basic learning in secondary schools. Some students think that the knowledge of chemistry is fragmented, not as scientific and logical as mathematics and physics, and not interested in chemistry. Other students are accustomed to listening to the teacher’s lectures, what the teacher says, what he listens to, what he remembers, what he carries, and the inertia he is in. He is in a position of passive passive learning, lacks the spirit of study, and does not acquire knowledge on his own. Some students, in order to enter university, usually devote their energy to dealing with various examinations and drilling habits.
