华东师范大学的尹筱莉老师曾在《论中学化学学科观念及其培养途径》一文指出:“随着学生走出校门走向社会,他们对化学知识等事实材料的记忆逐渐淡化甚至忘却。我们难以发现其脑海中还有多少化学观念和思想在指导其行动。”事实上,并不只是走向社会的人,有些就是还正在学习化学和从事化学工作的人在看待和解释生活中的化学现象时,也常常会表现出缺乏应有的化学意识和观念。我的一位朋友曾告诉过我,在他们学校有一位化学教师组织学生搬实验室时,一学生把一大瓶溴洒在楼道,顿时整个楼道被“黄雾”笼罩着,教师、学生慌忙逃散,无人处理,就连一些最简单、最基本的方法,如 Yin Xiaoli, from East China Normal University, once pointed out in his article “On the Discipline of Chemistry in Middle School and Its Cultivation Approach”: “As students go out of school and go to society, their memory of factual materials such as chemical knowledge is gradually diminished or even forgotten, and we can hardly find out In fact, not only people who are going to society, but also those who are still learning chemistry and working in chemistry, when they look at and explain the chemical phenomena in their life, Often it shows the lack of proper chemical awareness and concepts. One of my friends once told me that when a chemistry teacher in their school organized a student to move to the laboratory, a student splashed a large bottle of bromine onto the corridor and suddenly the entire corridor was shrouded in ”yellow mist". Teachers and students Hurriedly escaped, no one to deal with, and even some of the most simple and most basic methods, such as
