奇妙的化学实验把科学知识和典型美感熔化在一起,创造出大自然所没有的非常有趣的科学景观。这是化学学科的主要特色,是引起学生强烈兴趣的主要基因。但是,在化学教学实践中,我们往往是“身在美中不知美”。因此,化学教师如何发掘化学实验中美的因素进行审美教育,使学生在欣赏科学美的欢乐情境中轻松地学好化学知识,这是当前化学教改中一个值得认真探讨的问题。 美学家蔡仪先生认为:“美的东西就是典型的东西,就是个别之中显现着一般的东西。”在化学教学中,演示实验的选择原则就是要有典型性,这也是美的选择。选择的典型实验所发生的现象要使审美感觉器官得到满足,能产生美的感受。例如,镁条燃烧的眩目的炽白焰不光,点燃氢
The fantastic chemistry experiment melts scientific knowledge with typical aesthetics, creating a very interesting scientific landscape that nature does not have. This is a major feature of chemistry and a major gene that is of great interest to students. However, in the teaching of chemistry, we tend to be “unaware of beauty in the United States.” Therefore, it is an issue that should be seriously explored in the current chemical education reform that how chemistry teachers should explore the beauty of chemistry in chemistry experiments so that students can easily learn chemistry knowledge in the joyous atmosphere of enjoying the beauty of science. Aesthetics expert Cai Yi said: “Beauty is a typical thing, that is, what appears among the ordinary things.” In chemistry teaching, the choice principle of demonstration experiments is to have typicality, which is also the choice of beauty. The phenomena that occur in the typical experiment of choice are to satisfy the aesthetic sensory organs and produce a beautiful sensation. For example, the glittering blaze of magnesium flames ignites and ignites hydrogen
