在我所教过的初三、高一和高二的三个年级化学课的过程中,常发现某些章节的实验与我们学校的具体情况不符合,或者缺乏实验,如果教师不设法解决,自然会使学生在接受知识时感到观念和概念的抽象和模糊,以致不能巩固。为了避免这些缺点,下面举几个例子来谈谈我个人制作教具的粗浅体会,作为同志参考。 During the third grade chemistry class I have taught in the third, the first and the second year, I often find that the experiment of certain chapters does not accord with the specific situation of our school or the experiment is lacking. If the teacher does not try to solve it, Will make students feel the concept and concept of abstract and vague knowledge, can not be consolidated. In order to avoid these shortcomings, here are just a few examples to talk about my superficial experience of making aids, as a reference for my comrades.
