化学实验是化学教学中教师传授知识,学生获取知识的重要途径。相信在教学工作中任何一位化学教师都不会轻视实验教学这一环节。但是,在具体实施每个实验的时候,大多还是采用的“照本宣科”、“照方抓药”的方法。这种方法的教学效果虽然不可否认,但也不能说是十全十美。笔者在教学实践中发现,化学课本中的实验无论是装置的组装、仪器的选用还是
Chemistry experiment is an important way for teachers to impart knowledge and acquire knowledge for chemistry teaching. I believe in chemistry teaching any chemical teacher will not despise this part of experimental teaching. However, in the actual implementation of each experiment, most of them still adopt the method of “according to the subject” and “according to the prescription”. Although the teaching effect of this method is undeniable, it can not be said to be perfect.
