实验化学课程的开设,对中学化学实验教学提出新的要求。针对实验化学中的实验教学实效,从以下几方面在实践操作的基础上提出几点看法与思考:琢磨教材,优选装置与方法;研读教材,精选实验药品;精细操作,选准浓度与用量;因异而动,控制时间与巧借媒体;精筛细选,删除个别实验。
The establishment of experimental chemistry courses puts forward new requirements for chemistry experiment teaching in middle schools. Aiming at the actual effect of experiment teaching in experimental chemistry, this article puts forward some opinions and reflections on the basis of practical operation from the following aspects: pondering textbooks, optimizing devices and methods; studying teaching materials, selecting experimental drugs; fine operation, selecting standard concentration and dosage ; Because of the different action, control the time and skill by the media; fine screen fine selection, delete individual experiments.
