化学是以实验为基础的一门学科,中学化学实验室是进行实验教学的重要基地.加强实验教学是提高化学教学质量的重要环节,而努力做好实验室的管理工作,又是搞好化学实验的前提条件.银川一中是一所老学校,实验室设备比较好.实验室共有两名专职实验员,为全校以初三到高三二十一个教学班的实验教学服务,任务繁重.根据化学课对实验教学的要求,无论演示实验还是学生分组实验,都有逐年增长的趋势.要做好实验室工作,应该注意做到以下几点:
Chemistry is a discipline based on experimentation. The middle school chemistry laboratory is an important base for experimental teaching. Strengthening experimental teaching is an important part of improving the quality of chemistry teaching, and efforts to do a good job in laboratory management are also a good part of chemistry. Prerequisites for the experiment. Yinchuan Yizhong is an old school with good laboratory equipment. There are two full-time laboratory technicians in the laboratory, serving the whole school with experimental teaching from the third grade to the top three one twenty-one teaching classes. According to the requirements of chemistry classes for experimental teaching, both the demonstration experiment and the student grouping experiment have a tendency of increasing year by year. To do laboratory work, the following points should be taken care of:
