笔者在从事中学理科仪器、药品管理工作中发现,一方面实验教师认为某些任课教师随意安排实验,不能按学生分组实验提前7d和教师演示实验提前3d的要求下发通知单,由此造成实验课太集中,实验教师任务重,课前准备仓促,课后任课教师和学生整理不到位,剩余药品不能及时处理而导致水质污染等问题;另一方面,任课教师认为存在教学任务重,课时紧,不能定期做实验等问题。为此,笔者结合中学理科实验室的实际情况,谈谈实验课的注意要点,供大家参考。
The author found that in the middle school science instrument and drug management work, on the one hand, the experimental teacher thought that some teachers randomly arranged experiments and could not issue notices according to the requirements of the student grouping experiment 7 days ahead of time and the teacher demonstration experiment 3 days ahead. The lessons were too concentrated, the task of the experimental teachers was heavy, the preparations were hurried before class, the teachers and students after class did not finish well, and the remaining medicines could not be dealt with in time, causing problems such as water pollution. On the other hand, teachers thought that there was a heavy task and the class time was tight. , can not do regular experiments and other issues. To this end, the author combines the actual situation of the science laboratory of middle school and talks about the points of attention of the experimental class for your reference.
