厉行節約积累資金对我國發展国民經济的建設起着很重要的作用。因此,具体在化学教学中如何節約药品,避免浪費,也是值得注意的。下边是我校一年來在節約药品方面的一些經驗体会,提出供同志們参考。一、关於药品使用量的問題。我校自開展边講边实驗的化学教学以來,把9个班,分成90个实驗小组,药品的消耗量是相当大的。实驗时,一部分学生对药品的使用量,总有宁多勿少的偏向;因此,在使用药量時,經常具体交代,如固体药品用量,規定为1个火柴头大、2个黄豆大、1平匙、1小匙(指牛角匙的的另一
Practicing saving and accumulating funds plays an important role in the development of our national economy. Therefore, it is also worth noting how to save medicines and avoid wastage in chemistry teaching. The following is our school in the past year to save some experience in medicine, put forward for your reference. First, the use of drugs on the issue. Since carrying out the chemistry teaching that talks about experiments, our school divided 9 classes into 90 experimental groups and the consumption of medicines is quite large. Experiment, some students on the use of drugs, there is always more than do not tend to be less; therefore, when using the dose, often specific explanations, such as the amount of solid drugs, provides for a match big head, two soybeans, 1 flat spoon, 1 tsp (referring to the other one
