二、做好每一个实验要做好实验教学工作,有不少问题值得研究的,例如实验的备课,实验的准备工作,实验过程中的指导等,对于这些,这里不多赘述,今把我们注意到的三种形式的实验中比较突出的几个问题分述如下。 (一)演示实验要发挥演示实验应有的作用,我们认为必须注意下面几个问题: 1.要明确每一个演示实验的目的我们在研究每一个演示实验的时候,首先根据教学大纲和教材弄清楚这一个实验的目的是什么。例如高一的“合成法制取盐酸”的演示实验,我们认为通过这个实验,可以使学生具体了解盐酸合成的化学原理,了解在工业上的化学生产原理,还可以了解工业上 Second, to do a good job in every experiment Experimental teaching, there are many problems worthy of study, such as the preparation of the experiment, the preparation of the experiment, the guidance of the experimental process, for these, we will not go into details here, now that we Several notable issues in the three types of experiments noted below are summarized below. (A) demonstration experiment To play the role of demonstration experiments, we think we must pay attention to the following questions: 1. To clarify the purpose of each demonstration experiment When we study each demonstration experiment, first of all according to syllabus and teaching materials Clearly what is the purpose of this experiment? For example, the higher one “synthetic method of hydrochloric acid,” the demonstration experiment, we believe that through this experiment, students can make specific understanding of the chemical principles of hydrochloric acid synthesis, understanding of chemical production in the industry principles, you can also understand the industry
