化学与实验的关系密不可分,化学实验在化学教学中起到了非常关键的作用,是化学知识的“发源地”。在化学实验教学中,假如能够充分运用化学演示实验,就能够提升课堂效率。这也需要教师在教学中积极探索,充分发挥演示实验的辅助作用,采用学生喜闻乐见的形式,调动学生的积极性,使学生对化学产生兴趣。一、规范操作方法,保证演示实验的效果
The relationship between chemistry and experiment are inseparable. Chemistry experiments play a very crucial role in chemistry teaching and are the “birthplace” of chemical knowledge. In chemistry experiment teaching, if we can make full use of chemical demonstration experiment, we can improve classroom efficiency. This also requires teachers to actively explore in teaching, give full play to the auxiliary role of demonstration experiments, students love the form of aroused, to mobilize the enthusiasm of students so that students interested in chemistry. First, standardize the method of operation to ensure the effectiveness of demonstration experiments
