化学是一门实验科学。而演示实验是化学教学最有效的方法之一。本文就化学演示实验的做法谈些浅见。一、演示实验的目的和要求一定要明确,教者必须做到心中有数,并交待给学生,演示前要做到: 1.向学生说明演示的题目; 2.向学生简要介绍实验装置; 3.指出要求学生注意观察的部分; 4.强调注意思考的问题; Chemistry is an experimental science. Demonstration experiment is one of the most effective methods of chemistry teaching. This article briefly discusses the chemistry demonstration experiment. First, the purpose and requirements of the demonstration experiment must be clarified. The teacher must be aware of it and give it to the student. Before the demonstration, it is necessary to: 1. Explain the topic of the demonstration to the student; 2. Briefly introduce the experimental device to the student; 3 Point out the part that requires students to pay attention to the observation; 4.
