化学是一门以实验为基础的自然学科,通过实验,可以更加形象、直观地理解所学过的知识。在实验课教学中,我们却常常发现学生完成化学实验后,难于正确地描述化学实验的现象。分析其原因,问题出现在教师忽视了对学生化学实验描述的指导,导致学生在描述化学实验现象时不知道该描述些什么?怎样描述才是正确的?下面,我就谈谈如何指导学生正确地描述化学实验现象。一、学会观察化学实验现象的方法观察实验现象主要是指用眼看、鼻闻、耳听、手感等方式得到实验的现象。学会观察化学实验 Chemistry is a natural science based on experiments. Through experiments, you can understand the learned knowledge more intuitively and intuitively. In experimental class teaching, we often find that after students complete chemical experiments, it is difficult to correctly describe the phenomenon of chemical experiments. The reason for the analysis is that teachers have neglected the guidance of the student’s chemical experiment description, resulting in students not knowing what to describe when describing the phenomenon of chemical experiment and how to describe it correctly. Next, I will talk about how to guide students to correct Describe the phenomenon of chemical experiments. First, the method of learning to observe the phenomenon of chemical experiments Observation of experimental phenomena mainly refers to the use of the eyes, nose smell, ear, feel and other ways to get the experiment.
