美国某科技馆的墙上写着这样三句话:“我听过了,我忘记了;我看过了;就知道了;我做过了,就记住了!”在化学教学中,如何选好实验,用好实验,做好实验,充分发挥实验的探究功能,培养学生的科学探究能力,应成为化学教师教学研究的课题。一、科学探究的基本功——培养观察的能力化学是以实验为手段来研究物质及其变化的科学,是以观察物质及其变化为特征的,因此,在平时的化学实验中就要鼓励学生认真观察和记录实验现象。1.培养学生进行有目的观察观察是一种有目的、
There is such a sentence on the wall of a science and technology museum in the United States: “I have heard it, I have forgotten it; I have seen it; I have known it; I have done it, and have remembered!” , How to choose a good experiment, make good use of experiments, do a good job of experiment, give full play to the exploratory function of the experiment, and develop students’ ability of scientific inquiry should become the subject of teaching and research of chemistry teachers. First, the basic skills of scientific inquiry - to develop the ability to observe Chemistry is the means of experiment to study the matter and its changes in science, is to observe the material and its changes are characterized, therefore, in normal chemistry experiments to encourage students Carefully observe and record the experimental phenomenon. 1. To develop students for purposeful observation and observation is a purposeful,
