光电效应是现行高中物理下册第八章《光的本性》的重点内容。搞好“光电效应”的教学,不仅能使学生对光的粒子性有较深刻的认识,而且还能培养学生的辩证唯物主义观点和辩证的思维方法。下面谈谈我在“光电效应”教学中的几点做法和点滴体会: 一实践是认识的基础演示实验光电效应现象是学生不太熟悉的课题,因此,我就先演示了光控开关的实验(过程略),使学生了解光电效应现象和它的应用,以获得初步的感性认识从而激发学生进一步探索这一规律的热情和积极性。
The photoelectric effect is the key content of Chapter 8 “Light’s Nature” of the current High School Physics Book. Doing a good job of teaching the “photoelectric effect” can not only enable students to have a deeper understanding of the particle nature of light, but also develop students’ dialectical materialism and dialectical thinking methods. Let’s talk about some of my practices and experiences in the teaching of “photoelectric effect”: A practice is the basis for understanding The phenomenon of the demonstration experiment Photoelectric effect is a subject that students are not familiar with, so I first demonstrated the light control switch. The experiment (process omitted) enables students to understand the phenomenon of the photoelectric effect and its application in order to obtain preliminary perceptual knowledge and to stimulate students to further explore this law of enthusiasm and enthusiasm.
