上第一节课时,教材中就有一句话:“物理是一门以观察、实验为基础的科学。”强调了实验在物理教学中的重要性,并且第一节也从声、光、热、电、力等几个方面安排了一些有趣的实验,耳听为虚,眼见为实,通过实验揭开了探索物理奥秘的序幕,而演示实验作为探究物理知识的方式,在物理教学中占有较大的比重。因此,上好演示实验是非常重要的。一、上好演示实验要精心备课,准备好实验虽然实验允许失败,但作为演示实验,主要就是要通过实验
The first lesson, there is a sentence in the textbook: “Physics is an observation, experimental science.” Emphasized the importance of experiment in physics teaching, and the first section also from the sound, light Some experiments were arranged in several aspects, such as heat, electricity and force. Earned ears were empty, eyes see the truth, and opened the prelude to explore the mysteries of physics through experiments. As a way to explore the physical knowledge, Occupy a larger proportion. Therefore, it is very important to demonstrate the experiment well. First, a good demonstration of the experiment To carefully prepare lessons, ready for the experiment Although the experiment allows failure, but as a demonstration experiment, the main is to pass the experiment
