物理学是一门实验科学,物理概念的建立与物理规律的发现,都以实验事实为依据。实验是物理学的重要研究方法,只有重视实验,才能使物理教学获得成功,学生只有通过实验观察物理事实,才能真正理解和掌握知识。1.通过趣味新奇的物理实验演示,激发学生的好奇心理,从而激发他们思索的欲望例如,在讲授“大气压”一节时,可在装满水的杯上用硬纸片盖住并倒过来,发现水并不流出,纸片也不下落,使学生确信大气压的存在。接着让两个学生做马德堡半球实验,使他们感觉到巨大的大气压力,这样就会使学生对这节课感兴趣、印象深、易理解、记得牢。又如在讲授
Physics is an experimental science, the establishment of the concept of physics and the discovery of the laws of physics, are based on experimental facts. Experiment is an important research method in physics. Only by focusing on experiment can physics teaching be successful. Students can truly understand and master knowledge only through experimental observation of physical facts. 1. Inspire students’ curiosity by exciting novel experimental experiments. For example, when teaching “Atmospheric pressure,” you can cover a cup filled with water with cardboard and On the other hand, we found that the water did not flow out and the pieces of paper did not fall, making the students confident of the existence of atmospheric pressure. Then let the two students do the Maddox hemispheric experiment, so that they feel a huge atmospheric pressure, so that students will be interested in this lesson, impressed, easy to understand, remember the prison. Another example is teaching
