物理是一门以实验为基础的学科。这几年笔者在物理教学中,有目的地安排设计一些对比性的实验和一些对比性实验视频,帮助学生形成正确的物理概念,掌握物理规律,突出重点,突破难点,消除疑点,收到了很好的教学效果。总听有些同学讲物理太难学了,其实物理之所以难就难在本质被现象遮住,比如:小学我们都学过地球绕着太阳转,这是本质;而我们每天都看到太阳从东边升起,从西边落下,感觉太阳总是围着我们转,这是现象。想要真正学好物理,想要透过现 Physics is an experiment-based discipline. In recent years, I have designed and designed some comparative experiments and some comparative experiment videos in physics teaching to help students form the correct physical concepts, grasp the laws of physics, highlight the key points, break through the difficulties and eliminate the doubt points, and received very Good teaching effect. Some students always listen to physics too hard to learn, in fact, the reason why it is difficult to physically obscure the phenomenon of nature are covered, for example: primary school we all learned the Earth around the sun, this is the essence; and we see the sun every day from The rise of the east, from the west, I feel the sun always turn around us, this is the phenomenon. Want to really learn physics, want to through now
