走进物理,首先要走进生活,在生活中学习物理,更能使学生爱上物理。1.联系生活实际,引起学生对物理的兴趣。各门课程和生活联系都非常紧密,物理亦如此。讲凸镜时,我举了汽车后视镜的例子。因为汽车已经走进了千家万户,一般汽车的右侧后视镜就是凸镜,这是利用凸镜对光线的发散作用和成正立、缩小、虚像的特点,使视野范围扩大了,这就确保了行车安全。还有,一般轿车都安装有深色玻璃,这是利用了光的折射原理,深色玻璃可以折射一部分光
Into physics, we must first go into life, learning physics in life, but also enable students to love physics. 1. Contact with the reality of life, causing students interest in physics. Each course has a very close connection with life and the same is true of physics. Speaking of convex mirror, I gave the car rearview mirror example. Because the car has come into the tens of thousands of households, the right side of the car rearview mirror is the convex mirror, which is the use of convex mirror of the divergent effect of light and into orthographic, reduced, virtual image features, so that the field of vision expanded, which Ensure driving safety. Also, the general car is equipped with dark glass, which is the use of light refraction principle, dark glass can refraction part of the light
