在物理的学习中,学生经常在理解所学知识时有一些疑问,比如:人眼有看的见的光和看不见的光,人耳有听得见的声音也有听不见的声音.为什么这些声音人耳听不见,我要是能听见就好了,在学习这些知识的时候学生即使“会了”但是往往吃不透,因为这些不是他亲眼所见或者亲耳所听的东西,老师的解释有时学生并不能使学生服气所以学习起来难免会有一些疙疙瘩瘩.本节课的教学内容为苏科版八年级物理第八章《力》第一
In physics, students often have some questions in understanding what they have learned, such as the light seen by the human eye and the invisible light, the audible and audible voices of the human ear, and why these The sound can not be heard in the human ear, and if I can hear it, the students will not be able to understand even when they learn this knowledge because they are not what they saw or heard with their own eyes. Of the explanation Sometimes the student does not make the student take the gas therefore to study inevitably will have some pimples.The teaching content of this class is Su Ke edition eighth grade physics eighth chapter “force” first
