物理学是一门实验科学,要尽可能安排学生亲自动手做分组实验或亲眼观察教师的演示实验,不能用教师讲实验来代替.教师对物理现象最清晰的讲解,也不能代替学生对实物和现象的直接观察.学生在学物理时,对一些物理现象和物理规律不甚理解,在思想上存在疑虑.如果教师可以根据当节课内容的多少和时间的松紧安排学生或自己动手做演示实验,既能开拓学生的眼界,又能解开学生思想上的疑虑,
Physics is an experimental science, as far as possible to arrange students to do group experiments or witness the teacher demonstration experiment, can not be replaced by teachers talk about the experiment.Teachers the most clear explanation of physical phenomena, can not replace students in kind and physical The phenomenon of direct observation.Students learn physics, some physical phenomena and physical laws do not understand, there are doubts in thought.If the teacher can according to the class content and the time of the tight arrangement of students or DIY demonstration experiment, Both students can broaden their horizons, but also solve the student’s thoughts on the doubts,
