实验的趣味性可以激发学生学习物理的兴趣,实验的直观性可以加深学生对物理概念和规律的记忆,实验的导向性可以启发学生的主动思维,实验的可信性可以强化学生对概念和规律的正确认识。一、尽量联系学生身边的实物如“摩擦”一节,可以让学生这么做,把手放在桌子上轻轻地向前推手时不觉得费力;如果把手紧压在桌子上再推的话就很吃力了。这样学生就很容易理解:压力
Experimental fun can inspire students to learn the interests of physics, the intuitive experiment can deepen students’ memory of the concept of physics and laws, the experimental orientation can inspire students’ active thinking, the experimental credibility can strengthen students’ concepts and laws The correct understanding. First, try to contact the physical side of the student, such as “friction ” section, allowing students to do so, hand on the table and gently push hands forward when not in trouble; if the handle pressed on the table and then pushed Very strenuous. This student is easy to understand: pressure
