上好第一节引言课。“良好的开端是成功的一半”,首先,通过书中的四幅图让学生知道物理学是研究关于力、热、光、电的现象以及它们的规律的科学。其次,通过实验让学生知道物理知识不仅有趣,而且是非常有用的。第三点尤其重要,必须知道学好物理的方法:(1)重视观察和实验。(2)勤 Good first introductory lesson. “A good beginning is half of success.” First, through the four pictures in the book, students are taught that physics is a science that studies the phenomena of force, heat, light, electricity, and their laws. Second, it is not only interesting but also very useful to let students know physical knowledge through experiments. The third point is particularly important. You must know how to learn physics: (1) Pay attention to observation and experimentation. (2) Diligence
