横波的形成与传播是机械波这一章的教学重点,也是教学难点。若采用常规的教学手段,教师只能采用图解的方式进行分步讲解,学生很难在短时间内理解,教学效果较差,为此笔者用Flash5.0制作了《横波的形成与传播》的课件,在教学中动态地演示横波的形成与传播,教学效果良好。同时,该?
The formation and propagation of transverse waves are the teaching focus of the mechanical wave chapter and are also difficult to teach. If conventional teaching methods are used, teachers can only use step-by-step explanations in a graphical manner. Students find it difficult to understand in a short period of time and teaching results are poor. For this reason, the author used Flash 5.0 to produce the “transformation and propagation of transverse waves”. The courseware demonstrates the formation and propagation of transverse waves in teaching dynamically, and the teaching effect is good. At the same time, what?
