高一物理的“机械波”概念尽管是从水波、绳波等直观的日常现象入手,但由于其生成过程的复杂性,故学生仍感到很抽象,不易把握问题的本质。我在教学的过程中,基于概念,分别从“宏观”和“微观”两个角度加以阐述,发觉会产生较好的效果。 Although the concept of a high-physics “mechanical wave” is based on intuitive daily phenomena such as water waves and rope waves, due to the complexity of its generation process, students still feel abstract and difficult to grasp the essence of the problem. In the process of teaching, I have elaborated on the concept of “macro” and “micro” from two perspectives, and found that it would produce better results.
