物理学科实践性、抽象性、应用性强,如何使物理问题形象化是学生学习的关键,直接影响课堂教学质量。尽管物理教师做了大量的演示实验,尽管我们将理论联系实际进行了讲解,但有时因实验条件的限制、物理知识的抽象性和复杂性,学生无法观察清楚实验的操作过程及实验现象,难以理解抽象的物理问 The physics discipline is practical, abstract and applicable. How to visualize physical problems is the key to student learning, which directly affects the quality of classroom teaching. Although physics teachers have done a lot of demonstration experiments, although we have explained the theory in relation to reality, sometimes due to the limitations of experimental conditions and the abstractness and complexity of physical knowledge, students cannot observe clearly the experimental process and experimental phenomena.
