The Application of Physical Model in Middle School Teaching

The physical model is an important carrier of the middle school physics knowledge. Starting from the definition of the physical model, the physical models can be divided into two broad categories, that is the ideal- ized models and the theoretical models. The application of physical models in physics teaching and the definition are elaborated by examples ; the application of physical models in teaching practice, is effective for students to con- struct knowledge, and is helpful to strengthen students＇ ability to solve problems. Finally, this paper emphasizes that the usage of the physical models has certain conditions and the scope, and the physical models are developing and changing
