| Classroom practice is an important process in the classroom instructions, it plays the role of monitoring, consolidating and the feedback. We choose little but good practice, creative practice, which will make the students solve the practical problems easier and understand it best. In my opinion, only when the teacher grasps the design of practice and the method of solving problems, consider the understanding of her own students can she design a proper practice ,thus improving the students'abilities of grasping the basic knowledge and solving the practical problems, which can make the teaching of physics better.This article takes the modern pedagogy, the psychology as well as the teaching discussion of the physics department as the foundation, combined related research results, limited the improper practice, used the principles how to design the physical exercises to explore and attempt different kinds of physical exercises and analyze them .In order to expect this research to provide a useful reference on exercises teaching for the front-line teachers and can play a catalytic role. |
