教学中发现,学生在学习中遇到的许多问题,都与对问题的物理情景建立、理解有关。很多难题“难”就难在物理情景不清,因此无法运用物理规律解题。对教学中的物理概念、规律理解不好,也与教师没有设立合适的物理情景进行教学有关。可以说,学生学习物理的第一步就是建立正确的物理 Teaching found that many problems encountered by students in learning, are related to the establishment and understanding of the physical situation of the problem. Many difficult “difficult” is difficult in the physical situation is unclear, it can not use the laws of physics to solve problems. The teaching of physics concepts, laws of understanding is not good, but also with teachers did not set up appropriate physical scenarios for teaching. It can be said that students first step in learning physics is to establish the correct physics
