物理习题教学中发现,学生在解题中遇到的许多问题,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,因此学生无法运用物理规律解题。从心理学的角度看,物理情景是指物理问题经过理性思考后在人脑中形成的关于物理现象、物理过程等的反映,即表象。物理情景不完全等同于物理现象,它有两层含义:一是具象,是人脑对具体物理现象形象化的反映;二是概象,是人脑对某一类物理现象经过抽象概括后形成
Physical exercises teaching found that many problems students encountered in the problem-solving, with the physical situation of the problem to establish and understand about. A lot of problems “hard ” is difficult in the physical situation is unclear, so students can not use the laws of physics to solve problems. From a psychological point of view, the physical situation refers to the reflection of the physical phenomena and the physical processes formed by the physical problems in the human brain after rational thinking, that is, the appearance. The physical situation is not exactly the same as the physical phenomenon. It has two meanings: one is the image, which is the reflection of the visualization of the specific physical phenomenon by the human brain; the other is the general image, which is formed by the human brain abstractly summarizing a kind of physical phenomenon
