物理概念是从物理现象和事实中抽象出来的,是物理定律、公式和学说的基础.如果学生没有理解物理概念,就不可能进一步学习和掌握物理定律和公式,所以讲清物理概念对提高中学物理教学质量有着十分重要的意义.如何进行物理概念教学呢?这是一个值得物理教师交流的问题.下面结合笔者在教学中的体会,谈谈对磁感应强度的教学.一、从两方面拓展磁感应强度的教学磁感应强度是“磁场”一章很重要的一个物理概念,现
Physical concepts are abstracted from physical phenomena and facts and form the basis of laws of physics, formulas, and theories.If students do not understand physical concepts, it is impossible to further study and master the laws and formulas of physics, so to clarify the concept of physics to improve secondary schools Physics teaching quality has very important meaning.How to carry on the physics concept teaching? This is a question that the physics teacher exchanges.Consider the author in the teaching experience, talk about the magnetic induction intensity teaching.First, expands the magnetic induction from two aspects The strength of teaching Magnetic induction is a very important physical concept of “magnetic field”
