很多中学生感觉物理难学,其症结之一就在于物理概念没有搞好.学生往往忽视对概念的理解,只注意背定义,记公式,做练习题,被数学符号淹没,概念不清越学越困惑,更谈不上知识的灵活运用.学生理解和掌握物理概念,是一个十分复杂的认知过程.在这一过程中,学生首先通过观察、实验获取必要的感性知识,接着用物理学方法,通过复杂的思维过程(分析与综合、比较、抽象与概括)把新事物与自己认知结构中原有 Many middle school students feel that physics is hard to learn and one of the cruxes lies in the fact that the concept of physics is neglected. Students often neglect their understanding of concepts. They only pay attention to the definition of backs, formulating formulas, doing exercises, being overwhelmed by mathematical symbols, , Let alone the flexible use of knowledge.Students understand and master the concept of physics is a very complex cognitive process.In this process, students first through observation, experiment to obtain the necessary perceptual knowledge, and then use the method of physics, Through complex thinking process (analysis and synthesis, comparison, abstraction and generalization) to new things and their own cognitive structure in the original
