现在很多学生反映初中物理难学,而学生认为物理难学的根本原因,主要是对基本概念难以理解,或难以理解透彻,以至于听不懂或不会用,更不要说灵活运用.因此我们认为:要使学生学好物理、灵活地应用物理知识解决实际复杂的物理问题,抓好物理概念的教学是关键. Nowadays many students reflect that junior middle school physics is hard to learn while students think that the fundamental reason why physics is hard to learn is mainly that it is difficult to understand basic concepts or can not be understood thoroughly or not, let alone flexible use. It is considered that: To enable students to learn physics well and flexibly apply physical knowledge to solve practical and complicated physical problems, it is the key to grasp the teaching of physical concepts.
