高考物理越来越重视学生认知能力的考察,每年高考都有很多针对这方面题目,让考生解答,但实际效果并不理想,其主要原因就是在常规教学中没能很好的强化训练和培养,物理学是一门自然科学,研究对象遍及整个物质世界,每个个体的运动比较复杂,面对具体问题,如何正确认识其物理过程,构建物理模型,是中学物理教学的重点,也是难点。而物理模型的建立,最为关键的是要让学生对事物的运动规律有正确的认识,能抓住影响事物的重要因素,化繁为简形成理想的化的模型 College entrance examinations more and more attention to the cognitive ability of students, the college entrance examination each year there are many for this area, so that candidates answer, but the actual effect is not ideal, the main reason is that in conventional teaching did not well strengthen the training and Physical education is a natural science. The object of study is throughout the material world. Each individual’s movement is complicated. In the face of specific problems, how to correctly understand the physical process and construct the physical model is the key and difficult point of the physics teaching in middle school . The establishment of the physical model, the most crucial is to allow students to have a correct understanding of the laws of the movement of things, to seize the important factors affecting things, to simplify the formation of the idealized model
