初中物理学习中常用的研究方法有多种,我们在光现象的学习中就用到了对比法、理想模型法、等效替代法等方法.下面进行具体介绍.一、对比法几个物理现象具有某种相同或者相异的性质,将它们放在一起进行比较分析,找出其异同点,可以帮助我们认清它们的内涵与外延,从而加深对知识的理解,进一步揭示事物的本质属性,这就是对比法.对比 Junior high school physics study commonly used in a variety of ways, we learn in the light phenomenon on the use of the contrast method, the ideal model method, the equivalent replacement method and so on.The following is a specific introduction.A comparison method Several physical phenomena have Some of the same or different nature, put them together for comparative analysis to identify similarities and differences, can help us recognize their connotation and extension, so as to deepen the understanding of knowledge and further reveal the nature of things, which Is the contrast method
