物理难学,是高中学生一种普遍的认识。课本上的公式、定理觉得掌握的很熟练,甚至可以倒背如流。但碰到具体的问题时,往往感到无从下手,一片茫然。长此以往,很多学生自信心大受打击,丧失学习物理的兴趣,物理成绩更是一落干丈。造成这种现象的原因我认为主要是不能把课本知识转化为自己的东西,不会把已有的知识向后继学习迁移,以至在新的物理情境下显得一筹莫展。那么,怎样才能提高应用物理知识的能力呢?“类比法”不失为一种行之有效的方法。正如前苏联学者瓦赫罗夫所说:“类比像闪电一样,可以照亮学生所学学科的黑暗角落。”
Physics is difficult to learn, is a common understanding of high school students. Textbooks on the formula, theorem that masters very skilled, or even backwards. However, when faced with specific problems, often feel unable to start, a loss. In the long run, many students have suffered a great deal of self-confidence and have lost their interest in studying physics. The reason for this phenomenon is that I think it is mainly because we can not convert the textbook knowledge into something else, and do not migrate the existing knowledge to the subsequent learning, even in the new physical situation. So, how can we improve the ability to apply physical knowledge? “Analogy” after all, is an effective method. As the former Soviet scholar Vajroff said: “The analogy, like a lightning bolt, illuminates the dark corners of the subject the student studies.” "
