顾名思义,“题眼”就是题目的“点睛”之处,是题目中最关键的部分,好比人的眼睛是心灵的窗户一样,透过“题眼”能知道这个题目透露的最重要信息.那么物理的“题眼”是什么?它有哪些功能?又如何挖掘呢?下面笔者结合自己的教学实践,谈一些个人的看法,供同行参考.1什么是物理“题眼”中学物理习题中,总有这样类型的题目,涉及到的知识点多综合性强;已知条件被隐含,造成学生读不懂,不知从何处下手;有些题目看似简单,却易受表面假象的迷惑,不
As the name suggests, “title ” is the title “dot”, is the most critical part of the title, like the human eye is the soul of the window, through the “title” to know the subject revealed What is the function and how to dig it? The author combines my own teaching practice, talk about some personal views for peer reference.1 What is the physical “Problems” In the middle school physics exercises, there are always such types of topics, which involve more comprehensive knowledge points; known conditions are implicit, resulting in students do not understand, I do not know where to start; some problems may seem Simple, yet vulnerable to the surface of the illusion of confusion, no
