众所周知,物理题中的条件是解题的前提和根本。如何引导学生处理习题中的各种各样的条件呢?就本人在教学中的实践作一些简单的总结。一、挖掘隐含的已知条件某些习题的条件不是直接地告诉我们,而是隐含在题目之中,要我们用学过的知识去判断、分析,它可能是某一常数,某一等量关系,某一应熟记的物理量。若在审题中就能看穿,并加以挖掘,则问题就迎刃而解,手到题成。 As we all know, the conditions in the physics problem are the premise and root of the problem solving. How to guide students to deal with a variety of conditions in the exercise? On my own practice in teaching for some simple summary. First, mining the hidden conditions known Some of the conditions of the exercises are not directly tell us, but implicit in the title, we use the learned knowledge to judge, analyze, it may be a constant, a Equivalent relationship, a physical property should be memorized. If we can see through the trial, and to tap, the problem will be solved, hand to title.
