有效审题是解题的先决条件,很多学生缺乏审题意识,随意看了一下就开始做,往往事倍功半。很多物理题目条件给出很隐晦,如果不仔细挖掘,联系已知整体分析,提炼出有用信息,就很难理解出题者用意,无法顺利解题。或者在解题时不能兼顾所有限制条件,就会使得解题思路出现漏洞,不能得到完美解题。因此,教会学生如何发掘隐含条件十分重要,这直接关系到解题的正确与否以及得分,对学生的物理成绩有很大影响。
Effective essay is a prerequisite for problem solving, many students lack awareness of essay, feel free to look at the beginning, often less effective. Many physical conditions are very obscure, if you do not dig carefully, contact the known overall analysis, extract useful information, it is difficult to understand the title of the intended purpose, can not successfully solve the problem. Or can not take into account all the constraints in solving problems, it will make the problem-solving ideas loopholes, can not be a perfect solution. Therefore, it is very important for the students how to explore the implicit conditions, which is directly related to the correctness and scoring of the questions and has a great impact on the students’ physical performance.
