所谓隐含条件,就是在题目中未明确表达出来、而客观上存在的条件。隐含条件隐藏得较深的题目,往往给学生造成条件不足的假象,但如果能仔细分析、推敲,就可以将其挖掘,使问题获得解决,这就要求教师在平时的教学中,注意引导学生挖掘数学问题中的隐含条件,使学生形成全面、深入地把握各种信息的能力,逐步培养学生思维的深刻性,本文将举例说明如何挖掘和利用隐含条件来解题。
The so-called implied conditions are conditions that are not clearly expressed in the subject and exist objectively. Implicitly concealed topics have often given students an illusion of inadequate conditions. However, if they can be carefully analyzed and scrutinized, they can be tapped to solve the problem. This requires teachers to pay attention to guidance in peacetime teaching. Students find the implicit conditions in mathematics problems, so that students can form a comprehensive and in-depth ability to grasp all kinds of information, and gradually cultivate the depth of students’ thinking. This article will illustrate how to explore and use implied conditions to solve problems.
