本文主要介绍的是反例在数学中的作用.举反例是一种重要的反证手段.重要的反例往往会成为数学殿堂的基石.学会构造反例是一种重要的数学技能,应该成为数学教学的基本训练内容而渗透于教学过程之中.反例的重要性要想充分的发挥出来,关键还在于具体的作出所需的反例.至于反例的作法,也如证明一样,因题而异,方式多变.反例对于正确理解数学概念,牢固地掌握公式、性质、法则,培养学生的逻辑思维能力,预防和纠正错误,都能起到特有的作用.反例的产生有的是学生在学习中“冒”出来的,有的是是教师在教学中有意诱“引”出来的,还有的是教师在教学中直接提出来的.不管是以何种形式出现的反例,教师都要引导学生进行详尽的讨论、对比、分析,使学生得到启发,并得出正确的结论.
This paper mainly introduces the negative role in mathematics. A counterexample is an important means of proof. An important counterexample often become the cornerstone of the mathematical palace. Learn a counterexample is an important mathematical skills, it should be the basic training in mathematics teaching and osmosis in the teaching process. To give full play to the importance of counterexample is also a key example, needed to make the concrete. As for the negative approach, such as that, depending on the title, and various ways. A counterexample to the correct understanding of mathematical concepts, firmly grasp formula, nature, principle, to cultivate students' logical thinking ability, prevent and correct the mistakes, can play a unique role. Counterexamples produced some students in the learning of "risk" out, some of it is the teacher intends to lure "lead" in teaching, and the teachers in teaching directly out of. Whether the counterexample in any form, teachers should guide students to discuss, comparison, analysis, to enable students to be inspired, and draw the correct conclusion.
