《数学课程标准》强调让学生经历观察、实验、猜想、证明等数学活动,提高了对数学应用能力的要求.数学建模将在中学数学教学中越来越受到人们的重视,特别针对一些较难的选择题时,建模(特殊值法)尤为显得非常灵活多变.本人就自己在教学实践中所获得的心得,略谈两点.一、数学猜想1.特殊—分析—归纳—猜想—一般归纳是从特殊到一般的思维方法,通过对各类特殊情形的分析比较、正确归纳,有助于产生合理的猜想,在某个数学问题
The standard of mathematics curriculum emphasizes that students should go through mathematics activities such as observation, experiment, guess, proof and so on, which enhances the requirement of mathematics application ability.Mathematical modeling will get more and more attention in middle school mathematics teaching, especially for some difficult Of the multiple-choice questions, the modeling (special value method) is particularly flexible very much .I own experience gained in teaching practice, a little talk about two points. First, the mathematical conjecture 1. Special - Analysis - Inductive - Conjecture - General induction is from the special to the general way of thinking, by analyzing and comparing various special cases, correctly summarized, contribute to produce a reasonable guess, in a mathematical problem
