所谓“猜想一证明”教学模式是指在教学过程中,在观察分析个别事实或特殊问题的基础上,归纳其中隐含的规律,猜想其一般问题的结论或规律,在初步验证猜想正确的基础上给予严格的证明,从而解决其一般问题的一种教学模式,其操作程序如图1所示.近几年,笔者在高中数学教学中,多次尝试运用“猜想二证明”教学模式,取得了较好的教学效果. The so-called “guess a proof” teaching mode refers to the teaching process, based on the observation and analysis of individual facts or special problems, based on the induction of the implied laws, the conjecture of the general conclusions of the problem or law, in the initial verification of the conjecture is correct Based on the strict certification given to solve their general problems of a teaching mode, the operating procedures shown in Figure 1. In recent years, the author in high school mathematics teaching, many attempts to use "guess two proof Teaching mode, and achieved good teaching results.
