《义务教育数学课程标准(2011版)》指出:应把证明作为探索活动的自然延续和必要发展,使学生知道合情推理与演绎推理是相辅相成的两种推理形式.“证明”的教学应关注学生对证明必要性的感受,对证明基本方法的掌握和证明过程的体验.此外,还可以恰当地引导学生探索证明同一命题的不同思路和方法,进行比较和讨论,激发学生对数学证明的兴趣,发展学生思维的广阔性和灵活性.为实现上述目标,在平时的几何课堂教学 The Compulsory Education Mathematics Curriculum Standard (2011 Edition) states: Proof should be taken as a natural continuation and necessary development of the exploration activity to make students know that the co-rationality reasoning and the deductive reasoning are two forms of reasoning that complement each other. Should pay attention to the students ’feelings about the necessity of proof, the mastery of the basic methods of proof and the experience of the proof process.In addition, they can properly guide students to explore different ways of thinking and methods to prove the same proposition, make comparisons and discussions, arouse students’ Interest in the development of students thinking broadness and flexibility to achieve these goals in the usual geometric classroom teaching
