著名科学家牛顿有句名言 :“没有大胆的猜想 ,就不可能有伟大的发现和发明 .”猜想不仅能培养学生的创新意识 ,也能培养学生的创造性思维 .数学解题更离不开猜想 ,这一点在历届高考试题中常常体现出来 .然而 ,在目前中学数学教学中往往偏重于演绎推理的训练 ,强化形式论证的逻
Well-known scientist Newton famously said: “Without bold speculations, there can be no great discoveries and inventions.” The conjecture not only cultivates students’ sense of innovation, but also cultivates students’ creative thinking. Mathematical problem solving is more inseparable from guesswork. This point is often reflected in previous high test questions. However, in the current middle school mathematics teaching, emphasis is placed on deductive reasoning training, and the logic of formal argumentation is strengthened.
