英国著名物理学家牛顿说过“没有大胆而放肆的猜想,就不可能有伟大发现”。数学教育家G·波利亚也指出:要成为一个好的数学家……你必须首先是一个好的猜想家。”这两句至理名言道出猜想的重要性。更令人值得欣慰的是近几年中考命题在这方面进行了有益而大胆探索改革,为推动素质教育,培养学生创新能力,指导教学改革起到良好导向作用。本文选取近几年中考题加以剖析与读者共赏。
Well-known British physicist Newton said that “without bold and unpredictable conjectures, there can be no great discovery.” The mathematics educator G. Polya also pointed out: To be a good mathematician ... you must first be a good guesser. “These two sentences of reasoning tell the importance of conjecture. What is even more gratifying is that in recent years the examination proposition has been useful and bold in exploring reforms in order to promote quality education, cultivate students’ creative abilities, and guide teaching reforms.” Good guidance effect.This paper selects the examination questions in recent years to analyze and share with readers.
