爱因斯坦说过:“想象力比知识更重要.”猜想就是一种想象力,它是数学思维的一种重要形式.纵观数学发展史,很多的问题是从猜想开始的,如:歌德巴赫猜想、欧拉猜想、四色猜想等.它是解决数学理论自身矛盾和疑难问题的一条有效途径,是打开数学大门的钥匙.在中学数学教学中我们也可以引导学生大胆地猜想,这样对于学生学好数学以及培养学生的创造性精神有着很重要的意义.一、有利于激发学生的学习兴趣和增强学习动力 Einstein said: “Imagination is more important than knowledge.” Guess is an imagination, which is an important form of mathematical thinking.According to the history of mathematics, many problems start from the guess, such as : The Goldbach Conjecture, the Euler Conjecture, the Four-color Conjecture, etc. It is an effective way to solve the contradictory and difficult problems in mathematical theory and the key to open the mathematical door.We can also guide the students to boldly guess in the mathematics teaching of middle school, This is of great significance for students to learn mathematics and cultivate the creative spirit of students.One, is conducive to stimulate students’ interest in learning and enhance learning motivation
