1.运用故事讲述呈现“数学背景知识”。在数学教学中,教师可以用讲故事的方式向学生呈现数学背景知识,引领学生走进数学的历史长河,追寻数学家的足迹,感受人类祖先智慧的结晶和数学的博大精深。例如在教学“圆的周长”时,可以向学生介绍魏晋南北朝时期的数学家刘徽创立“割圆术”的故事。在学习“圆周率”时,可以向学生讲述祖冲之把π值精确到七位小数,并以这一精度,在长达1000多年的时间里,一直处于世界领先地位
1. Using story telling presentation “math background knowledge ”. In mathematics teaching, teachers can present students mathematical background knowledge by means of storytelling, lead students into the history of mathematics, trace the mathematicians’ footsteps, experience the wisdom of human ancestors and the maturity of mathematics. For example, in the teaching of “circle circumference”, you can introduce students to the story of Liu Xi, a mathematician in the Wei, Jin, Southern and Northern Dynasties, and “Circumcision”. When learning Pi, you can tell the students about the value of π, which is accurate to seven decimal places. With this precision, it has been a world leader in more than 1,000 years
