对学生进行近代史、现代史及国情教育,对培养社会主义现代化建设者和接班人,具有深远的意义。如何使“两史一情”教育融进数学教学中,是值得探讨的重要课题。一、回顾辉煌成就,激起民族自豪感我们的祖先在数学方面的成就是显赫的。如公元3世纪,数学家刘徽,创造了“割圆术”从圆内接正六边形开始,每次分割把边数倍增,算到192边形的面积,得到π=(157)/(50)=3.14,又算
It is of far-reaching significance to educate the students about modern history, modern history and national conditions and educate the builders and successors of the socialist modernization. How to make “two histories and one empiricism” education into mathematics teaching is an important topic worth discussing. I. Reviewing brilliant achievements and arousing national pride The achievements of our ancestors in mathematics are outstanding. For example, in the third century AD, mathematician Liu Hui created a “circumcision” starting from a regular hexagon in a circle, doubling the number of edges for each division, and calculating the area of the 192-sided shape, giving π = (157) / ( 50) = 3.14, again
