南京师范大学数学与科学学院刘云章教授认为:“不讲数学思想的课,不是好课”。诚然,数学思想方法作为数学课程教学的灵魂与主线,从根本上决定着我们整个数学教学任务的成败。与此同时,“数”和“形”是数学课程最基本的研究对象,更是整个义务教育阶段数学课程的两条主线。而另一方面,数形结合思想作为数学中最基本的数学思想和思维方法,在整个义务教育阶段数学课程的学习与教学中具有不可替代的作用。如果数学老师能够在数学教学中适时渗透数形结合思想,那么数学
Nanjing Normal University, School of Mathematics and Science Professor Liu Yunzhang think: “Mathematics does not talk about the class, not a good lesson ”. Admittedly, as the soul and main line of mathematics teaching, mathematical thinking and methodology fundamentally determine the success or failure of our entire mathematics teaching task. At the same time, “number ” and “form ” is the most basic research object of mathematics curriculum, but also the two main lines of mathematics curriculum in the entire compulsory education. On the other hand, as the most basic mathematics thought and thinking method in mathematics, the combination of number and form has an irreplaceable role in the study and teaching of mathematics curriculum in compulsory education. If mathematics teachers can penetrate mathematical combination of mathematical and mathematical ideas at the right time, then mathematics
