据心理学家研究,小学高年级的学生已经具备了一定的抽象思维能力,并且这一能力不弱于初一的学生。如果教师在这一阶段加强渗透数学思想,就能为学生学习数学知识打下良好的基础。现以小学加法和减法的教学为例,说明教师渗透数学思想的方法。一、数形思想的渗透数形思想,是一种把抽象的数学关系应用图形的方式呈现出来,在图形上研究数学问题的思想。心理学家认为,人们在面对抽象事物时,只能捕捉到事物中20%左右的信 According to psychologists, senior students in primary schools already have a certain degree of abstract thinking ability, and this ability is not weaker than the students in the first day. If teachers strengthen infiltration of mathematical thinking at this stage, they can lay a good foundation for students to learn maths. Now the teaching of primary addition and subtraction as an example to illustrate the teacher penetration mathematical ideas. I. Permeation of Numeric Ideals Numeric thinking is a way of applying abstract mathematical relations to a graph and studying the problem of mathematics on the graph. Psychologists believe that when people face abstract things, they can only capture about 20% of the things in the letter
