在现实的教学中,经常会遇到这样的现象,随着数学学习的深入,数学学习成绩差的学生越来越多。有的家长会说,孩子小学时数学学得不错,但到了初中后,对于数学的学习却是越来越头疼,成绩越来越差。在这里我们排除学生的非智力因素及智力因素的影响,只是从数学的学习整个过程来谈谈如何学习数学和如何诊断学生数学成绩差的原因。因为只有明白数学的学习过程,才能知道数学在学些什么,才能知道学生数学成绩差的原因所 In the real teaching, often encounter such a phenomenon, with the deepening of mathematics learning, mathematics learning achievement poor students more and more. Some parents will say that children have good math in elementary school, but after they have been in junior high school, they are getting more and more headache in math learning and getting worse grades. Here we exclude the impact of non-intelligence and intellectual factors of students, just from the whole process of learning mathematics to talk about how to learn mathematics and how to diagnose the causes of poor students in mathematics. Because only understand the learning process of mathematics, can we know what maths learn, in order to know the reason of poor math performance
