发展学生的数学思维是数学教学的重要任务之一,它是人们用数学来发现并解决实际问题的一种大脑活动形式,在整个数学思维过程中,它是一个人大脑在不断加工与梳理的过程,所以需要一定的时间,不可能是一蹴而就的。但是目前,许多教师追求一种大容量的课堂,总认为在短短的四十分钟内能够教给学生更多的知识,学生的数学素养才能得到 The development of students’ mathematical thinking is one of the most important tasks of mathematics teaching. It is a form of brain activity in which people find out and solve practical problems through mathematics. In the whole course of mathematical thinking, it is the process in which a person’s brain continuously processes and combs Process, it takes a certain amount of time, can not be accomplished in a single action. However, at present, many teachers are pursuing a large-capacity classroom and always think that they can teach their students more knowledge in just 40 minutes, so that students’ mathematical literacy can be obtained
