一、利用现代信息技术,有利于突破教学难点,培养学生抽象思维中学生的思维正处于抽象思维不断发展的时期,而数学知识又是极其抽象的。利用信息技术可以把静止图象变为动态画面,把问题的一种形式转化成另一种形式,起到变复杂为简单;变难为易;变抽象为具体的作用。有促进学生思维的纵深发展,增强学生的思维灵活性和深刻性。例如:七年级下用二元一次方程解决实际问题时,有一道题:已知某一铁路桥长1000米,今有一列火车从桥上通过,测得火车从开始上桥到完全过桥共用1分钟,整列火车
First, the use of modern information technology is conducive to breaking the teaching difficulties and cultivate students’ abstract thinking The thinking of middle school students is in a period of continuous development of abstract thinking, and mathematical knowledge is extremely abstract. The use of information technology can be static images into dynamic images, the problem of one form into another form, played complex as simple; difficult for easy; change abstraction as a specific role. Promote the development of student thinking in depth, and enhance students’ thinking flexibility and profoundness. For example, in the seventh grade, when solving a real problem with a linear equation, there is a problem: it is known that a certain railway bridge is 1000 meters long. Nowadays, there is a train passing through the bridge and it is measured that the train runs from the bridge on the bridge to the bridge 1 minute, the entire train
