作为主要以学生抽象能力进行计算、推导的高中数学学科,其明显不同于历史、政治等学科的特征就是,没有严密的思维活动就不会有学习过程的发生。而所有的思维活动都是从问题产生的,作为高中数学教师,其主要任务就是要让学生头脑中有问题,然后再通过判断学生的问题思考程度做必要的引导。在这个过程中,师生互动是十分必要的。因为只有互动,教师才会发现学生思考的程度与问题,引导起来才有理有据、富有成效。只有互动,才会督促学生做深入的思考与探索,直到达成教师设定的教学目标。因 As a high school mathematics subject mainly calculated and abstracted from students’ abilities, it is obviously different from history, politics and other disciplines in that there is no learning process without close thought activity. And all thinking activities are generated from the problem. As a high school mathematics teacher, its main task is to make students have problems in their minds, and then make the necessary guidance through judging students’ thinking problems. In this process, teacher-student interaction is very necessary. Because only interaction, teachers will find the extent and problems of student thinking, to guide only reasonable and productive. Only interaction, will urge students to do in-depth thinking and exploration, until the teacher set the teaching goals. because
