在数学教学过程中,从讲的角度,为了给学生留有更多的时间与空间,使学生掌握基础知识、培养基本技能,许多教师都做到了少讲,通过多留时间来让学生做更多的练习。但是,少讲是否讲到了位、是否讲到了关键,这是一个非常重要的问题,所以,在“讲”上,我们应做到精讲;从练的角度,为了使学生巩固基础知识、 In the teaching of mathematics, from the speaking point of view, in order to give students more time and space to enable students to master the basic knowledge and develop basic skills, many teachers have done less, by allowing more time for students to do more Practice. However, it is a very important issue whether we talk about the key or not. It is therefore a very important issue that we should do our utmost in respect of “lecturing”.
