在无数次的教材培训、听课、教学研讨活动中,多数的数学教师在课堂上没有抓住数学概念的核心进行教学,教学中没有贯穿始终的数学思想主线,学生经常在没有对数学概念和思想方法有基本了解的情况下就盲目进行大量的解题操练,这些现象导致了教学缺乏必要的根基,教学活动不得要领,在一些无关大局的细枝末节上耗费了许多宝贵时间.怎样才能突破数学教学的瓶颈,切实减轻学生过重的学习负担,提高教学的质量与效益呢?笔者认为课堂教学应在
In countless teaching materials training, lectures, teaching seminars, the majority of mathematics teachers in the classroom did not grasp the core of the concept of mathematics teaching, teaching did not run through the main line of mathematics, students often without the concept of mathematics and ideas Methods are basically blind to a large number of problem-solving exercises, these phenomena led to the lack of teaching the necessary foundation, teaching activities can not get the essentials, in some unrelated to the details of the minutiae spent a lot of valuable time. How can we break through mathematics teaching Bottleneck, and effectively reduce the students overburdened learning burden, improve the quality and effectiveness of teaching it? I believe that classroom teaching should be
