众所周知,小学生升入初中后,特别是进入初中二年级后,数学成绩呈两极分化趋势:一些优秀生学习起来如鱼得水,而一些差生上数学课如做监牢。如何改变这一状况,让每个学生数学素质都得到全面均衡发展,最终实现“差生”转化、中等生优化、优生深化发展的目标?为此,我们通过 As we all know, after primary school students were admitted to junior high school, especially after they entered the second grade of junior high school, their mathematics results showed a polarization trend. Some outstanding students learned to get water, and some poor students took math classes as prisons. How to change this situation so that each student’s mathematics qualities will be fully and balancedly developed, and ultimately achieve the goal of “poor student” transformation, middle school student optimization, and eugenics development. For this purpose, we will
