十年课改,百花齐放,让我们每一位教师都深切地感受到课改带给学校、教师、学生的巨大变化,我们欣喜地体会到课改为小学数学教学注入的新活力,带来的新教育理念和教育方式.但也不得不承认,“两极分化”的现象也正随着知识的拓宽而悄然蔓延着,后进生所占比例逐年增大,小学中年级正是两极分化的开端,到了高年级表现得尤为明显.因此在小学阶段,我们教师就应重视起两极分化的现象,找到原因,以有效的策略遏止两极分化.下面,笔者就小学数学教学中出现的两极分 Ten years of curriculum reform, let flowers bloom, so that every one of our teachers are deeply felt the great changes brought by the curriculum reform to schools, teachers, students, we are pleased to appreciate the curriculum reform into primary school mathematics teaching into the new vitality brought But also have to admit that the phenomenon of “polarization” is also quietly spreading with the widening of knowledge. The proportion of post-graduates increases year by year, and the middle school of primary school is polarized Therefore, in the elementary school, our teachers should attach great importance to the phenomenon of polarization, find the reason and stop the polarization with effective strategies.In the following, the author analyzes the two poles that appear in the elementary mathematics teaching
