初中数学的分层教学能让教师的教和学生的学相互促进,能避免平行分班和班级授课模式的弊端,关注学生的个体差异,促进每个学生在原有基础上得到最大限度的发展。笔者在《等腰三角形复习》中先仔细分析本班学生的学习情况,然后有针对性的组织复习,取得了良好的效果。一、通过“知识回忆”激发各层次学生的学习积极性在回忆这个环节,笔者设计为两部分,一是热身练习,二是知识点梳理。想通过热身练习使每个学生的思维都紧紧围 The junior middle school math teaching can make the teaching of teachers and students learn each other to promote, avoid the disadvantages of parallel class and class teaching mode, pay attention to the individual differences of students and promote the maximum development of each student based on the original. In the “isosceles triangle review”, I carefully analyze the learning situation of students in this class, and then targeted the organization review, and achieved good results. First, through the “memory of knowledge ” to stimulate the enthusiasm of students at all levels in the memory of this part, I designed for two parts, one warm-up exercise, and second, knowledge points comb.
