初中阶段学生数学学习成绩两极分化呈现出比小学阶段更严重的趋势,后进生所占的比例较大,特别在初中二年级表现得尤为明显;这种状况直接影响着大面积提高数学教学质量。那么,造成两极分化比较严重的原因是什么?如何预防严重分化?本文结合自己的教学实践作一些粗浅的探讨。 The polarization of junior high school students’ mathematics achievement shows a more serious trend than that of primary school, and the proportion of backward students is relatively large, especially in the second grade of junior middle school. This situation directly affects the quality of mathematics teaching in a large area. What are the causes of the more severe polarization? How to prevent serious differentiation? This article combines some of the shallowest explorations of teaching practice.
