中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,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,造成两极分化的原因是什么?如何预防呢?我将结合自己几年来教学实践作一点粗浅的探讨。 The polarization of middle school students’ mathematics achievement shows a more serious trend than that of the primary school, especially in the second grade of junior high school. This situation directly affects a large area to improve the quality of mathematics teaching. Then, what are the causes of polarization and how can we prevent it? I will use my own teaching practice over the past few years to make a brief discussion.
