数学作为衡量一个人能力的重要学科,从小学到初中绝大多数学生对它情有独钟,投入了大量的时间与精力,然而并非人人都是成功者。许多小学数学学科成绩的佼佼者,进入初中阶段,第一个跟头就栽在数学上。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？本文结合我自己的教学实践作一些粗浅的探讨。
Mathematics as an important discipline to measure a person’s ability, most students from elementary school to junior high school devoted a lot of time and energy to it, however, not everyone is a winner. Many outstanding primary school mathematics disciplines, into the junior high school stage, the first sub-planted in mathematics. The polarization of math achievement in junior middle school shows a more serious trend than that in primary school, and the proportion of postgraduates accounts for a large proportion, especially in the second grade of junior high school. This situation directly affects a large area to improve the quality of mathematics teaching. So what is the cause of the more serious polarization? How to prevent severe differentiation? This article combines my own teaching practice to make some superficial discussion.
