由于学生个体差异、初中教材内容的加深、教学要求的逐渐提高、学习方法的改变、外界因素的干扰等多方面的原因,学生两极分化的现象特别严重,在数学方面尤为突出。优等生在不断减少,学困生队伍在不断扩大。如果教师不采取积极有效的策略,必然会使学困生越来越多。学困生,就是学习有困难的学生。具体表现为:学习基础差,上课不积极探讨问题,精力不集中、反应迟钝,对学习漠不关心、作业的完成靠东拼西凑或抄袭,考试成绩不理
Due to the individual differences of students, the deepening of the content of junior high school teaching materials, the gradual increase of teaching requirements, the change of learning methods, the interference of external factors and many other reasons, the phenomenon of polarization of students is particularly serious, especially in mathematics. The top students are declining, and the students who are studying hard are constantly expanding. If teachers do not take a positive and effective strategy, they will inevitably make learning more and more students. Poor students, is learning difficult students. Specific performance is: poor learning, class does not actively explore the problem, lack of concentration, unresponsive, indifferent to learning, homework done by patchwork or plagiarism, test scores ignore
