自从事高中数学教学工作以来,我发现高一学生的数学成绩有一个怪现象,中考一百三四十分的学生,高一阶段的前两三次考试却有30%～40%的不及格,这种现象值得深思。高一数学教材相对初中数学教材有一个落差很大的台阶,知识内容和整体数量较初中剧增,知识结构发生了很大的变化。就高一教材而言,概念、定理、符号就有近百个,这么多东西要全部
Since I was engaged in high school mathematics teaching, I have found that there is a strange phenomenon in the mathematics performance of Grade One students. In the 1403 students in the examination, 30% to 40% failed in the first two or three times in the first grade. This phenomenon is worth pondering. High school mathematics textbooks have a big gap with respect to junior high school mathematics textbooks. The knowledge content and overall quantity have increased dramatically compared with junior high schools, and the knowledge structure has undergone great changes. In the first grade textbook, there are nearly a hundred concepts, theorems, and symbols. So many things need to be all
