1 问题的提出当前初中数学教学中常有这样的现象 :不少聪明的学生 (尤其是男生 )往往较“粗心” ,学习成绩波动性大 ;而多数智力平平者学习成绩却稳定 ,甚至较好 ;初二学生的数学学习较易产生两极分化 ;民办初中学生数学学习成绩明显优于公办初中学生 .为什么会产生上述现象 ?
1 Problems The current phenomenon of junior middle school mathematics teaching often has this phenomenon: Many savvy students (especially boys) tend to be more “careless” and have greater volatility in academic performance; while most of the students of the same class have stable or even better academic performance; The second grade students’ mathematics learning is more prone to polarization; the junior high school students’ mathematics learning performance is obviously better than the public junior high school students. Why does the above phenomenon occur?
