笔者从事一线教学工作已有二十多年,先后担任初中语文、小学数学等教学工作。但不论哪科哪级教学,班上都不同程度存在着两极分化的现象。特别是在数学学习过程中表现得明显:优秀学生学得越来越好,而成绩差的学生越来越差;好的学生越学越想学,而后进生越学越感到厌烦,有的甚至想放弃数学的学 I have been engaged in first-line teaching for more than 20 years, has served as junior high school language, primary school mathematics and other teaching work. But no matter what level of teaching, there are different degrees of polarization in the class. Especially in the process of mathematics learning is obvious: excellent students get better and better, and poor students are getting worse and worse; good students learn more and more want to learn, and then into the learning more boring, and some Even want to give up mathematics learning
