有这样一句话:初一差距不大,初二两极分化,初三天上地下。是说到了初三,特别是数学,学生两极分化严重,差距越来越大,原因是多方面的,从小学到初中,知识之间的联系非常密切,一旦基础知识打不扎实,知识链就会出现断层,题目中一遇到断层的知识点,或知识间联系不起来,题目就不可能解决,久而久之,成绩差,学生对学习数学就会不感兴趣,所以学生学习数学要想有持之以恒的耐心,遇到困难不灰心。
There is such a sentence: a small gap between the first two poles polarization, the first three days on the ground. When it comes to the third year, especially mathematics, students’ polarization is serious and the gap is widening. There are many reasons for this. There are many reasons for this. From primary school to junior high school, the connection between knowledge is very close. Once the basic knowledge is not played well, There will be a fault, the subject of a knowledge of the fault encountered, or knowledge can not be linked, the problem can not be solved, over time, poor grades, students will not be interested in learning mathematics, so students want to learn mathematics perseverance Patience, not discouraged in the face of difficulties.
