许多学生一进入中学,随着学习科目的增多,就明显感觉到数学“难学”。加上有的教师在作业布置上不仅没有分层要求,而且还随意拔高,补充一些难题,学生如果做不出来,老师还在课堂上流露出不满,所以导致学生对学好数学的信心不足,兴趣降低。长期下去,会使学生成绩出现过早的分化,使面向全体学生的教学思想成为一句空谈。小组 As soon as many students enter secondary school, they clearly feel math “difficult to learn” as their study subjects increase. In addition, some teachers not only do not have any delamination requirements in job placement, but also arbitrarily set high and supplement some problems. If the students can not do it, the teachers are still dissatisfied with the class. As a result, students' lack of confidence in learning mathematics and their interest decrease . In the long run, students' scores will be prematurely differentiated, making the teaching ideology for all students become an empty talk. group
