传统的作业训练方式,多是教师机械地指定一些课后习题,或是设计一些课外知识习题,让学生统一练习。其实质是以一把尺子评价一切,以一个标准衡量一切。这样做,显然不能满足全体学生的学习要求,容易使“尖子生吃不饱”“学困生吃不了”“教师吃力不讨好”;容易挫伤学生的学习积极 Traditional methods of homework training are mostly teachers mechanically assigning some after-school exercises or designing extra-curricular knowledge exercises so that students can practice in a unified way. Its essence is to evaluate everything with a ruler, measure everything with a standard. In doing so, it obviously can not meet the learning requirements of all students, making it difficult for students to learn enough to eat.
