作业是一项非常重要的学习活动,完成的优异与否关系着所做这件事情能否成功。作为一线数学老师,我们必须重视数学作业的布置,提高作业的有效性,从而促进学生数学的学习。一、尊重差异,布置作业必须体现出层次性数学知识,必须经过准备复习(新旧知识联系)、新授(师生共同探究)、巩固(学生作业)几个环节来完成。从这个角度看学生应该有作业,但我们布置作业要有层次性,决不可从头到尾一刀切,做机械重复性作业。其实,不管从教材上看,还是从众多的试卷上观察,都能明显地看到诸如“A级、B级、C级”“基础练习”“提高作业”“综合应用”等分层次的设计,这当然是很可取的,但关键还是教师以及 Homework is a very important learning activity, the completion of the excellent or not depends on the success of this matter. As a first-line math teacher, we must attach importance to the layout of math homework to improve the effectiveness of homework, thus promoting students’ math learning. First, respect for differences, assignments must reflect the level of mathematical knowledge must be prepared to review (old and new knowledge links), the new grant (teachers and students to explore), consolidate (student assignments) to complete several links. From this point of view, students should have homework, but we have to assign homework to different levels. We must never make a one-size-fits-all mechanical work repetitively. In fact, no matter from the teaching materials, or from many papers on the observation, can clearly see such as “A, B, C ” “basic practice ” Of course, it is desirable to apply a hierarchical design, but the key is that teachers and
