“双减”政策下做好数学作业“加减法”探研

Research on the"Addition and Subtraction Method"of Doing Math Work Well under the"Double Reduction"Policy

作业是课堂教学的补充和延伸,既能让学生巩固课堂所学内容,也能让教师及时发现学生薄弱点,及时调整接下来的教学方向,提高教学的针对性。“双减”政策下,教师都在积极探索数学作业优化方案,但往往存在一个误区,即作业优化就是减少作业数量,压缩作业完成时间。其实不然,作业改革需要做好“加减法”,一方面,要通过合理削减机械性、重复性的题型,压缩课后作业时间。另一方面,要通过丰富作业类型、分层设计作业等方式,提高作业质量,更好地发挥作业应有的作用。

Homework is the supplement and extension of classroom teaching,which can not only help students consolidate what they have learned in class,but also enable teachers to find out students'weaknesses in time,adjust the following teaching direction in time,and improve the pertinence of teaching.Under the"double reduction"policy,teachers are actively exploring the optimization scheme of mathematical homework,but there is often a misunderstanding that homework optimization is to reduce the number of homework and shorten the completion time of homework.In fact,homework reform needs to do a good job of"addition and subtraction method".On the one hand,we should reduce the homework time after class by reasonably reducing mechanical and repetitive questions.On the other hand,it is necessary to improve the quality of work and play its due role better by enriching the types of work and designing work hierarchically.
