有效作业设计是数学教学改革的一个重要内容。教师要融数学作业以层次性,针对性,多样性,趣味性,实践性,合作性,在设计作业的题目方面,从“有效”入手,设计缜密,有的放矢,关注细节,深度反思,做到了选题精。通过基础知识的梳理、巩固、纠错、重组、变式、拓展、探究等活动,层层深入突出重点,探究活动主动构建,真正引导学生经历“做数学”的过程,实现真正意义上的“减负提质”。 Effective job design is an important part of mathematics teaching reform. Teachers should integrate mathematics homework into a series of topics such as hierarchy, pertinence, diversity, fun, practicality and cooperation. In terms of designing homework, teachers should start with “Effective ”, be careful about the design, Achieved the title of fine. Through the basic knowledge of combing, consolidation, error correction, reorganization, variation, expansion, exploration and other activities, layers of emphasis in depth, to explore active construction, and truly guide students to experience “doing mathematics ” process to achieve the true sense “Subconditions ”.
