从知识掌握的规律来看,学生对数学的学习主要集中在方法的掌握和计算规律的理解上,不科学的作业设计不仅不能达到应有的效果,反而会消耗学生的学习耐心和热情,降低学生对知识的敏感度,影响知识理解的准确性。本文指出了大题量、作业系统性差、作业一刀切三个误区,并提出了相应的对策,力图为小学数学作业设计提出一些有益的见解。 Judging from the law of knowledge, the students mainly focus on the mastery of methods and the understanding of the laws of calculation. The unscientific homework design can not only achieve the desired results, but also consume students’ learning patience and enthusiasm and reduce Students’ sensitivity to knowledge affects the accuracy of knowledge comprehension. This paper points out three major errors, such as large quantity, poor operating system and homework, and puts forward corresponding countermeasures in an attempt to put forward some useful ideas for the design of primary school mathematics.
