“作业是一种有目的、有指导、有组织的学习活动,它是教学的基本环节,有助于所学知识的巩固与深化,有益于技能、智力和创造力的发展,是提高学生素质的重要载体。”针对传统数学作业存在的问题,如小学数学作业的形式单调、内容重复、要求统一、评价单薄,缺乏作业的实效性和思维性,不利于学生数学素养的全面提高。通过几年的实践与研究,发现应通过优化数学作业来减轻学业负担:作业要求层次性,让学生能做;作业形式多样性,让学生想做;作业评价多元性,让学生乐做。 “Homework is a purposeful, guided and organized learning activity. It is an essential part of teaching. It helps to consolidate and deepen what is learned, and is beneficial to the development of skills, intelligence and creativity, Quality of the important carrier. ”For the problems of traditional math homework, such as the monotonous form of primary school math homework, repetitive content, unity, evaluation of thin, lack of effectiveness and thinking of homework, is not conducive to the overall improvement of students’ mathematical quality. After several years of practice and research, I found that the academic burden should be reduced by optimizing math homework: job requirements should be hierarchical and students should be able to do it; job forms should be diversified so that students would like to do it;
