设计合理的数学作业,能够让学生体验到成功,也有利于提高学生学习数学的兴趣,调动学生学习数学的积极性。设计过量的、重复的、不切实际的数学课外作业,既增加了学生的课业负担,又影响了学生的全面、健康发展。数学教师设计课外作业通常要具有下面四种作用:一是能够了解学生对刚刚学习的知识的掌握程度;二是能够为下一节新课作准备;三是能够帮助学生更好地理解所学知识之间的区别与联系;四是能够拓展学生的思维。 Well-designed math homework can enable students to experience success, but also help to improve students’ interest in learning math and arouse their enthusiasm for learning math. Excessive, repetitive and unrealistic math homework assignments not only increase students’ academic burden but also affect their overall and healthy development. Math teachers usually have the following four roles in homework assignments: one is to understand how well a student learns what they have just learned; the other is to be able to prepare for the next new class; and the third is to help students better understand what they have learned The difference between knowledge and contact; Fourth, to expand students’ thinking.
