一、案例背景小学数学作业是帮助学生认识数学概念的形成、掌握数学知识、运用数学方法与技能的一种十分重要的手段,因此作业是学生学习中一项最基本、也是一个必不可少的数学学习活动。长期以来,大部分教师布置的作业都是以计算题和应用题形式的练习题为主,这样,学生作业的形式就比较单一和传统,而且每个学生都在重复地练习着,因此学生仍停留在以“做”为主的机械操作式的作业模式中,没有做到按学生的需求来分层次布置多样化的作业,让更多的学生得到 First, the case background Primary school math homework is to help students understand the formation of mathematical concepts, master mathematical knowledge, the use of mathematical methods and skills of a very important means, so homework is one of the most basic student learning, but also an essential Mathematics learning activities. For a long time, most of the homework assignments by teachers are mainly based on the exercises of calculation questions and applied questions, so that the students’ assignments are simple and traditional, and each student is practicing repeatedly. Therefore, Stay in the “done ” based mechanical operating mode of operation, did not do according to the needs of students to lay out a wide range of homework assignments, so that more students get
