优化小学数学课堂教学结构,提高数学课堂教学效率,减轻学生过重的作业负担的一个重要方面就是优化课堂练习设计,研究课堂练习形式,讲求课堂练习设计艺术,即"练习的内容要紧扣教学要求,目的明确,有针对性。练习题的数量要适当,能适应不同程度的学生需要,练习设计要有坡度、有层次,难易适度,适应儿童的特点。 An important aspect of optimizing classroom teaching structure in primary schools, improving teaching efficiency in math classrooms and alleviating students’ heavy workload is to optimize classroom practice design, study the form of classroom practice, and emphasize the practice of classroom practice, that is, the content of exercises should be closely linked Teaching requirements, purpose clear, targeted. The number of exercises to be appropriate to adapt to different levels of student needs, practice design should have gradient, level, easy to moderate, to adapt to the characteristics of children.
