合作学习中学习小组的建立改变了在传统课堂教学中师生单向交流,教师垄断整体课堂的信息源而学生处于被动地位,学生的主动性、创造性也因此得以充分的发挥。如果将数学作业的批改引人到学习小组活动中,既可以丰富小组学习的内容,将小组的合作、互动探究从课堂延续到课外,又能借助小组合作学习的力量提高数学作业的质量,优化作业的批改方式。 The establishment of learning groups in cooperative learning has changed the one-way communication between teachers and students in the traditional classroom teaching.
