一、细分小组,充分发挥小组合作学习的作用我把班级中的学生按照3人一组分成若干个小组,每个小组有一个组长和两个组员,组长是相对成绩好的学生,每三个组长又有另一个同学是他们的组长,这样依次安排,课代表是最大的一个组长。我安排的特点是组员人数少,一个组长带动两个组员,这样小组间的3个学生更好交流。根据数学内容和学生的实际情况,选择恰当的时机进行小组教学,充分发挥小组学 First, the sub-groups, give full play to the role of group cooperative learning I class in accordance with the students in a group divided into several groups, each group has a leader and two team members, the leader is relatively good students , And every third leader has another classmate is their leader, so arranged in turn, class representatives is the largest one leader. My arrangement is characterized by a small number of members, a leader led two members, so that the three groups of students better communication. According to the mathematical content and the actual situation of students, choose the right time for group teaching, give full play to group science
