一、教师必须转变角色在合作学习中,教师的角色该如何定位?《数学课程标准》明确指出,教师是数学学习的组织者、引导者和合作者。但是在实际教学中,教师往往不能把握自己的角色。在学生讨论时,教师要么站在讲台前,要么轮流转几圈,看看这组,瞧瞧那组,不能把自己融入到学生的学习中,也就不可能成为学生的学习合作伙伴。归根到底还是教师的角色没有发生转变。因此教师要在学生的合作学习中能发挥更好的 First, the teacher must change the role of cooperative learning, the role of teachers how to position? “Mathematical Curriculum Standards” clearly pointed out that teachers are the organizers of mathematics learning, guidance and collaborators. However, in actual teaching, teachers often can not grasp their own role. When students discuss, teachers either stand in front of the podium, or turn around a few laps, take a look at this group, look at the group, can not integrate themselves into student learning, it is impossible to become a student learning partner.
