为了培养新世纪的人才,小学数学课堂就应当成为教师、学生之间交流数学思想的场所。把教师讲学生听的一言堂变成学生自主学习交流合作的群言堂。而合作学习正是在教师的正确引导下,学生以小组为单位,根据合作学习的目标,进行讨论,发表意见,相互交流、学习,完善自己对数学问题的认识和理解。从而使学生的个性才能在交流与合作中得到激发,并且取长补短,集思广义,学会合作,最终得到学习的成功。一、合理分工 In order to train talents in the new century, the elementary mathematics classroom should be the place where teachers and students exchange mathematical ideas. The teacher speaks the students to listen to the words into a group of students to learn the exchange of cooperation. Cooperative learning is precisely under the guidance of teachers, students in groups as a unit, in accordance with the objectives of cooperative learning, discussion, comment, mutual exchange, learning, improve their knowledge and understanding of mathematical problems. So that the personality of students can be stimulated in the exchange and cooperation, and learn from each other, brainstorming broad, learn to cooperate, and ultimately get the success of learning. First, a reasonable division of labor
