数学是一门研究现实世界空间形式和数量关系的学科,具有内容的抽象性、广泛的应用性和活动的可操作性,学生在自主探索和实践活动的基础上完成学习任务,因而需要通过小组协和、交流讨论,共同解决问题。《数学课程标准》指出:“有效的数学学习活动不能单纯地依赖模仿与记忆,动手操作、自主探索与合作交流是学生学习数学的重要方式。”合作学习是以小组为基本的组织形式, Mathematics is a discipline that studies the relationship between spatial form and quantity in the real world. It has content abstraction, wide application, and operability of activities. Students complete learning tasks on the basis of independent exploration and practical activities, and thus need to pass the group. Conciliation, exchanges and discussions to solve problems together. The “Mathematics Curriculum Standards” pointed out: “Effective mathematics learning activities cannot simply rely on imitation and memory. Hands-on operation, independent exploration and cooperation and communication are important ways for students to learn mathematics.” Cooperative learning is based on the group’s basic organizational form. ,
