《全日制义务教育数学课程标准》指出:有效的数学学习活动不能单纯地依赖模仿与记忆,动手实践、自主探索与合作交流是学生学习数学的重要方式。然而,小学生受原有知识经验和能力的限制,不可能在短期内完全独立地完成探索任务。因此,必须依靠教师的组织和指导进行自主探索活动。
Full-time compulsory education mathematics curriculum standards pointed out: Effective mathematics learning activities can not simply rely on imitation and memory, hands-on practice, independent exploration and cooperation and exchange is an important way for students to learn mathematics. However, primary school students can not complete the task of exploration completely and independently within a short period of time due to their limited prior knowledge and ability. Therefore, we must rely on the organization and guidance of teachers to conduct their own exploration activities.
