一、案例背景《数学课程标准》中指出:“有效的数学学习活动不能单纯的依赖模仿和记忆,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。”因此,数学的学习活动应该是学生探究、合作、体验的过程。经过主动探究,才能有所发现、有所创新;经过体验、合作,才能集思广益、有所提升。 First, the background of the case “Mathematical Curriculum Standard” states: “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.” Therefore, the study of mathematics Activities should be students explore, cooperation, experience the process. Through active exploration, we can find something and innovate. Only through experience and cooperation can we draw on collective wisdom and improve ourselves.
