新课标提出:“要让学生参与特定的数学活动,在具体情境中初步认识对象的特征,获得一些体验。”所谓体验即个体主动亲历或虚拟地亲历某件事并获得相应的认知和情感的直接经验的活动。借助学生已有的经验,通过多种活动探究可以有利于学生主动获取、掌握运用数学知识,更有利于学生在体验中逐步提升自己数学学习的能力、方法。但时下有许多数学教学中有 The new curriculum proposed: “To enable students to participate in specific mathematical activities, in the specific context of the initial understanding of the characteristics of the object, to obtain some experience.” The so-called experience that the individual personally experienced or virtual to experience something and get the corresponding recognition Direct experience of knowing and feeling of activity. With the help of the students ’experiences, exploring through multiple activities can help students take the initiative to acquire and master the knowledge and skills of mathematics, which is more conducive to students’ ability to gradually improve their math learning experience. But there are many mathematical teaching nowadays
