《数学课程标准》提出,“要让学生在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,就是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。让学生亲历经验,不但有助于通过多种活动探究和获取数学知识,更重要的是学生在体验中能够逐步掌握数学学习的一般规律和方法。自主探究——让学生体验“再创造”有位数学家说过,“学习数学的唯一正确方法是实行再创造,也就是由学生把 The Mathematics Curriculum Standard states: ”Let students acquire some experience when participating in specific mathematical activities and initially recognizing the characteristics of objects in specific situations.“ The so-called experience is that an individual personally or personally experiences something Obtain direct experience of the corresponding cognitive and emotional activity. Let students experience, not only help through a variety of activities to explore and acquire mathematical knowledge, more importantly, students can gradually grasp the general rules and methods of learning mathematics. Self-exploration - let students experience ”re-create “ There is a mathematician said, ”The only correct way to learn math is to recreate, that is, by the students
