现代社会与科技发展日新月异,没有自主学习能力的人,是无法在社会竞争中生存下来的。《小学数学新课程标准》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。”由此可见,传统的依赖教师讲解的学习方式已经不适应新课改的发展,终将会被社会淘汰。再加上数学学科的逻辑思维性很强,单靠教师的讲解是无法帮助小学生真正获得数学知识与技能的,因此,转变被动的学习 With the rapid development of modern society and science and technology, those without self-learning ability can not survive in social competition. The New Curriculum Standard for Elementary School Mathematics states: “Effective mathematics learning activities can not rely solely on imitation and memory. Hands-on practice, independent exploration and cooperation and exchange are important ways for students to learn mathematics.” Thus, the traditional teacher-dependent Explained learning methods have not adapted to the new curriculum development, will eventually be social out. Coupled with the strong logical thinking of mathematical subjects, teachers alone can not help the pupils really have access to mathematical knowledge and skills, therefore, change the passive learning
