迁移,是已有知识在新情境中的应用。在人们认识过程中客观存在的迁移,有正迁移和负迁移。在数学教学过程中驾驭迁移规律,就是要努力促成正迁移的实现,同时注意克服负迁移的干扰和影响。一、以基本概念为中心组织教学内容心理学的研究说明:已有知识的概括水平越高,实现迁移的可能性越大。在小学分数乘除法应用题教学中,我作过这样的尝试:以分数乘、除法运算的意义和“比较”、“对应”思想为中心组织教材,分两个阶段进行训练。第一阶段重点指导学生理解分数乘除法的意义。掌握“整体1”、“几分之几”和“几分之几所
Migration is the application of existing knowledge in new situations. In the course of people's understanding of objective migration, there are positive and negative migration. In the process of mathematics teaching to control the transfer of the law, is to strive to promote the realization of positive migration, while paying attention to overcome the negative transfer of interference and influence. First, the basic concepts of the organization of teaching content Psychology research shows that: the higher the level of generalization of existing knowledge, the greater the possibility of migration.

The first phase focuses on guiding students to understand the meaning of multiplication and division of scores. Master the “overall 1”, “a few” and "a few
