迁移就是利用已经掌握的知识和技能,促进掌握新的知识和技能。由于数学学科具有高度的抽象性和严密的逻辑性,而小学生的抽象思维能力较差,往往不能沟通新旧知识、技能之间的联系。因此教师应精心安排教学内容,揭示知识的内在联系,促进知识的迁移。一抓好基础,促进迁移。迁移的产生是有条件、有规律的。一般地说,学生掌握的基础知识越多、越牢固,就越容易实现迁移,顺利地掌握新知识。例 Migration is the use of already-acquired knowledge and skills to promote mastery of new knowledge and skills. Due to the high degree of abstraction and strict logic of mathematics, pupils are often unable to communicate the old knowledge and skills because of their poor ability of abstract thinking. Therefore, teachers should carefully arrange the teaching content, reveal the intrinsic connection of knowledge and promote the transfer of knowledge. Grasp the foundation and promote migration. Migration is conditional and regular. Generally speaking, the more basic knowledge a student has, the firmer the solid foundation is, the easier it is to migrate and acquire new knowledge smoothly. example
