迁移是一种心理现象,是先行学习对今后学习所产生的影响,起积极作用的叫做正迁移,起消极作用的叫做负迁移。我们先来谈谈正迁移。数学中大量应用的联想、类比、转化等都是正迁移,如讲同底数幂相除,将除数转化成负指数就与同底数幂乘法类同,从而达到正迁移的良好效果,再如在讲二 Migration is a psychological phenomenon. It is the influence of learning in advance on the learning of the future. The positive effect is called positive migration. The negative effect is called negative migration. Let’s talk about moving now. Many associations in mathematics such as association, analogy, transformation, etc. are positive transitions. If divided by the base number power, the divisor is converted into a negative exponent and is similar to the same base power multiplication, so as to achieve a positive effect of positive migration. two
