人类的学习不可能脱离过去的经验,这是一个不言而喻的事实。每当学习者面临新的学习任务,都可能会有意或无意地与以前所学的知识和技能相联系,而后继的学习也不可避免地对以前的学习结果给予某些影响。因此心理学提出迁移这一概念,并将其定义为“一种学习对另一种学习的影响”。当这种影响对学习起促进作用时,称为正迁移;反之,则称为负迁移,或称进入迁移波谷区。本文就化学教学中出现的负迁移现象及防止此现象的发生谈一些看法。一、化学教学中的负迁移现象 It is an obvious fact that human learning can not be divorced from past experience. Whenever learners face new learning tasks, they may be consciously or unconsciously associated with previously learned knowledge and skills, and subsequent learning will inevitably have some impact on previous learning outcomes. Therefore, psychology puts forward the concept of migration and defines it as “the influence of learning on another kind of learning.” When this effect on learning to play a role in promoting, known as positive migration; the other hand, known as negative migration, or into the migration trough area. This article talks about some negative migration phenomena in chemistry teaching and how to prevent this phenomenon from occurring. First, the negative shift in chemistry teaching
