类比是一种重要的思维方式。伟大的科学家牛顿就这样认为:“没有大胆的类比,就做不出伟大的发现”。化学上的许多创造就是以此为前提的。可见,类比是以科学发现为先导的,其重要性是不言而喻的。那么,在化学学习中应如何指导学生掌握化学类比的有关策略,做出合乎科学规律的类比呢?一、引导学生从已有的知识进行迁移类比建构主义认为:“知识和意义不是简单由外部信息决定的,意义是学习者通过新旧知识经验间反复的、双向的相互
Analogy is an important way of thinking. The great scientist Newton thought: ”Without a bold analogy, we can not make a great discovery.“ Many chemical creation is based on this as a prerequisite. Obviously, analogy is based on scientific discovery, its importance is self-evident. So, how to guide students in chemistry learning to master the chemical analogy strategy, to make scientific analogy? First, to guide students to migrate from existing knowledge Analogy Constructivism that: ”knowledge and meaning is not simple The external information determines the significance of the learner through the experience of old and new knowledge of repeated, two-way mutual
