一、模型展示导入法化学模型可以变抽象为直观,因此抽象的知识点配以模型讲解更容易让学生感兴趣,也更容易让学生理解。如讲“原子晶体的结构和性质”时,可以向学生展示金刚石的结构模型,同时向学生解说:这是天然存在的最硬的物质———金刚石的结构模型,你想知道在什么情况下才能感觉到金刚石的温柔吗?要感觉到钻石的温柔必须付出怎样的代价吗?那么就让我们一起来学习原子晶体的结构和性质
First, the model shows the import method Chemical model can change the abstract is intuitive, so abstract knowledge points with the model to explain more easily to students interested in, but also easier for students to understand. When talking about “the structure and properties of atomic crystals,” you can show students the structural model of diamond while explaining to students that this is the hardest substance that exists naturally - the structural model of diamond, and you wonder what Can you feel the diamond’s gentleness? How much does it cost to feel the tenderness of diamonds? Let’s learn the structure and properties of atomic crystals
