如何将抽象的、理性的化学知识感性化、生活化、趣味化,使知识浅显易懂,降低学生的学习难度,激活学生的思维,化枯燥的理科学习为快乐地学习,是教师必须不断探索的课题。本文主要是对离子键、共价键的电子式的书写做个“型”似比拟,借助学生日常生活中熟悉的情境,将抽象的化学知识生活化,使教与学都达事半功倍之效,同时帮助学生掌握举一反三的类比学习方法。
How to sensitize the abstract and rational chemical knowledge, to make life more interesting, to make the knowledge easy to understand, to reduce the students ’learning difficulty, to activate the students’ thinking, to turn the boring science study into a happily learning is that teachers must constantly explore The subject. This paper mainly compares the electronic writing of ionic bonds and covalent bonds with analogy. With the students’ familiar situations in their daily life, it will abstract the chemical knowledge to make life more effective and make both teaching and learning more effective. Effect, at the same time help students master the analogy learning from one method and the other.
