美国著名心理学家杰罗姆·S·布鲁纳有一句名言:“获得的知识,如果没有完整的结构把它联系在一起,那是一种多半会忘记的知识”.即对知识的掌握贵在梳理.而“氧”知识是迈入化学殿堂的开篇章,是系统研究具体物质的开始.俗话说得好:“良好的开端,等于成功了一半”,梳理好“氧”知识,对后续化学学习富有启迪作用.梳理的方法主要有以下几种: The famous American psychologist Jerome S. Bruner has a famous saying: “The acquired knowledge, if it is not linked by a complete structure, is a knowledge that most of us will forget.” That is the mastery of knowledge. You are combing. The “oxygen” knowledge is the opening chapter into the chemical palace, and it is the beginning of the systematic study of specific substances. As the saying goes, “a good beginning is equal to half the success”, combing out the knowledge of “oxygen”. Follow-up chemistry learning is full of enlightenment. There are mainly the following combing methods:
