高中化学繁多的概念和较强的逻辑性使大部分学生知识体系凌乱。概念图以结构化图解的方式,可以直观地表达出概念之间的相互关系,把相关的基本概念有机地联系起来。概念图是使化学知识条理化、系统化的有效工具。一、概念图的基本理论1.基本要素概念图包括结点、连线和连接词三部分。不同结点通过连线联系起来,上层概念可以引出不同的概念分支,各分支之间的连线就是交叉连接。连接词置于连线
The high chemistry concept and high logic of high school made most students’ messy knowledge system. Conceptual diagram structured structured approach, you can intuitively express the relationship between concepts, the basic concepts associated organically linked. Concept maps are effective tools for systematizing and systematizing chemical knowledge. First, the basic theory of conceptual map 1. The basic elements of the concept map, including nodes, connections and connectives in three parts. Different nodes are connected through the connection, the concept of the upper layer can lead to different concept branches, the connection between the branches is the cross-connection. Connectives placed on the connection
