化学概念在化学知识体系中的地位是不言而喻的 ,它充当着知识网络中的“节点” .掌握化学概念 ,有助于化学知识的系统化 .在认知结构中若难于形成清晰的化学概念 ,则谈不上真正掌握化学变化的内在联系及其规律 .在复习化学概念时 ,我们应该重视的一项工作是界定概念的关键特征
The status of a chemical concept in a chemical knowledge system is self-evident. It serves as a “node” in a knowledge network. Grasping a chemical concept helps to systematize chemical knowledge. If it is difficult to form a clear structure in a cognitive structure The chemical concept is not really to grasp the internal connection and laws of chemical change.
