化学概念把元素和化合物的知识、化学原理、化学计算、化学实验等有机结合起来,形成一个完整的知识体系,这是初中化学教材的特点。化学概念是整个化学基础知识的基础,离开化学概念,就无法进行化学教学。一、教师引导学生开展思维活动,抽出概念的本质属性,着重对概念的理解要使学生真正形成正确的概念,必须通过他们自己的
The chemical concept combines the knowledge of elements and compounds, chemical principles, chemical calculations, and chemical experiments to form a complete knowledge system. This is a feature of junior high school chemistry textbooks. The concept of chemistry is the basis of the entire chemical basic knowledge. Without the concept of chemistry, chemistry teaching cannot be carried out. First, the teacher guides students to carry out thinking activities, extracts the essential attributes of the concept, emphasizes understanding of the concept so that students can truly form the correct concepts, and must pass their own
