概念是事物的本质属性在人脑中的反映。化学基本概念则是对化学现象一般的、本质的反映。在教学中使学生形成正确的化学概念,能使学生对化学所研究的物质及其变化的认识不致停留在低级的感性阶段,能使他们更完全地更深刻地认识化学所研究的具体物质及其变化规律。对化学基本概念的理解,不仅是学生学好基础理论、定律、公式的前提和基础,也是发展学生智力,特别是逻辑思维能力的必要条件。同时概念教学和其他理论知识的教学有类似的规律,分析研究概念的形成过程,也有利于搞好整个基础知识的教学。
The concept is the reflection of the essential attributes of things in the human brain. The basic concepts of chemistry are the general and essential reflection of chemical phenomena. In teaching students to form the correct chemical concepts, enabling students to study the chemical substances and their changes do not stay in the low level of emotional phase, enabling them to more fully understand the chemistry of the specific material and The law of change. The understanding of the basic concepts of chemistry is not only the precondition and foundation for students to learn basic theories, laws and formulas, but also the necessary condition for developing students’ intelligence, especially logical thinking ability. At the same time, concept teaching and other theoretical knowledge teaching have similar rules, analyzing the formation of research concepts, but also conducive to do a good job teaching the entire basic knowledge.
