化学基本概念是整个中学化学知识的基础,加强基本概念教学,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,能使学生更深刻地认识化学所研究的物质及其变化规律。掌握好化学概念是学生学好基础理论、定律、公式的前提,也是发展学生智力,特别是逻辑思维能力的必要条件。因此,基本概念在教学中占有十分重要的地位。
The basic concept of chemistry is the basis of chemistry knowledge of the whole secondary school. Strengthening the teaching of basic concepts enables students to recognize that the studied substances and their changes in chemistry do not stop in the low-level perceptual stage and enable students to have a deeper understanding of the substances studied by chemistry And its variation. Grasping the concept of chemistry is a prerequisite for students to learn basic theories, laws and formulas. It is also a necessary condition for developing students’ intelligence, especially logical thinking ability. Therefore, the basic concepts occupy a very important position in teaching.
