化学概念能深刻地反映化学过程中的最本质的特征,是人们思维的结晶,也是课程内容的重要组成部分,是化学知识的“骨架”.化学概念还是学生进行化学思维的依据和出发点,是学习化学基本理论、元素化合物及其它知识的基础.如何让化学概念教学更加有效,笔者通过实践提出了以直观为基础引入概念、以合作为把手辨析概念、以应用为辅助巩固概念等三点措施.这样的教学方法在教学实践中也取得了优良的效果.
The concept of chemistry can profoundly reflect the most essential features of chemistry, is the crystallization of people's thinking, is also an important part of the course content, and is the “skeleton” of chemical knowledge. The concept of chemistry is also the basis and starting point for students to conduct chemical thinking , Is to learn the basic theory of chemistry, chemical compounds and other elements of the foundation.How to make the teaching of chemical concepts more effective, the author put forward through the practice of intuition as the basis for the introduction of the concept of cooperation as a handle to identify the concept of application to help consolidate the concept of three This measure of teaching has also yielded excellent results in teaching practice.
