概念是准确描述事物的载体和工具。而化学概念是用简练的语言对化学现象进行的高度概括,它主要涵盖一些常见的定义、原理、反应规律等。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。由于概念本身的属性和各种条件的限制,不可能所有概念用同一教法。
Concepts are vehicles and tools that accurately describe things. The chemical concept is a concise language to summarize the chemical phenomenon, which mainly covers some common definitions, principles, reaction rules and so on. 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. Due to the nature of the concept itself and the limitations of various conditions, it is not possible to use the same teachings for all concepts.
