在初中化学教材中,基本概念几乎每节都有,而化学概念是学习化学必须掌握的基础知识,准确地理解概念对于学好化学是十分重要的。初中学生的阅读和理解能力都比较差,因此,教师在教学过程中讲清概念,把好这一关是非常重要和必要的。化学概念是用简练的语言高度概括出来的,常包括定义、原理、应用规律等。其中每一个字、词、每一句话、每一个注释都经过
In junior high school chemistry textbooks, the basic concepts are almost every section, and the chemical concept is to learn the basic knowledge that chemistry must grasp.
