《义务教育化学课程标准(2011年版)》将初中化学概念教学目标定位于“形成一些最基本的化学概念,重视以化学基本观念为线索,将化学基本概念渗透在实际生活中”。依据这一总体原则,人教版初中化学教科书对于某些重要化学概念的表述进行了区别化处理,其中相当一部分概念采取的是一种“过渡性”认知处理办法,对于这些“过渡性”概念的正确认识与灵活有效把握是顺利实现初中化学课程目标的重要环节。一、初中化学“过渡性”概念的界定所谓初中化学“过渡性”概念(或称“阶段性”概
“Compulsory Education Chemistry Curriculum Standard (2011 Edition)” will be located in junior high school chemistry concept teaching goal “to form some of the most basic chemical concepts, attach importance to the basic concepts of chemistry as a clue, the basic concept of chemical infiltration in real life ”. According to this general principle, the PEP Junior Chemistry Textbook differentiates the expressions of some important chemical concepts. A considerable part of the concepts adopt a “transitional” cognitive approach. For these “ The correct understanding of the concept of ”transitional“ and the flexible and effective grasp are the important links to successfully achieve the objectives of junior high school chemistry curriculum. First, the junior high school chemistry ”transitional “ definition of the concept of so-called junior high school chemistry ”transitional “ concept (or ”stage "
