碳元素教学中化学学科素养之宏微关联与变化平衡思想

The Thought of Macro-micro Correlation and the Change-balance Idea of Chemical Literacy in Carbon Element Teaching

通过对金刚石与石墨的宏观性质与微观结构的逻辑关联的讨论,阐释化学学科核心素养中的宏观辨识与微观探析及其思想方法;此外,通过对石墨烯在高压这一极端物理条件下转化为钻石烯这一新颖碳纳米结构的物理化学过程特征及化学史的剖析,以阐释化学学科核心素养中的变化观念与平衡思想。

This paper discusses the logical relationship between the macro properties and microstructure of diamond and graphite in order to explain the macro identification and micro analysis in the core literacy of chemistry.In addition,through the analysis of the physicochemical process characteristics and chemical history of the novel carbon nanostructure of graphene transfering into the diamond under the extreme physical condition of high pressure,the concept of change and balance in the core literacy of chemistry are explained.
