基于情感缺失视角下的化学史微课教学设计研究——以空气组成的发现为例

Research on the Teaching Design of Chemistry History Based on the Perspective of the Lack of Emotion—A Case Study of the Discovery of Air Composition

我国微课教学和化学史教学一直以来存在着诸多问题。基于微课平台进行化学史教育,不仅有利于推动微课建设,更有利于将我国化学史教学推向更高水平。文章结合微课和化学史教学的共性和个性给出了三条具体理由:(1)化学史有利于解决微课中的情感缺失问题;(2)微课的多媒体形式和短小新颖特点,能使化学史更好地应用于课堂中,有利于改变传统化学史教学的边缘化地位;(3)微课有利于集中一两个化学史的知识点学习,学生更易理解和掌握。实现上述三点,需要基于二者共性和个性进行整体的化学史微课教学设计,并给出化学史微课教学设计"空气组成的发现"具体案例,以期推动我国化学史微课教学走向新台阶。

There are many problems in China＇s micro teaching and the teaching of the history of chemistry. The education of chemical history is not only conducive to promote the micro-class constructions, but also conducive to the history of Chemistry Teaching to a higher level based on micro education platform. The paper gives based on commonness and individuality of micro courses three specific reasons： （l）History of chemistry is conducive to resolving the lack of emotion problems in the micro course. （2）Micro-class multimedia forms and short, novel features, can make better use of chemical history in class, which is conducive to change the marginalized status of traditional teaching of chemistry history.（3）Micro class is fit to focus one or two knowledge learning of chemistry history, so that students more easily understand and grasp. To achieve the above three points, integrative micro teaching designs of history of chemistry need to be made based on the commonness and individuality. One example of history of chemistry micro-class teaching design of the discovery of air composition to promote the micro-class teaching and chemical history in our country to a new level.
