学史明理 学史增信——以“奇妙的二氧化碳”教学中的科学史实情境应用为例

Learning History of Science to Gain Knowledge and Boost Confidence:Applying Historic Facts in Science to the Instruction of “Wondrous Carbon Dioxide”

以人类认识二氧化碳知识的形成与发展史实为问题线索和教学主线,进行教学情境设计,探索利用科学史知识,从宏观认识上提升学生对二氧化碳性质的理解,促进学生初步建立学习常见物质的基本思路和方法的有效路径,为初中化学教师教学提供参考借鉴。

Using historical facts related to the formation and development of human knowledge about carbon dioxide as question clue and main teaching thread, the teaching situation was designed, in which the history of science was utilized to help improve students’ general understanding of properties of carbon dioxide and facilitate them to preliminarily establish a basic route and method to learn everyday substances. The study provided a reference for classroom teaching of chemistry teachers in junior high schools.
