基于化学学科理解的教学——以“苯”为例

Teaching of Benzene Based on the Understanding of Chemistry Discipline

以“第一种人工合成染料苯胺紫”为素材创设情境,将煤、苯和染料苯胺紫等建立联系,由此引导学生探讨3个问题:“苯从哪里来”“如何确定苯的结构”及“如何解释苯的性质”,让学生在收获具体知识的同时,理解苯环结构的稳定性,了解苯的结构的研究历史背景以及苯环结构学说在有机化学发展史上的卓越作用。

Taking“the first synthetic dye aniline violet”as the material to create a situation,this paper establishes the connection between coal,benzene and aniline violet,and guides students to discuss three questions:“Where does benzene come from”“How to determine the structure of benzene”and“How to explain the properties of benzene”,to help students understand the stability of benzene ring structure,the historical background of benzene structure research and the outstanding role of benzene ring structure theory in the development history of organic chemistry while gaining specific knowledge.
