从一节化学展示课的设计方面进行评价分析,对当前化学课堂存在的现状进行了一些概括性的介绍。为了改变现状,追求高效率的课堂,教师应立足于隐形财富的积累。一方面,教师可从日常教学中不断提高学科素养,加强对日常教学中的反思和提升,在课堂中善于捕捉偶发情况等方面积累财富,丰腴自身教学上的隐形财富。另一方面,从整合教学内容、追求简便得当教学方法、教学素材的选择、优化课堂对话方式等方面进行了一些探讨,并结合课例和教学实践进行了分析。
From the aspect of the design and evaluation of a chemical display class, this paper gives some general introduction to the current status of the existing chemistry class. In order to change the status quo, the pursuit of efficient classroom, teachers should be based on the accumulation of invisible wealth. On the one hand, teachers can continuously improve their academic literacy in everyday teaching, strengthen their reflection and promotion in their daily teaching, accumulate wealth in catching occasional situations in class, and enrich their invisible wealth in teaching. On the other hand, some discussions are made on the aspects of integrating teaching contents, pursuing simple and appropriate teaching methods, selecting teaching materials, and optimizing classroom dialogues. Based on the case studies and teaching practices, some analyzes are made.
