大概念下的碎片教学重组设计—以初中化学“酸碱盐”学习主题为例

Reorganization Design of Fragmented Teaching under the Big Concept: Taking the Learning Topic of “Acid, alkaline and Salt” in Junior High School Chemistry as an Example

The big concept, from the perspective of what to teach, addresses the issue of students’ knowledge being both extensive and fragmented. Guided by the big concept, this paper promotes core chemical literacy through various thinking methods, rationally and skillfully reorders the teaching sequence, and implements a fragmented teaching reorganization design. This approach enhances educational depth, structures and systematizes students’ knowledge, encourages holistic exploration, and fosters development in areas like chemical knowledge, thinking skills, and values.

大概念，基于“教什么”的视角解决学生所学知识的“多”而“散”问题。本文在大概念的指导下，通过多种思维方法提升化学核心素养，将教学顺序进行合理且巧妙地调整，完成大概念指导下的碎片化教学重组设计，这能够适当提升教学深度让学生的知识更加结构化、系统化，让学生从整体视角进行探究，在化学知识、思维方法和价值观等多方面获得发展。
