核心素养导向的初中生物学重要概念教学

Important concepts teaching in junior high schoolbiology centered on core literacy

以“人体通过呼吸系统与外界进行气体交换”为例,阐释重要概念是连接大概念与次位概念的脚手架,纵向通过重要概念承上启下,横向可将大概念体系中平行的重要概念相互关联,通过情境体验、图文转化、多学科融合等策略,帮助学生构建大概念体系,形成生命观念,养成核心素养。

Taking“the human body exchanges gases with the external environment through the respiratory system”as an example,this paper presents that the important concepts act as scaffolds that connect the main concepts with the subordinate ones.Vertically,they serve to bridge and contextualize the broader conceptual framework.Horizontally,they interlink significant concepts within the overarching system.Through strategies such as contextual experience,visual representation,and interdisciplinary integration,it helps students shape a main concept system,form a concept of life,and develop core literacy.
