基于境脉教学的初中生物学教学设计——以“多种多样的生态系统”为例

Junior High School Biology Teaching Design Based on Contextual Teaching—Taking “Diverse Ecosystems” as an Example

摘要: 本文基于境脉教学理念，以苏科版初中生物学七年级上册“多种多样的生态系统”一节为例，围绕江苏省苏州市张家港市“张家港湾生态蝶变”创设整体性主题情境，构建“情境链–任务链–知识链”相贯通的境脉教学设计框架，引导学生在连续递进的学习活动中自主建构生态系统的知识体系，实现知识的整合重构与迁移应用，促进生物学学科核心素养的落地与提升。

Abstract: Based on the concept of contextual teaching, this paper uses the section “Diverse Ecosystems” from the Grade 7 biology textbook (Jiangsu Science and Technology Press, Suke Edition) as an example. It creates a holistic thematic context centered on the ecological transformation of Zhangjiawan Bay in Zhangjiagang, Suzhou, Jiangsu Province, and constructs a contextual instructional design framework that interconnects a context chain, a task chain, and a knowledge chain. This design guides students to independently construct the knowledge system of ecosystems through continuous and progressive learning activities, facilitates the integration, reconstruction, transfer, and application of knowledge, and promotes the practical implementation and enhancement of biology core competencies.
