基于境脉教学的高中生物学教学设计——以“特异性免疫”为例

High School Biology Teaching Design Based on Contextual Teaching—Taking “Specific Immunity” as an Example

摘要: 本文基于境脉教学理念，以“特异性免疫”为例，围绕“校园流感事件”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，引导学生在连续递进的学习活动中建构特异性免疫的知识框架，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发展与提升。

Abstract: Based on the contextual teaching concept, this paper takes “specific immunity” as an example and creates a holistic thematic context around the “campus flu incident”. It constructs a contextual teaching design that connects the “context chain-task chain-knowledge chain”, guides students to build a knowledge framework of specific immunity in a continuous and progressive learning activity, realizes knowledge integration, reconstruction and transfer application, and promotes the comprehensive development and improvement of the core competencies of biology.
