基于TDBU模式的跨学科实践活动——以苏科版七上生物学教材为例

Interdisciplinary Practical Activities Based on the TDBU Model—A Case Study of the Grade 7 Biology Textbook in the Suke Edition

摘要: 新课标要求通过“生物学与社会·跨学科实践活动”主题的学习，学生能够理解多学科之间的相互联系，并运用多学科的知识和方法解决现实问题或生产特定产品，进而增强学生综合能力，发展学科核心素养。基于TDBU (top-down & bottom-up)模式开展“自制水族箱，饲养金鱼”活动，以学习小组形式参与并完成由若干相关模块精心设计整合而成的完整项目，能极大地培养学生实践能力和团队协作精神，提升核心素养。

Abstract: The new curriculum standards require that through the study of the “Biology and Society: Interdisciplinary Practical Activities” theme, students should comprehend interdisciplinary connections and apply multidisciplinary knowledge and methods to solve real-world problems or create specific products, thereby enhancing comprehensive competencies and fostering core disciplinary literacy. By adopting the TDBU (top-down & bottom-up) model to implement the “Design and Maintenance of a Homemade Aquarium for Goldfish” activity, students work in learning groups to collaboratively complete a holistic project comprising meticulously designed, interconnected modules. This approach effectively cultivates practical skills, teamwork spirit, and elevates core disciplinary competencies.
