依据《普通高中信息技术课程标准（2017年版2020修订）》中“以学科大概念为核心”的要求，提出融入学习支架的信息技术大概念教学思路，具体阐述如何基于学习支架开发“数据编码”大概念项目，构建“认知—情感—技术”三阶学习支架模型，以“博物馆被盗案”项目为例介绍具体教学实践，最后说明教学实践效果并提出教学反思。

In accordance with the requirements outlined in the "Information Technology Curriculum Standards for Ordinary Senior High Schools(2017 Edition, 2020 Revision)", which emphasize a core focus on disciplinary big ideas, this paper proposes a teaching approach for Information Technology that integrates learning scaffolds. It elaborates on how to develop a big idea project centered on "data dncoding" based on these scaffolds. A three-phase learning scaffold model— "cognitive-emotional-technical" —is constructed to support student learning. The teaching practice is illustrated through a specific project example, "The Museum Theft Case". Finally, the paper discusses the observed outcomes of the teaching practice and offers reflections for further improvement.
