以系统论为指导，构建“一体五段”教师数字素养提升机制。“一体”突出系统性，整合各环节形成有机整体；“五段”涵盖价值引领、专题研修、学科融合、课程支持、评价改进，五段既层层递进又循环迭代，形成螺旋上升的闭环系统。西岗区实践表明，该机制能够显著提升教师的数字素养，为可持续的教师数字素养发展提供可复制的系统路径。

Guided by system theory, this study constructs a “One Core-Five Stages” mechanism for enhancing teachers' digital literacy. The “One Core” emphasizes systemic integration, unifying all components into an organic whole. The “Five Stages” encompasses value-driven guidance, specialized training, subject integration, curriculum support, and evaluation-driven improvement. These stages progress sequentially and also cycle iteratively, forming a closed-loop system of spiraling advancement. The practice in Xigang district demonstrates that this mechanism significantly enhances teachers' digital literacy, providing a replicable systemic pathway for the sustainable development of teachers' digital literacy.
