Abstract：To address the practical challenges in improving vocational college teachers' digital literacy,such as fragmented platforms,redundant resource construction,and insufficient training targeting,and to facilitate the digital transformation of education,a closed-loop hierarchical empowerment model of"diagnosis-adaptation-reconstruction-evolution"was constructed based on the hierarchical task network(HTN)theory and combined with the practice of the"Zhike"platform.Teachers'digital literacy was divided into three levels(novice,competent,and expert)in the model,and corresponding three-level task chains(basic,intermediate,and advanced)were designed.The large artificial intelligence(AI)models and multi-source resources were integrated to form a four-dimensional linkage mechanism of"technology-resources-scenarios-evaluation".A controlled experiment was conducted with 1256 vocational college teachers as subjects.The results showed that the digital literacy of teachers in the experimental group relying on the platform was improved by 22.1%,which was 10.1 percentage points higher than the improvement in the control group.Among all dimensions,the"digital teaching application"dimension achieved the most remarkable progress,and 85%of the teachers recognized that the tasks were highly consistent with teaching needs.This study provided an operable and replicable path for the large-scale and precise improvement of vocational college teachers' digital literacy,offering strong support for the development of teachers'capabilities in the digital transformation of education.
