网络学习空间是信息技术与学习科学深度融合的产物，教师网络学习空间的应用效能对促进数字化教学有较强 的现实意义。通过对相关文献回顾，结合专家访谈，运用解释结构模型构建影响中小学教师网络学习空间应用效能的层级递 阶结构模型。研究表明：空间资源、自我效能感、感知有用性是影响教师应用网络学习空间的直接因素；学校的观念、相关政策 支持是基本影响因素；教师相关培训、基础设施条件、空间管理、教师激励策略等是间接影响因素。在结构特征分析基础上给 出相关建议，为促进中小学教师网络学习空间建设和应用高质量发展提供参考。

Network learning space is the product of the deep integration of information technology and learning science. The application efficiency of teachers' network learning space has a strong practical significance in promoting digital teaching. Based on the review of relevant literature, combined with expert interviews, this paper uses Interpretative Structural Modeling to build a hierarchical structure model that affects the effectiveness of online learning space application of primary and secondary school teachers. The research shows that space resources, self-efficacy, perceived usefulness are the direct factors that affect teachers' use of online learning space; School concept and the support of relevant policies are the basic influencing factors; Teacher related training, infrastructure conditions, space management, teacher incentive strategies and so on are indirect influencing factors. Based on the analysis of the structural characteristics, this paper gives some suggestions to promote the construction and high-quality development of online learning space for primary and secondary school teachers.
