【摘要】 如何高质量开展疫情期间校内外师生、国外留学生线上线下同步教学，是当前很多高校面临的一大难题。为解决此问题，北京大学构建了全媒体教学资源中台系统。全媒体教学资源中台系统以服务为核心能力、以资源为驱动、以数据为抓手，形成了包含资源管理中台、服务业务中台和数据管理中台的“三位一体”教学资源大中台体系。文章分析了全媒体教学资源中台系统构建的理论基础，介绍了中台系统的一体化对接方案和组成模块，并探讨了中台系统在北京大学推进线上线下同步教学的实践成效，发现中台系统在建设理念、应用逻辑、发展模式等方面具有创新性。最后，文章针对全媒体教学资源中台系统与教育资源数字化的未来发展提出相关建议，以期探索出一条适用于高校教学资源整合、资源服务、资源共享的发展路径。更多还原

【Abstract】 How to carry out high-quality online and offline synchronous teaching for teachers and students inside and outside the school and foreign students during the COVID-19 pandemic is a major challenge faced by many colleges and universities. To address this problem, Peking University has established an Omnimedia Teaching Resources Middle-ground System. This system took service as the core competency, resources as the impetus, and data as the handle, and formed a “three-in-one” teaching resource middle-ground system which consisted of resource management middle-ground, services businesses middle-ground and data management middle-ground. This paper analyzed the theory basis for the construction of the Omnimedia Teaching Resources middle-ground system, introduced an integrated interfacing scheme and composition module, and discussed the practice effect of the middle-ground system on the promotion of online and offline synchronous teaching by Peking University. It was found that the middle-ground system was innovative in the construction concept, application logic and development model. In addition, suggestions for the future development of the Omnimedia Teaching Resources Middle-ground System and educational resources digitalization were proposed, in order to explore a development path suitable for college teaching in education resources integration, resources service and resources sharing.更多还原
