In face of challenges such as the fragmented, delayed updates, and difficulties in cross-cultural implementation of global digital education standards, the World Digital Education Alliance has issued an initiative and compiled the International Digital Education Standard System Framework 2025, providing theoretical support for forming a global consensus on the digital education standard system. This paper interpreted the document from five aspects: system framework review, construction principle, core model, localized application mechanism, and value commentary. Among them, this paper mainly elaborated on the three-dimensional model of the system framework, pointing out that this model consisted of business domains, business levels, and scenarios/topics, which can transform complex standardization needs into a visualized three-dimensional map. At the same time, it thoroughly analyzed the localized application mechanism centered on “layered application + demand matrix”. The interpretation work in this paper can offer theoretical reference and implementation pathways for various countries or regions in formulating digital education standard plans and promoting the localized application of digital education standards, thereby contributing to the understanding, adoption, and implementation of this system framework.

Virtual digital human has become a significant driving force for the digital transformation of education, and it is necessary to establish a standard system to ensure its application and development in the education field. Therefore, this paper clarified the concept of virtual digital human, analyzed its unique features in educational applications, and extracted the standardization requirements of educational virtual digital human from multiple demand use cases. Based on this, through the investigation of the current situation of the standardization of virtual digital human, this paper designed the standard system of educational virtual digital human, and planned the realization path of the standard system of educational virtual digital human in detail from six aspects of top-level design, future-oriented, application-driven, industry-academic collaboration, interdisciplinary integration and international cooperation. The standard system of educational virtual digital human can provide reference for the development of serial standards of educational virtual digital human, and its path planning can provide guidance for the educational application and innovation of virtual digital human, thereby promoting the digital transformation and upgrading of education.
