The educational metaverse needs to seamlessly integrate with reality. According to Yang Sa, a journalist from Guangming Daily, in today's world, technological progress is rapidly changing, and modern information technologies such as the Internet and cloud computing are profoundly changing the way humans think and learn. How to adapt to the development of information technology, promote educational reform and innovation, and build a learning society where everyone can learn, everywhere can learn, and always can learn is a major issue that humanity is facing together. The 20th National Congress of the Communist Party of China included "promoting the digitization of education" in the report, proposing "promoting the digitization of education, building a learning society and a learning country for lifelong learning for all", marking that promoting the digitization of education has become a universal consensus and important strategic goal of the entire Party and the whole country. Regarding this, this version focuses on the emerging field of educational technology, the educational metaverse, and invites experts and scholars to jointly solve it. The concept of "metaverse" has attracted countless attention since its inception. Recently, the Ministry of Industry and Information Technology, the Ministry of Education and other five departments jointly issued the "Three Year Action Plan for the Innovation and Development of the Metaverse Industry (2023-2025)", which emphasizes "promoting the construction of virtual classrooms, virtual laboratories and other educational and teaching environments, encouraging the sharing of virtual simulation experiment training resources through platforms, and expanding the coverage of high-quality educational resources". As one of the most important application fields, the educational metaverse is accelerating its development and gradually entering the vision of more people. What is the educational metaverse? Experts introduce that it is the application of the metaverse in the field of education, that is, educational activities are carried out in scenarios created using metaverse technology and integrating virtual and real worlds. It has the main characteristics of "immersive experience, online socializing, group creation, and virtual and real symbiosis". What are the current applications and effectiveness of the educational metaverse? What other challenges does its development face? On May 23rd, at the Artificial Intelligence Learning Experience Center in Qingzhou City, Shandong Province, elementary school students intuitively experienced the origin of the Earth. The 2023 National Simulation and Innovation Application Competition, hosted by the Talent Exchange Center of the Ministry of Industry and Information Technology, is about to enter the finals. The relevant person in charge of the center stated that this competition adheres to the idea of integrating industry, education, and talent. It promotes learning, research, and application through competitions, starting from the upstream and downstream of the industrial chain, to help China's simulation industry develop rapidly. The competition provides' simulation answers' to cutting-edge scientific issues, engineering technology challenges, and industrial technology issues that will lead future technological development. Simulation technology can not only be applied to digital teaching, but also play an important role in fields such as medicine and chemical engineering. In addition, what are the cutting-edge applications of the educational metaverse? Liu Jing, Deputy Director of the Institute of Educational Technology, School of Education, Capital Normal University, introduced that the academic community divides the architecture of the educational metaverse system into infrastructure layer, operation platform layer, rule mechanism layer, and pattern application layer. The application and development of the educational metaverse are mainly reflected in the mode application layer - supported by technologies such as virtual reality, big data, and artificial intelligence, deeply integrated with the educational and teaching environment, providing specific scenarios such as virtual simulation, XR teaching, and intelligent teaching for teachers and students. For example, the national virtual simulation experimental teaching course sharing platform built by the Ministry of Education currently has 3514 experiments
