A few days ago, in the third "Love and Profession" activity in the first season of "Teacher Talk" in Guangzhou in the new era, held by the Bay Area Experimental School in Nansha District, Guangzhou, the digital twin wisdom teacher training meta-universe platform developed by Guangzhou Open University was officially released. This is one of the first practical projects of educational metauniverse in national colleges and universities, and it also marks an important step for Guangzhou Open University to comprehensively promote educational intelligence, explore the educational model of metauniverse, and promote the professional development of teachers in Guangzhou.
As the main implementation unit of Guangzhou’s "Pilot Area of Artificial Intelligence Boosting Teacher Team Construction of the Ministry of Education", Guangzhou Open University actively builds a regional teacher development big data center and artificial intelligence engine, expands the platform and resources of teacher education through multiple channels, builds a "smart teacher training" system for primary and secondary school teachers, and promotes the in-depth integration of new technologies and education and teaching. And through the collaborative innovation of enterprise alliance, we cooperated with China Telecom to research and develop the "Wisdom Teacher Training Metauniverse", which achieved remarkable results in the construction and application of Metauniverse. In 2022, the "5G+ Metauniverse Wisdom Teacher Training Construction" project won the third prize of the fifth "Blooming Cup" 5G Application Collection Competition of the Ministry of Industry and Information Technology. In 2023, the project "5G+ Wisdom Teacher Training Meta-Universe Platform Helps the Construction of Primary and Secondary School Teachers" won the third prize of the first "Xingzhi Cup" National Artificial Intelligence Innovation and Application Competition on Ecological Construction sponsored by the Ministry of Industry and Information Technology and the Ministry of Science and Technology.
Guangzhou Open University and China Telecom’s technical team set up a digital twin metacosmic scene platform for this activity for the first time. From the aspects of technology, adaptation, scene, function and other applications, the functional applications of learning, socializing, meeting, activities and other scenes in the metacosmic space were fully demonstrated, providing more than 40 online teachers and offline participants with an immersive experience of three-dimensional, virtual and real integration and multi-sensory interaction. On-site participants can not only roam the virtual venue through the big screens on both sides of the venue, but also wear VR equipment in the meta-universe experience activity area to experience the virtual venue space; At the same time, online participants who enter the teacher’s meta-universe space can choose digital virtual characters to sit down and listen to lectures, realistically reproduce the real scene of the venue, build a three-dimensional integrated space scene, and immerse the meta-universe venue with real-time online interaction.
In this activity, Guangzhou Open University showed the participants the application functions of the "Wisdom Teacher Training Metauniverse" platform, mainly in the following aspects:
In the technical application, through the wisdom teacher training the scene construction ability of the cloud platform in the meta-universe, the layout of virtual space scenes, characters and content elements is built; Engineering development of 3D content and business logic through the key technology and capability base of cloud platform in the meta-universe; Support flexible deployment methods such as public cloud, private cloud and hybrid cloud through the convergence ability of platform and cloud network in the meta-universe cloud; Through digital multimedia technologies such as VR and digital twinning, 3D modeling is carried out for teaching and training elements such as characters, environment and props to create a multi-dimensional immersive classroom; Using artificial intelligence, speech recognition and other technologies to enhance the interactive effect.
In the adaptation application, the digital twin wisdom teacher training meta-universe adopts communication technologies such as 5G communication and cloud network convergence to broaden the application dimension, and supports multi-terminal access experiences such as mobile phone, VR, PC and cloud rendering.
In the scene application, according to the original teaching and training scenes, the design innovation was carried out, and technologies such as 5G, VR, digital reconstruction, live broadcast and virtual digital were used to create a number of immersive online education and training scenes for the first time, namely: public service hall (customized classroom of Education Bureau), ladder classroom (meta-universe classroom) (classroom teaching theme), conference discussion room (meta-universe interactive room) (interactive discussion and training) and school auditorium (meta-universe).
In terms of functional application, the built scenes all support multi-person online collaboration in different places, and realize multi-person communication, discussion, interaction and other activities.
The event was broadcast live online to teachers in the city, and more than 400,000 viewers attended the event online, witnessing the application of the digital twin wisdom teacher training meta-cosmic technology, which was a complete success. In order to break the limitation of geography and time and space, realize the new format of online and offline integrated teaching and research in different places, and solve the problem of unbalanced educational development between regions, schools and urban and rural areas, a successful social experiment was carried out, which was an important practice for further promoting the construction of teachers’ team with new technologies such as artificial intelligence, empowering educational innovation, and promoting the modernization of education in Guangzhou with the high-quality development of "smart teacher training".
