The digital education strategy continues to promote smart campuses, with a strong sense of technology (big data observation). From a blackboard and a podium to constantly enriching digital education application scenarios, the current construction of campus informatization is moving towards a new stage of application integration and innovation in smart campuses. What are the characteristics of a smart campus? What is the significance of improving teaching quality and transforming educational models? The reporter walked into some schools to see how new technologies can change the learning environment and serve the comprehensive growth of students. In the classroom, connected electronic screens can access high-quality courseware resources at any time; On the playground, intelligent sports equipment makes the ten minute break more interesting; Turn on your phone and you'll find all kinds of campus data and information available... A smart campus is full of technology. The 20th National Congress of the Communist Party of China included "digitalization of education" in its report for the first time, proposing to "promote digitalization of education and build a learning society and a learning country for lifelong learning for all.". Currently, the national education digitalization strategy is solidly advancing, and the construction of campus informatization is moving towards a new stage of intelligent campus with application integration and innovation. Schools at all levels and types actively explore the construction of smart campuses, open up new forms of education, enhance the digital literacy of teachers and students, and enable digital technology to serve comprehensive education. The basic infrastructure, equipment, and environment have been built in a primary school in Dongcheng District, Beijing, and fifth grade students are taking a doctoral research course. On the intelligent interactive screen of the classroom, the large bronze vessel Houmu Wuding is clearly displayed. Student Xing Chenyang gently slid his fingers on the interactive screen, and his stepmother Wu Ding rotated accordingly. "360 degree display!" Xing Chenyang said, "Even when visiting a museum, it is not easy to see the whole picture due to the influence of exhibition cabinets and lighting. Now we can zoom in high-definition on the screen and explore every detail in depth." "By using multiple technologies such as augmented reality, virtual reality, and cloud based digital computing, we have digitized the resources of the Chinese excellent traditional culture enlightenment course, introduced virtual scenes in museums, and built an immersive, interactive, and experiential classroom." Guo Zhibin, deputy principal of Shijia Primary School, introduced that the new teaching scene not only allows learning to browse and listen, but also cultivates students' abilities to observe, think, solve problems, and express opinions, promoting the development of core literacy. In the field of vocational education that places greater emphasis on practical operation, smart devices have significantly improved the quality of teaching. At the National Vocational Education Virtual Simulation Demonstration Training Base in Nanchang City, Jiangxi Province, equipment such as simulation airport towers, aircraft models, and engine models are readily available. "Wearing training glasses and holding an operating pen, you can see the internal structure of the machine equipment, and you can also manually disassemble and assemble it, which is very realistic and intuitive." The relevant person in charge of the development and operation department of the training base introduced that virtual simulation training has broken through spatial limitations in teaching, allowing students to improve their skills through low-cost repeated training. The construction of a smart campus cannot be separated from the continuous improvement of infrastructure. The infrastructure, equipment, and environment for smart education in our country have been basically completed. "Relying on network infrastructure such as gigabit optical network and 5G, smart campuses have achieved extensive connections between teachers, students, equipment, and educational resources." Zang Lei, Deputy Chief Engineer of the Institute of Technology and Standards at the China Academy of Information and Communications Technology, said, "Smart campuses provide new teaching methods such as online teaching, holographic classrooms, virtual simulation experiments, and practical training, integrating high-quality course resources and contextualized thematic resources into daily teaching, providing students with real and vivid learning scenarios, and building a learning mode that goes beyond physical classrooms and campus boundaries." Data analysis and diversified applications continuously enhance the physical education classes of Dinglan Second Primary School in Hangzhou, Zhejiang Province. While students practice standing long jump, the smart sports system on the side is also using six high-resolution, High frame rate cameras for students to take off Capture key nodes during landing and jumping in all directions and with multiple details. "The swing arm angle is too small", "the takeoff speed is slow", "one foot landing"... The system automatically recognizes student movements and reminds students to improve. The smart sports system can not only automatically collect and analyze action data, but also generate reports based on students' completion of sports. According to the report, teachers will have a scientific basis for teaching, and teaching evaluations will be more accurate Li Qingli, Deputy Director of the Education Information Resources Center of Shangcheng District Education College in Hangzhou, said. Data is a key element in the construction of smart campuses. Effective data analysis and application can help understand student status, achieve personalized services, discover teaching problems, and assist in scientific decision-making. At Tianjin No.19 Middle School, the shared space in the middle of the teaching building is the most popular leisure area for students. Principal Lu Dongmei shared the story of the school using data information to do a good job in project construction. Each of us students has a campus card and can borrow books from the school's drifting bookshelf. The drifting bookshelf has both borrowing and trajectory collection functions, and every time a student passes by with a campus card, they can collect a piece of data Lu Dongmei introduced that "data helps us identify students' behavioral habits and social needs. Based on trajectory data, we have built a shared space in a certain area in the middle of the teaching building, which has been passed through the most times and stayed for the longest time." With a focus on empowering education and teaching reform through education big data, and fully leveraging the support of data for smart campuses, the construction of the National Education Digital Big Data Center has begun. "On the one hand, we will expand the scope of operation and monitoring of the national smart education platform, expand the depth of monitoring; on the other hand, we will build a data governance platform, and empower various management services through various government data sharing, innovative new student registration, precise funding, smart ideological and political, campus security and other application scenarios." said the relevant person in charge of the Science, Technology and Information Technology Department of the Ministry of Education. The diverse needs of teachers and students have been quickly responded to by opening the "Smart Academy" mini program at Fudan University, "Chen Wangdao's Old Residence Visit", "Seal Engraving Workshop Seal Engraving Experience Activity", "The 5th Basketball Training Camp"... Various latest campus activities are in sight. "Click on the relevant link to make an appointment for participation, which is very convenient." Zhang Zixuan, a 2021 undergraduate student in the Department of History, said, "The 'Smart Academy' provides rich campus information and allows teachers and students to interact. Browsing, organizing, or participating in activities can earn different points to exchange for the academy's cultural and creative products, which enhances everyone's enthusiasm." "We hope to build a lightweight mini program to create a convenient window for academy promotion, a unified entrance for academy activities, and a good interface for teacher-student interaction." Fudan University Party Committee Student Work Department Director Ai Zhu introduced that based on talent cultivation goals and student growth needs, we are developing a new function for automatic and accurate promotion of educational resources to improve the accuracy of resource matching with students. The application of smart campus is also reflected in smart services and smart management. Zang Lei said, "By upgrading the campus management service platform and building a one-stop integrated information system that is interconnected, we can not only provide high-quality services for teachers and students in schools that respond quickly, but also help improve the school's management decision-making ability." After the event, the supplies can be quickly classified and returned to their original positions. The application developed by Shanghai Jianqing Experimental School makes the name, image, quantity and other information of each teaching aid clear at a glance, not only convenient for access and use, but also provides reference for schools to purchase supplies and teachers to choose equipment; With one click appointment and facial recognition, the smart venue appointment system of Harbin Institute of Technology has greatly improved the efficiency of sports venues... Nowadays, a smart campus that everyone participates in, builds, and enjoys is becoming the new normal. "At present, as a supply side education informationization enterprise, a variety of smart campus products have been launched, but many products have not yet touched the real needs and pain points of campus users, and scene design and business capabilities still need to be improved." Zang Lei stated that we should strengthen the connection between supply and demand, accelerate the development of customized smart campus products, better match the diverse needs of schools, and enhance the user experience of teachers and students.
