Nanjing Tech University in Nanjing, East China's Jiangsu province had developed a series of experiential courses in the fall semester of 2022 which have proved popular among its students.
Among the courses is one related to reverse cultural relic restoration, which refers to deriving the original model of a relic from its fragments. During the class, students learn to use 3D scanners, 3D printers, and software to create high-precision 3D models of relics' fragments before putting them together.
This reverse restoration technology is efficient, precise and will not cause damage to the relics, said Mi Tian, who teaches the course.
In a class on gravity car (a model car solely powered by gravitational potential energy), students learn about the carbon-free car's structure and how it works, and get to draw designs as well as assemble the parts.
A course that teaches students how to turn aluminum scraps into transmissions has also been offered.
Wang Hongzhou, deputy Party chief of the university's School of Energy Science and Engineering, said such hands-on courses will improve students' abilities to troubleshoot, innovate, and cooperate.
