It is understood that Chaoyang Experimental Primary School began to introduce 3D printers from 20 14 and set up a comprehensive practical course of 3D printing. In class, students spontaneously form groups to study 3D printed educational toys. As four traditional educational toys in China and an important part of traditional culture in China, Lubansuo has always been loved by students. However, the manufacturing process of six Luban locks on the market now is rather troublesome, and the splicing steps are complicated, so it is almost impossible to complete the splicing without schematic diagram. Qiu Hejia, a design member, said, "We found that the' Luban Lock' actually used the tenon-mortise principle, and it was migrated and deduced through the 16 block structure of the ancient Luban Lock, and it was reduced to six pieces now, of which four pieces were relatively pieced together and two pieces were fixed. It can make younger students easier to get started and more interested in playing. "
The Luban lock made by primary school students won the national patent, which is also a microcosm of the achievements of school curriculum reform. According to Hu, secretary of the Party branch of Chaoyang Experimental Primary School, the school started the curriculum reform from 20 10, and students can participate in choosing their own courses and teachers from the first grade. Since September this year, the teaching reform of "walking to school by class" has been carried out in three campuses, which have nearly 400 elective subjects. "The rich elective courses offered by the school aim to provide students with diversified development opportunities and build a richer growth platform for students." Hu said:
