On September 14, the reporter learned from a primary school in Chaoyang District, Beijing that Yang Jialin, Chou He Jia and Cheng Kexin, the graduates of this school, won the patent certificate of design issued by China National Intellectual Property Administration in the fourth grade for their classroom learning work-3D printing luban lock. ?
Luban Lock is an ancient educational toy for children in China. According to legend, it was invented by Lu Ban from the late Spring and Autumn Period to the early Warring States Period. It is one of the four traditional educational toys in China, and has a history of thousands of years. Teachers in this school often recommend these traditional educational toys to students, and many students are interested in learning educational toys. ?
Yang Jialin, Chou He Jia and Cheng Kexin are now in middle schools, but their experience of making Luban locks in primary schools is still vivid. Chou He Jia told reporters, "We found that' Luban Lock' adopts the tenon-mortise principle and has nine structures." Three of them are fixed, so they simplified the structure and designed a six-structure "Luban lock". After several adjustments, Qiu Hejia and his friends made a perfect "work" through 3D printing technology. The Luban lock they made won the love of the students and was praised by the students as "the most suitable Luban lock for primary school students." ?
The Luban lock made by primary school students won the national patent, which reflected the achievements of school curriculum reform. It is reported that the primary school began curriculum reform from 20 10, and initially formed a curriculum system with the concept of "happy education". In other courses except Chinese, mathematics and English, students can participate in choosing their own courses and teachers from grade one. Since September this year, students from three campuses of the school have accumulated nearly 400 elective subjects. ?
