Ms Guo is a teacher from Ordos. She asked her students to hand in their homework through a OR code (二维码). “When students finish their homework, they keep it on WeChat. Then, each student makes his own QR code and gives it to me. So I can check their work using my computer or phone,” Ms Guo said.
When Guo scans (扫描) her students’ QR codes, their homework comes out on her phone. She finds that their homework becomes more creative (创造性的) with many pictures, music and even videos.
Guo’s students like the new way and think it is interesting. “Many students like to work with computers, which makes learning more fun,” said Tingting, a student of Guo’s.
“The paper is not easy to keep, but the code is easy to keep and share,” Guo said. However, some parents worry that their children will spend too much time on computers or phones.
They only use the code when they hand in their homework. It doesn’t take students too much time. For teachers they can check the students’ work at any time. And it’s also an easy way to share homework with other students.
