Mr. Guo is a teacher from Xi'an. He asked his students to hand in their homework through a QR code(二维码). "We spent an hour or two in class learning how to generate(使产生) the codes, and in the end everything gets easier." Said Guo, "When students finish the 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 anywhere using my computer or telephone."

    The QR codes can be sent to Mr. Guo by email, QQ and WeChat. When Guo scans(扫描) his students' QR codes, their homework appears on his phone. He finds that their homework becomes more creative, with many pictures, music and even videos.

    Guo's students like the new way and think it is interesting. "We are living in the information age. 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, "It is worth trying to use new technology in education. Education itself is a kind of creation. I don't want my students to fall behind the times."

    However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it's unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the codes when they hand in their work, which doesn't take them too much time. Also for teachers, it allows them to check the students' work at any time. And it's also an easy way to share homework with other students.
