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 Mr. 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 cheek their work
anywhere using my computer or telephone. "
The QR codes can be sent to Mr. Guo by email,
QQ and WeChat. When Mr. Guo scans (扫描) his students' QR codes, their homework appears on his phone, lie
finds that their homework becomes more creative, with many pictures, music and
even videos.
Mr. 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
Tingling, a student of Mr. Guo's.
"The paper is not
easy to keep, hut the code is easy to keep and share." Mr. 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 cheek the students' work at any time. And it's also an easy way to share homework
with other students.
