Should naughty schoolchildren be fined?

A middle school teacher in Wenzhou, Zhejiang province, has proposed a controversial way to keep her students focused in class - fines for misbehavior. As for those who behave well, they can get a cash reward.

For example, if a student is caught using a mobile phone during class, he or she has to pay 100 yuan ($15).

The teacher said she started the system in the second half of 2015 and got support from the students' parents. Every month, she posts student records for parents to see.
