New approach to calling the roll

A journalism lecturer at Changsha University of Science and Technology in Hunan province has built a Wi-Fi system for students joining the local network to replace the traditional way of calling the roll, Sanxiang City Express reported.

The lecturer, who teaches a new media course, intends to have Internet thinking involved in traditional classes but despite his innovative thinking, he cannot identify those who don't attend class although he can find out the number of students showing up.
