More teachers than ever before say they are being secretly recorded by students. One in three - eight per cent more than last year - said they or their colleagues had been secretly filmed by students in the classroom, according to a survey from the Federation of Education Workers.
The group asked 207 principals and teachers of primary and secondary schools about unknown video or audio recording in schools. One in four - 25 per cent - said they were secretly recorded by students in public areas such as playgrounds and corridors. The figure for last year was 15 per cent. In all cases, the teacher found out about the recording afterwards.
Almost 75 per cent of the teachers who were interviewed were worried about being filmed or secretly recorded, up from 64 per cent last year.
Wong Wai-shing, a federation vice-chairman, said the increase might be because each year more students have smart gadgets.
"It is more convenient [to take photos] with electronic products," Wong said. "Phones, watches and music players can all take photos or shoot videos."
Wu Siu-wai, another vice-chairman of the federation, said secret filming was disrespectful of others' privacy.
Spreading the recorded clips or photos has also slightly increased, as 32 per cent of teachers said recorded clips of students had been made public on social media such as Facebook and WhatsApp. Meanwhile, 21 per cent - five per cent more than last year - said clips of teachers had been posted online.
The popularity of mobile apps or social media sites with students creates new issues that schools are still trying to understand. CNEC Lau Wing Sang Secondary School's circular, which reminded students about the proper use of WhatsApp or Facebook, has recently gone viral. The circular warned students not to copy homework through WhatsApp, or wander the streets after school.
Some netizens say the school is threatening students' privacy and freedom. The school did not reply to Young Post inquiries.
