After continued debate over cellphones in schools, one local board has decided to ban the devices.

The Dufferin-Peel Catholic District School Board has voted to prohibit students from having the electronic gadgets turned on while on school property, in portables and during after-school sports and field trips.

The rule, which comes into effect Monday, also bans other popular but distractive hand-held devices including iPods and BlackBerrys.

"I understand you shouldn't have it in classes, but at least let us have it on us in case of an emergency," said Grade 11 student Natasha Fernandes, who attends Father Michael Goetz Catholic School in Mississauga.

Some parents echo Fernandes' stance, saying they feel comfortable knowing they can contact their children in case of an emergency or a dangerous situation, such as a school shooting.

Last week Toronto District School Board Trustee Josh Matlow told CTV News there should be policies in place with respect to cellphones, especially since newer models can help students cheat on tests and exams.

Education groups have expressed their concerns over privacy, as some phones with photo and video capability could be used to record in changerooms and washrooms.

In addition to etiquette, experts argue the devices are shortening students' attention spans.

"This isn't just about the individual, it's not just about 'my rights' or simply 'because I can,'" said Alan Mirabelli, executive director of the Vanier Institute of the Family in Ottawa.

"I operate in the context of a community, whether it's a classroom, or a business meeting or a family gathering, and so I need to consider what impact this is having on others."
