    French children are saying "Hello" to the new academic year and "Bye" to their cell phones during school hours． That's because a new law has come into effect which bans phone use by students up to the age of 15． The legislation， which follows a campaign promise by French President Emmanuel Macron， also bans tablets and smart watches．

The ban is also in place at break times， with exceptions in cases of emergency and for disabled children， the French Education Ministry said in a statement． In emergencies， students can ask their teachers for permission to use their phones． Meanwhile， high schools can voluntarily carry out the measure．

Education Minister Jean-Michel Blanquer said the new rules aim to help children focus on lessons， better socialize and reduce social media use． The ban is also designed to fight online bullying and prevent thefts and violence in school． Blanquer has claimed the legislation would improve discipline among France's 12 million school students， nearly 90% of whom have mobile phones． "Being open to technologies of the future doesn't mean we have to accept all their uses，" Blanquer said in June as the bill was going through in Parliament．

As for enforcement， it's up to individual school administrations to decide how to put through the ban． School principals can decide to store students' phones in lockers or allow them to keep them， switched off， in their backpacks． The law allows teachers to take away the phones until the end of the day in case of someone disobeying the bans．

Jacqueline Kay-Cessou， whose 14-year-old son， David， is entering eighth grade at the Camille See International School， told the reporter she was happy to hear of the ban． "It's fantastic news． It's something I've wanted for years，" Kay-Ccssou said． "I think phones are socially harmful． Kids can't think and sit still anymore and it's highly addictive．"
