As a teacher, I know the damage phones do to kids. But this new ban won’t make a shred of difference | Nadeine Asbali

Most schools in England already ban mobiles. If it wants to make a change, the government should fund youth clubs and social activities

Look around next time you are out and you will see that children's addiction to smartphones nowadays often begins long before they've started school. By the age of 12, 97% of children will own their own phone. There is a growing body of evidence pointing to an alarming link between the time children spend on smartphones, and the access they provide to social media, with the likelihood of experiencing bullying, problems with self-esteem and even self-harm. So, in a bid to curb the damage to the next generation, the government has now issued statutory guidance on prohibiting their use in schools altogether.

As a (reluctantly) online millennial, I grew up alongside the internet. Our relationship has developed from chatting on MSN and playing Club Penguin on the clunky PC in the corner of the dining room (so long as my mum didn't need to use the landline), to the iPhone that now lives in my pocket, seems as attached to my body as my own limbs and contains much of what I need to survive. But I am also a secondary school teacher, and you only need a single break-time spent dealing with the drama caused by a social-media comment to conclude that phones in the classroom bring nothing but disruption to what should be a calm and safe place of learning.
