The culture secretary has called on more schools to ban mobile phones.

Matt Hancock said he admired those headteachers who did not allow their use during the school day and linked social media use with the problem of bullying among young children.

Hancock told the Guardian last week that he does not allow his children to have their own phones or to use social media, but dismissed the idea of legislating to stop their use in schools.

And, he returned to the subject in an article for Wednesday’s Daily Telegraph, in which he put the onus on headteachers.

He said: “Technology makes being a parent much harder. And schools have a big role too. I enthusiastically support using technology for teaching. But we also need to teach children how to stay safe with technology. Why do young children need phones in schools?

“There are a number of schools across the country that simply don’t allow them. I believe that very young children don’t need to have access to social media. While it is up to individual schools to decide rather than government, I admire headteachers who do not allow mobiles to be used during the school day. I encourage more schools to follow their lead. The evidence is that banning phones in schools works.

“Studies have shown mobile phones can have a real impact on working memory and fluid intelligence, even if the phone is on a table or in a bag.”

Quick Guide Children and tech Show Children and tech Laws governing children's relationship with technology vary worldwide, and are rarely enforced. The de facto age for many online services is 13, set by the US Children’s Online Privacy Protection Act in 1998, which prevents sites from targeting children, or knowingly allowing children to provide information online without parental consent. The burden of garnering that consent and the low returns for building services for children has meant, however, that providers tended to turn a blind eye to under-13s on their sites, neither catering for them nor policing their presence. That said, tech aimed more explicitly at children has blossomed recently, and legislation that aims to protect children from potential harm has been passed. Schoolchildren in France are barred by law from using their phones in school. Such laws are countered by efforts on the part of companies such as Facebook and Google to attract new users while young. Facebook offers Messenger Kids, which lets children speak to contacts vetted by their parents, while Google’s YouTube has a Kids app that offers copious parental controls and the ability to filter videos for all but the most child-safe content – although the filters, which are run by an algorithm, haven’t always been successful, prompting the company to announce a human-curated version. Proposed guidelines to improve child internet safety in the UK from the Information Commissioner’s Office in their 'Age appropriate design code' include: Disabling 'nudge' techniques designed to keep children online for longer like 'streaks' on Snapchat or Facebook 'likes'



Limiting how children’s personal data is collected, used and shared by social media companies.

Making “high privacy” the default setting for children using social media platforms, including disabling geolocation tools and targeted advertising as standard, unless there is a compelling reason not to.

Requiring social media companies to show that all staff involved in the design and development of services likely to be used by children comply with the code of practice.

Introducing robust age verification checks on platforms or treat all users as if they are children.

Last week, Hancock – whose brief includes digital policy – told the Guardian he believed “parents have a responsibility to ensure that children use technology appropriately. For instance, I allow my children to do their homework online, but I don’t let them on to social media”.

He added: “They don’t have access to the devices. They don’t have phones. Why do they need phones? They’re children, they’re 11.”

Hancock said the government had a responsibility to ensure internet companies “properly police their own terms and conditions”. But he dismissed suggestions the UK government should follow the lead of its French counterpart, which has banned mobile phones on school premises.

In his Telegraph article, Hancock said: “Modern digital technology is a powerful force for good ... But with all of the exciting doors that the internet opens, like any new technology it brings challenges, especially for our children.

“We all recognise children need more protection on the internet. If a child is being bullied during the day and they have access to social media, the bullying doesn’t necessarily stop when they walk out of the school gate. I want bullying to be as unacceptable online as it is in the playground.”
