Does the evidence support a school ban on smartphones?

The Government has advised schools to restrict the use of smartphones by students. This seems to be supported by the current evidence which suggests that restrictions of phone use can benefit student performance. But calls to ban smartphones in schools are unhelpful and prevent a more nuanced conversation to be had and further evidence to be collected around the benefits and risks of this technology to children, argue Miriam Rahali, Beeban Kidron and Sonia Livingstone as a result of a newly published report.
