Britain could ban smartphones and other personal electronic devices, like tablets, from the classroom over fears that they cause too much disruption to lessons.
Behaviour expert Tom Bennett is to look into the impact of devices used by pupils under an expansion of his investigation into how to train teachers to tackle poor behaviour, Schools Minister Nick Gibb said.
It follows concerns raised by schools inspectorate Ofsted over secondary-aged pupils using their phones at school.
Mr Bennett said: "Technology is transforming society and even classrooms - but all too often we hear of lessons being disrupted by the temptation of the smartphone.
"Learning is hard work and children are all too aware of this. So when they have a smartphone in their pocket that offers instant entertainment and reward, they can be easily distracted from their work.
"This is a 21st-century problem and most schools deal with it effectively. But I will now probe deeper into this issue."
In May, London School of Economics academics released a study of schools in Birmingham, London, Leicester and Manchester, which suggested that restricting mobile phone use could improve results.
