Newington College has joined a growing number of schools banning mobile phones, saying they lead to lower concentration, higher stress and "warped views on reality". The inner west school told students to keep phones in their lockers from the beginning of term four after an attempt to encourage boys to use them responsibly failed. But bans remain divisive, with both the NSW P&C and teachers union telling a NSW government review into smartphones in schools that they were useful for learning and educators should help students use them constructively.
