NSW public high school students are the latest to cop a ban on mobile phones at school, with the new rule coming into play today. Premier Chris Minns called the step “necessary” to address the risk of declining results and up social interaction in the playground. NSW isn’t the first to make the move – there is already a ban in Victoria, and South Oz will join in when term 4 kicks off next week. Western Oz and Tassie have ‘off and away all day’ policies, and Queensland says it’s looking into it. But the experts say there are few educational benefits from a ban. Child psychologist Dr Michael Carr-Gregg disagrees, saying it’s more about anxious adults… “As far as the helicopter parents are concerned – they will have to learn how to call the school office, and their children will benefit from having some independence,” he said.
