Police-style body cameras are being worn by teachers in England to stop pupil disruption. Two schools are taking part in the pilot scheme, according to Tom Ellis, a criminal justice researcher from the University of Portsmouth. He says all teachers are wearing the cameras during a three-month trial period. He cannot name them, but told Newsbeat that both are “normal” state secondary schools. He says: “The teachers will be wearing the cameras very visibly, so there’s no attempt to be covert in any way. “The idea is that everyone is aware that the camera is there and is being used for a specific incident. “Where the teacher feels there’s a threat to themselves or to another student, then there will be evidence of that incident.” It seems that the cameras won’t be rolling constantly, with teachers told to switch them on whenever they want to record something. Mr Ellis says the scheme is not all focused on controlling bad behaviour. He suggests that teachers could ask permission to film positive events too. “This could help reduce reaction against them.” This comes as the Times Educational Supplement (TES) has surveyed 600 teachers about the body cameras. More than a third (37.7%) said they would wear them – and the main reason they gave was for gathering evidence of student behaviour. But that leaves 62.3% who were not so keen. Their main concerns were their own privacy, being spied on by management and privacy for the pupils.
