Total waste of money imo. A friend who is a teacher says it's pointless as they still have to use pen and paper in the exams, so they obviously need to be used to doing their work without tech for their GCSEs etc
Well, several private schools near me use tech (ipads etc) daily and seem to get fabulous results.
I wouldn't be too quick to dismiss it. Obviously if youve got kids who don't take care of them, and parents who think its a load if bollocks then it's not going to work.
I had the same reservations re exams and writing but then i realised that was a bit stupid. I spend all my time on screens ans haven't lost the ability to use a pen.
