It seems so obvious there ought to have been a rule a long time ago. Take away cell phones from kids while they are in class so the teacher can drill a little knowledge into them. That’s what Northern Secondary School teacher Shahnaz Khan is asking in a letter to area parents. Khan says what every sensible mother and father must know already. Cell phones distract teens and adults too, frequently when they are supposed to be paying attention to something else — something important. Ms. Khan is an English teacher at NSS. She tells the CBC that she has had to adapt as students increasingly come to class tethered to handheld screens. And while the devices are sometimes used as part of the learning experience, very often they simply distract — both the students using them and others in the room. It is an entirely reasonable idea. The need to ask is a sign of how dizzy society has become that it is even open to question. In recent years we have seen lawsuits launched by parents who wanted to prevent breath tests for students entering the Spring Prom. The right to go to a school event intoxicated.
