A local tech school I work with the teacher does attendance by the phones. They are to be put in a cabinet in a small bin. If they are not there...the kids do not get listed as being in class. Yes...There are a couple kids with no phone...but sadly only a couple. I personally think this is the way to handle this. In this class's case it is a machining/manufacturing program it is especially important to have the kids paying attention due to safety issues. They are quite literally running machines that can kill people. When I was young we were told to not bring anything that was a potential distraction from learning...for me or others. If we did, it was taken away. This also applied to hair and dress code...not that I am against free expression or anything like that...but the point was that anything that took away from the educational process (again...of you or others) was not allowed. I remember kids being sent home for wearing inappropriate Tshirts or haircuts (dyed mohawk). This was not the 50s...this was the 80s-90s. Not sure what changed...but in my case it is time as a parent to make an effort. There is no reason for my kids to have phones at school...They don't answer when I need them to anyways.
