A relative of mine, Substitute-teacher (usually inner city), brings a "mesh pocket shoe hanger" to each classroom. During roll call, each kid must show the phone is off, and she hand writes (in cursive) the child's name on a piece of masking tape across the screen and back, while noting which kids phone was put in which pocket. The kids are allowed to have their phone back at the dismissal bell, and not a second earlier. She allows the kids to send a text to their parents letting them know their phone will be off for the day, and if an email list is provided, also informs parents that any emergencies should be directed at her phone or the school office. Obviously this creates quite a reputation with kids and school administrators... but what is a surprising is the occasional protest from parents wanting to talk to their kids all day. Her stance is "take it or leave it, I'm not changing", and she doesn't always get invited back by certain schools.
