The parent controls on devices is terrible. Android won't let me block hotspot at all (which they have turned on so their can use their school device after I turn the router off for the night). I can limit a game to only 5 minutes - but they have a dozen games like and that is an hour between them all (both not enough to really get into the game, and way too much time when they really do need a study break). I can block youtube, but if there is an educational video they need I have to unblock everything not just that one (or a limited selection). There are new play a game websites popping up daily, and when they to every kid in school is playing until we block it (or more likely the school blocks it as they are all playing in class on the school device) - but trying to block all but a whitelisted set of websites is no better since there are so many legitimate ones teachers really do need kids to see.
When you read the above remember not only do I need a solution it needs to be one I can figure out. My degree is human-computer interaction and I'm not sure I can design something I as an expert could make work - but I still need something.
Again, this problem is not new. However parents are still mad about the situation and governments who don't really have any better ideas see a need to solve it.
