> If you can't bring enough material into the building within books and teacher's brains to teach, you're terrible and pointless. The numbers are smaller and smaller, but there will still be kids whose only access to the internet is their parents' smartphones. When I personally mentored a couple of pretty bright high school student interns, one of whom scored above 1500 SATs and a 36 ACT, they both found it really helpful to look at Khan Academy / YouTube clips to better understand what I was explaining. If the poorer kids don't have access to these explanatory videos, except when their parents are done with their phones, they will fall further behind than they otherwise would have. Perhaps a compromise would be to limit internet access to the school library?
