It cracks me up too how these technology-ignorant higher-ups think getting these kids touch-based tablets will somehow prepare them for highschool and college where they'll need to type papers, use excel, powerpoint, type out math formulas in various programs, etc, etc. Like knowing how to tap on everything is going to give them an advantage in the future. I've had a lot of words about this topic in general but it is/was one of the stupidest fucking wastes of money for the education system in recent years.
Like someone said in the other thread, the best option would have been to use less expensive devices, create an OS or school-specific content delivery system/manager, use/create programs that are specific to each grade and subject with a unifying background system between school for comparison and admin sake. This way kids wouldn't be using them for porn (by either circumventing the parental controls or having parents who don't give a shit) and off-topic games (during class mind you), and maybe not getting robbed for them or stolen as much if they weren't iPads.
I had to deal with this crap first-hand and it was about as nonsensical and frustrating as I could handle. Good luck in high school Bobby, you are a master candy crush player and quick alt-tabber (to switch programs and pretend to your teacher your actually on-task). I'm sure high school and any studying/hw using m/kb/practical application will be easy for you /s.
