... my wife is a teacher and her high school decided all teachers must have and use iPads. She teaches horticulture and the apps in the Apple store are all for preschoolers, maybe grade 3 max. She found one or two BBC interactive documentaries with David Attenborough but that's it. Everything else is babysitting software.
Almost (not total) waste of money, and they're laying off teachers because they don't have enough funds.
Training for the iPads? Two two-hour sessions for the staff. That's it.
I second the thoughts by others that this is a bad way to spend all-too-sparse funds in the educational system.
