It's been the case since the iPad 1 came out. Perhaps it'll change in the future, but this really shouldn't be of surprise to anyone.
Tablets make it easy to consume, but do not fool yourself into thinking that's all they can do. My iPad Pro is more capable than the laptop I owned two years ago, and costs less as well.
My company is responsible for a number of different school districts, and I've seen this happen at all of them, despite them being warned about the outcome beforehand.
Over the last 18-24 months the classrooms have been introducing Google Docs and Chromebooks. Now the district is purchasing a mess of Chromebooks on their own. Every kid has been given their own gApps account. The iPads are going to gather dust, as far as I can tell.
I can totally understand why. The laptops are way more functional for what the kids are doing in the classroom. iOS is (finally) catching up to the needs of education with things like the multiple-login enable, but it's too little too late.
A lot of parents, myself included, are extremely pissed off at the moment. Maybe we should get in on this.
Middle and high school kids use chromebooks instead. Works out fine.
Should not be surprising or controversial that there are appropriate and inappropriate uses for technology.
For high school students, the iPad Pro is great in art class. Again not surprising.
