That's not true. My district told parents it would lighten backpacks. They eliminated lockers. Now kids have to carry backpacks full of textbooks, AND their iPads, AND be responsible for both electronic work and paper work.
Root cause: ebooks too expensive, schools were subject to the same racket as any student: rent-seeking publishers.
MIT's probability course is amazing. So it can be done, for a given audience at least.
I have my doubts about a computer convincing someone who lacks confidence that they are easily smart enough to excel at this task or learning in general.
What do you use a screen for? YMMV. If they're ever going to work in a school some teachers are going to be doing amazing things to make that happen. How would they know what to do? Easy to see good teachers failing at that too.
Then again, I'm a cynic.
