Israeli universities don't usually use textbooks, partly because Israelis go to university after their mandatory army service. Some students are already married with kids and can't afford to buy textbooks. Every course has an official textbook, which the school has copies of. The system works because (at least at my university) all lectures and recitations videos are available online. Good luck doing that in K-12.
