Parents do care about improving learning. I certainly see better outcomes for my kids with book based learning. Mainly because the screen based equivalents have such bad ergonomics at the moment. E-learning "tools" that schools choose seem to be abysmally bad.

For the rest: yeah there's nothing more entrenched than the mindset of the people that run schools. They conceive of their school as the epicentre of all problems and solutions with respect to kids education. They cannot imagine they might be simply irrelevant on some issues.
