From a teacher's perspective, I'm sure the craft is a mess of bad school policies vs. so-called "best practices" vs. real learning science vs. government policies vs. ancient bad advice (eg. learning styles and tablets in classrooms) vs. personal opinion.

It's not like there is a senior engineer who's got mountains of expertise to defer to (like a software team would have). Teachers are likely given directives from their schools and get dumped a bunch of tablets and are told this is "modern" education and to just roll it out.

Anyway, to your point - top-down directives are what change schools. There has been success such as banning smartphones in Ireland & UK recently. Schools taking on the problems and then solving it themselves could go a long way, rather than waiting for government to mandate things.
