Sure, but there are all sorts of pendulum shifts in the teaching zeitgeist. Spaced repetition was just an app-based example: it's been a few years since I was in the classroom so I'm not sure what the flavour of the year is, but if spaced repetition were currently popular amongst schoolteachers, the swing away from it that I would expect to see would be to argue that memorisation isn't really learning and that learning experiences should be about developing deeper understanding, and so on. There is no measure of 'best practice'; a lot of these shifts are driven by personal preference.
