> whether the digitalization of classrooms had been evidence-based

There is no indication that the current opposite move is evidence-based either, so it's basically your typical vibe shifts. Might revert back to "digital basics" in another decade or so with identical quotes?

Usually you have to prove the effect of introducing something new.

which, in this case, is a paper book

Seems strange to me, a bit like the evidence required for new foodstuffs without judging the old ones by the same criteria. People have been winging it and now new options would have to be scrutinized before use whereas the old 'wisdom' can just stay in place?

Then again, by comparing new techniques against old ones, presumably the old ones get studied indirectly as well. Guess the glass could be half full with this approach
