I'm not sure presential learning works very well these days.
It really depends on the teacher. Some can not adapt and become horrible teachers (quality-wise). They feel they lost grip of the class (no visual feedback of a child not understanding, by reading the face of the child and knowing immediately to slowdown, backtrace. Instead we save bandwidth by disabling video); some get locked out of their own zoom, that kind of stuff happens to technophobes. And teachers get depressed too.
Some do adapt, and they are very good at it.
Thas is a manual overhead projector thing. Would a math teacher get those 200 dollar digital overhead projectors from the school board? Of course not! Schools complain even though they save in heating/cooling costs. Cleaning the school is faster.

Some actually wait passively to get the tools from the school in order to teach... which never come because the board is blind, stupid or both.
Others just explain once, and expect the explanation to the "slow learners" to be done by the parents as "answering too many questions" is tedious.
Truth is, teachers have a curriculum to teach (each year the same). And the speed at which they need to teach does not leave much time for other things. By cramming so much stuff, you can not go in-depth. And can not lose focus either.
So in chemistry, where they teach metals with electron orbits and thus it's a small sidestep to teach NPN transistors... well they don't. No time.
Being a PE(*physical education) teacher means you basically get to do aerobics, because you have to use things ALL the kids in class have (usually by saying: next class, have such and such (cushion, paperball wrapped in aluminum, spoon,etc ) ready). And you can't assume anything about the floor could be dangerous marble, or carpet where you can't use tape to mark areas.
And the school blames the government for putting more "important" things in the curriculum, and the books need to get re-printed with the new material, and then you can't buy your books second hand because you miss that new chapter (also applies to a digital copy).
And in order to make this larger curriculum fit in a school year, they need to pluck out things. Like a jenga tower. Ministry of education puts blocks on top, school needs to remove blocks below (but not the new blocks, those are "important", like LGBTQX classes, so they drop Schopenhauer and other well rounded philosophers to make room for it).
In my case they dropped the pre-war. The part where you learn to detect that "uncomfortable" feeling you get just before war breaks out. To learn the signs leading up to conflict... in favor of modern industrialization (sure, sure, also important, but so dated and not applicable to today because the rules changed quickly, very quickly. All that industry collapsed or we got saturated markets, where dynamics is different, not based on growth only)
sorry for the long rant.
