Dad was a science teacher. He told me that 10% of his students were going to learn, whether or not he actually did any teaching. Contrarywise, 10% weren't going to learn, no matter what he did. He pointed out the material to the top 10%, kept the bottom 10% from bothering other students, and did his best to explain the lessons to the 80% in the middle.
The self starters will do fine with distance learning. The losers are actually easier to deal with when distance learning, as they have less ability to cause trouble. However, the children that can learn but have a few problems are much harder to help and have more distractions with distance learning. In person, a teacher can see the blank looks and modify their presentation accordingly, that's a lot harder to do when you have little faces (or more often just a blank spot with an identifier) to go on. Minimal feedback = poor outcome, in classroom or electronic circuit.
A teacher I know does special needs kids. Her students were utterly unable to handle distance learning, and have regressed for the most part. It's hard enough for her to get progress in person, doing it long distance was simply impossible.
