My wife has been teaching her students online since the lockdown. She can share a whiteboard, notes, assessments. The students love it. First, they don't need to travel 30 min to school in the morning but secondly, they feel more focused during the lessons. We will need to ask ourselves as a society whether we shouldn't do more remote going forwards.
They do need to do lab work and practical exercises where they need to come to school. Also, we all need real social interaction.
Perhaps school facilities could be shared by more students if the lessons were staggered so not all students came to school every day but some worked remotely on certain days.
We have to ask ourselves, will life ever be the same again after corona?
