Now is a very good time to try to transition systems over to IT based and allow the students to learn and test from home under family supervision.
If successful I can see that the system may change forever with a total rethink about the necessity of ever going back to the traditional system.
There will still be teachers, but simply teaching in a different way. The need for huge and expensive school buildings can perhaps be reduced significantly.
A down side is the loss of direct face to face social interaction, especially in primary years, but also in secondary. Another is that some parents may not give a hoot and their child's education would stop.

Any thoughts?
