High school could be moved to an online basis.
Consider a hybrid.
Some classes could be large in front of a screen.
Some could be mid-sized. Some could be small.
Some could be at home, individualized.
The internet allows for this mix for “lectures”.
Mid-sized and small groups are best for “discussion and questions”. Teacher assistants would staff both large, mid-sized and small groups. Many times this is better than individualized when the students family setup is less than ideal.
Bottom line: We need public schools and school boards to experiment with a variety of situations. It might be that what works in one place does not work in another.
Abolish the Federal Department of Education and its ability to steer everyone into one-size-fits-all
