Home schooling with computers is going to get better and better, while the public schools get worse and worse.
Public education is walking dead—it will just take a while before it collapses and all parents and kids are on their own.
Momentum is hard to stop—but eventually the corpse will hit the ground.
If parents and kids want to teach and learn in voluntary groups or families, fine.
If not, fine.
A reasonably smart student can use a combination of Khan Academy (free) and Brilliant.org ($120/year to access course content and problems) to get a well rounded understanding of math and science up to the sophomore college level. Throw in a workbook or two for rote practice of trig identities, integrals, etc. Add a home lab kit or two and a few field trips when necessary. And boom... you’re set for years.
