Would you allow (or prefer) your children to educate themselves online before/after high school?My oldest son is about to be a senior (twelfth grader) in an online high school. We were just online for the school's orientation to this school year. He was a member of the founding class there, so we have a LOT of ideas about the trade-offs in online education.
One way he gains satisfaction for his social drive is by taking most of his eleventh grade and twelfth grade classes as a dual enrollment student at our friendly state flagship university. The university offers courses that would be quite impracticable to offer online.
He is looking forward to a RESIDENTIAL college experience, where he has much face-to-face interaction with classmates throughout all hours of each week. Neither he nor I would consider an online college environment--that would be missing out on too much. Please note as a response to the premise of your question above that some students attend some colleges at HUGE discounts from list price, and at some highly endowed colleges list price for any student is still less than the actual expenditure per student on instruction.
Is anyone here working on an online education technology? Website?
I am. It's very early stage, so I can't describe it with exactitude (because we are still making up our delivery model), but the idea is to scale up my current face-to-face math teaching and build a community among learners who can't travel to my town for the community I'm already building up with my in-person classes.
Life is all about trade-offs. Some trade-offs fit one learner, and some another.
