Virtual schooling has really come a long way.   It used to be nothing more than distance education through a school like BYU Independent Study (http://ce.byu.edu/is/site/ ).  Then it moved on to more active approaches like recorded audio and things like that.  Now there are places like Fieldstone Academy (http://www.fieldstoneacademy.org/virtual ) that have fully live classes.  The student sits at home and sees the teacher teaching live.  There’s also a lot happening with online tutoring and things like that.
