Half of highschool courses on line by 2019

Half of High School Classes Could Be Online by 2019

Low-cost delivery and tailored learning opportunities could drive up to
half of all high school courses online by 2019, according to a report from
researchers that's set to appear in the summer issue of Education Next,
published out of the Hoover Institution, the public policy research center
at Stanford University

As other predictions, this one too seems a stretch, but one can see that online education may become more attractive.
