Enrollment in online classes last year reached the 1 million mark, growing 22 times the level seen in 2000, according to the North American Council for Online Learning. That's just the start, says a new paper by the Hoover Institute, a conservative think tank at Stanford University. Its authors predict that by 2019 half of courses in Grades 9 to 12 will be delivered online. The efficiency of online learning accounts for this growth. But there's little research assessing the quality of these programs, which some experts say don't have enough official oversight.
Obviously online course content delivery is coming soon, but "half" of all courses by 2019? Part of me says that's actually low. I think more than half will be offered a lot sooner.
