Fifty-nine percent of private campus respondents to a recent survey said “greater faculty time and effort” was a central barrier to a more thorough embrace of online education, with 27 percent of responding institutions saying they had overcome this obstacle.

Half of public universities now offer five or more fully online programs, the report said. Only 15 percent of private universities have reached that level of online learning.
