Democratizing education? Examining access and usage patterns in massive open online courses, 1245- ["These patterns extend into the era of free Web tools as well. Reich and colleagues examined the use of freely available wikis--platforms for collaborative Web publishing--in U.S. kindergarten to high school (K-12) schools in the late '00s (12).

In schools serving low-income students, wikis were more likely to be used for teacher-centered content delivery.
