How many people are using WUaS? ... am seeking for many in collaborating with edX Online Campus beginning this January ... 

(Is Khan Academy too testing oriented? ... re the aversive experience of testing in today's online education, and even regarding BF Skinner's animal behaviorism, and re schedules of reinforcement. Who knows re engagement of students toward free-to-students' online degrees?, - and in thinking about World Univ and Sch).

World Univ & Sch's mission is as broad, - planning to code for 7.8 billion people on planet - at You at WUaS  - https://wiki.worlduniversityandschool.org/wiki/You_at_World_University ...

And you'll find World Univ & Sch's mission here - 

https://wiki.worlduniversityandschool.org/wiki/World_University_Foundation

Mission:

World University and School's mission is free education, courses, and degrees in all known languages. World University and School (http://worlduniversityandschool.org - like Wikipedia with best CC-4 OpenCourseWare) seeks also to facilitate all levels of teaching and learning through open, editable wikis. WUaS plans to accredit at the university and high school levels to offer online degrees and diplomas in all countries' main languages. WUaS’s wiki will involve open and editable teaching and learning but also non-editable courses prepared under a Creative Commons’ license. WUaS will facilitate the use of free CC courses as credits toward degrees. Due to the rapid spread of broadband worldwide, WUaS plans to make this accessible to underserved parts of the world and to poor people everywhere. WUaS will explore the possibility of using universal translators to extend the project automatically to any language with time.
