Education/Collaboratively generated educational material
Educational material can be created and edited collaboratively, constantly evolving and increasing in both quantity and quality, similar to the evolution of the famous wikipedia

- Wikiversity
- WikiEducator - dedicated to building a complete education curriculum by 2015
- ck12, free, flexible textbooks for the whole American educational syllabus
