Edubuntu a customized version of Ubuntu for educational use.
Edubuntu is a version of the Ubuntu operating system suitable for classroom use. As an educator you'll be able to set up a computer lab, or establish an online learning environment, in an hour or less -- then administer that environment without having to become a fully-fledged Linux geek.
Edubuntu is currently under development by the same development team that produces the wildly popular Ubuntu system.
Principal design goals of Edubuntu are centralized management of configuration, users, and processes, together with facilities for working collaboratively in a classroom setting. Equally important is the gathering together of the best available free software and digital materials for education.
The add-on CD contains additional useful packages, including many educational programs and all available language packs. It requires that an Ubuntu desktop system already be installed.
