Ubermix is extensively used in schools. The system was designed to store user data and software in seperate partitions. So, in case the computer malfunctions, the user can wipe out the operating system and resotre fresh copies quickly. From Ubermix founder, Jim Klein, in an Opensource.com interview:
Ubermix comes pre-loaded with a number of applications for education, productivity, design, programming, Internet, and multimedia construction. Education oriented applications like Celestia, Stellarium, Scratch, VirtualLab Microscope, Geogebra, iGNUit, and Klavaro, as well as educational games like TuxMath, TuxTyping, gMult, and Numpty Physics all bring with them plenty of opportunities to learn.
Internet applications we all know and love, like Firefox, Thunderbird, Chrome, Google Earth, and Skype are all there. Common productivity apps like LibreOffice, NitroTasks, Planner Project Management, VYM (View Your Mind), and Zim Desktop Wiki are too. Kids interested in design will find the GIMP, Inkscape, Scribus, Dia, Agave, and even TuxPaint for the younger ones. And apps like Audacity, Openshot, Pencil, and ffDiaporama help round out the media offerings. These, and many more, make Ubermix a powerful launchpad for student creativity and learning.

From Sugar Labs:
Information is about nouns; learning is about verbs. The Sugar interface, in its departure from the desktop metaphor for computing, is the first serious attempt to create a user interface that is based on both cognitive and social constructivism: learners should engage in authentic exploration and collaboration. It is based on three very simple principles about what makes us human.
