Rosetta Stone: A Natural Choice

Rosetta Stone is a natural choice for many language revitalization programs because it helps users develop everyday proficiency naturally, the same way people learn their first language -- by associating new words with real-life meaning. Rosetta Stone's Dynamic Immersion(TM) method uses thousands of real-life color images to convey the meaning of the spoken and written phrases in the program. Its carefully sequenced structure, use of native speakers and ability to provide instantaneous feedback teaches new language without memorization, translation or grammar drills. In the program, Kanien'keha words are never equated to English words, ensuring that words don't lose the many aspects of their meaning in the teaching process.

I wonder if "Rosetta Stoned" has anything to do with this. In the beginning of the song, the words are very unclear... later on they become more understandable after being distorted with effects. When Maynard talks about not finding his pen, It might relate to new language being taught without memorization... maybe.

"'We believe the best way to preserve a language is through teaching and learning, keeping it a living language in the hands of the people to whom it belongs," says Ilse Ackerman, manager of the Endangered Language Program at Rosetta Stone. '

A Language Nearly Lost

Between 1892 and 1969, thousands of Aboriginal children in Canada, including many Kanien'kehaka children, were not allowed to speak their native language. As part of Canada's government policies, Aboriginal children were forced to attend residential schools where only English was allowed."

I remember Maynard making a reference to Aboriginal people/religions during an interview regarding "Lateralus."
