It provides real-World experience to student translators
The result is contributed to a major Open Source project
Remember all the homework you did in school? Well, it never was useful to anybody!
Students learn a software which that has a high likelihood of being useful to them (ex.: for a personal blog, a class wiki, etc.)
It is repeatable to any number of languages
Once we have ironed out the process, any translation department in the World can participate!

Other notes
Sometimes, the feature / label is not clear in English, making it difficult to translate. We should develop a way for translators to report unclear interfaces.
Untranslated strings should have a different style (ex.: be in red) to make it faster to find them on the page and to avoid ambiguous cases where the translated word is identical to the source (as often happens between English & French)
We would need to be able to track who translated what (via tiki.org usernames) so the teachers can evaluate students and for proper credits to be attributed when the bot commits.
