Open source is gaining importance for schools. The growth rate is a healthy 70% per year. Beyond Linux and the well-known Indiana open-source initiative, a number of other states and districts are considering open source. Moodle, a curriculum delivery platform, is an example of a popular open-source program. Widespread open-source usage will grow eight-fold from 2006 to 2011.
Wow. I'm hopeful that increased open source will spawn fewer Microsoft-bred atrocities like this:
Only kidding! Actually, the salient quotes from the report noted above have to do with K-12's use of open source to manage school systems, and not with how kids are taught. Miss Teen USA (South Carolina) would know just as little about US geography under open source as under her current diet of Microsoft Office and Google.
Humor aside, it's not very hard to figure out why the Education market would be a big win for open source: K-12 budgets are small and open source fits right into them. They can't afford to waste money on licenses - they need the subscription model that only requires them to pay for value, not licenses.
