Seems I'm not alone in fighting incompetence and corruption in schools...:-)
Take a look at this article, and the comments from various people in various school boards in the U.S.
Our children are being denied the opportunity to learn about alternatives, and billions of tax dollars are being wasted. No wonder our schools don't have enough teachers, textbooks, lab equipment, etc., when we are sending millions upon millions to a convicted monopolist.
And it is getting worse in Canadian schools...recently, we've been required to use a MS only marks program, at a cost of $300 per license (even though intelligent schools are using the much better, much more flexible and FREE marks programs that are easily available). Oh, and that's $300 per school per YEAR. Yes, tens, if not hundreds of thousands of dollars wasted every year. Just for a marks program. And don't get me started on the tremendous waste of teacher's time this has created (and continues).
Want a concrete example of brain dead? The "Marks" program we are using will crash if the computer is not connected to a printer...that's right, hours upon hours were wasted as teacher's networked and standalone computers continually crashed if they were not connected to a printer. And the software is apparently written in Visual Basic (that's BEGINNER'S All purpose Symbolic Instruction Code). About as far from 'professional' as you can get...and it shows...again and again...sigh...
Your wasted tax dollars, not at work...

An excellent site for keeping track of how the world is changing to linux! :-)
Danish government IT is now offering linux.
And 50% of surveyed businesses are considering moving to linux! :-)

So, are your skills (and those of your students) going to be ready for the future? :-)
Linux deployments are expected to TRIPLE in the next 5 years or so!
(e.g. from a 12 billion dollar linux market in 2008, to a 35 billion dollar linux market in 2013...:-))

Why heck, it's expected to grow 21 percent, just this year, 2009, alone! :-)

Fire up that KDE/GNOME/XFCE GUI or cli today! :-)

And all 2,400 educational institutions in Tatarstan are changing completely to linux! (Find it on a map...)
And the better known government of Hungary, is now spending half of its IT budget on Open Source!

The world is changing...:-)

Seems the famous New York Times is encouraged by the rise of linux! :-)
