One CW blogger and history teacher has noted he no longer uses textbooks in his classroom; suggesting they're of little use. I would add that homeschooling, coupled with technology, is making the traditional classroom obsolete. Though I don't necessarily recommend this curriculum, here's one more option for parents who wish to teach from home, but feel they need some additional structure. This could lead to a reduction in costs for localities should more parents take advantage of the "virtual" classroom: less buildings & less administration all equal a reduction in costs. Of course, you can expect the teacher's unions to rant and rave about losing positions and power.
