Textbook Stories...

Environmental law professor Jonathan Adler writes in the Washington Post about Environmental history errors in a high school textbook - The Washington Post
The other night I took a look at a few pages in my daughter’s U.S. History textbook (Pearson Prentice-Hall, U.S. History: Reconstruction to the Present (Ohio Edition, 2008)) concerning the growth of the environmental movement in the 1960s and 1970s, as I was curious what my daughter was learning about it. I expected to disagree with some of book’s choice of emphasis or the way certain events are portrayed. What I did not expect, however, was to find a series of plain factual errors....
I'm reminded of experiences 20 years ago with my children's textbooks. I still have a letter (well, I still have the TeX file from which the letter was printed) from March 4, 1995, noting that page 197 of my 10-year-old son's science book, by Mallinson et al., defined "resistance" as "a force applied by a machine". That's the meaning of "resistance"? I added that
The Mallinson usage seems clearly counter to the ordinary English use of the word, as well as to that of traditional physics. I suspect a typographical error here, but there's no diagram, example, or calculation given which might clarify their meaning. That, I think, is a more serious problem than an erroneous definition, and I'd noticed it before with this book....
It's not really fair to say that the book was wrong, because the book didn't really mean anything by its definition....it was just words. The book was not even wrong. It's a problem noted by Richard Feynman in his fairly famous encounter with the California school textbook system, some thirty years earlier, emotionally described at Corruption in textbook-adoption proceedings: 'Judging Books by Their Covers'. This has been going on for a long time. Some people don't want to allow Wikipedia as a reference, because it does have errors. Many of them. Perhaps we shouldn't allow K-12 textbooks as references either.

One World Schoolhouse

The Slate.com version is Salman Khan and YouTube...
Once upon a time, a brainy MIT graduate working as a hedge-fund analyst started tutoring his cousin in math and science online. He decided to make YouTube videos of his tutorials. The videos racked up millions of views and reached audiences around the world, and appreciative students offered stirring testimonials. After three years, the hedge-fund analyst quit his day job to set up an educational nonprofit called The Khan Academy. The mission: provide a world-class education to anyone, anywhere for free.
And he has a new book, The One World Schoolhouse: Education Reimagined: Salman Khan. Downloading....
Or then again, maybe not.

Open Textbooks

If I were in charge, there'd be a lot of this going on... Teachers Write an Open Textbook In a Weekend Hackathon
"A group of Finnish mathematics researchers, teachers and students write an upper secondary mathematics textbook in a three-day booksprint. The event started on Friday 28th September at 9:00 (GMT+3) and the book will be (hopefully) ready on Sunday evening. The book is written in Finnish. The result — LaTeX source code and the PDF — is published with open CC-BY-license. As far as the authors know, this is the first time a course textbook is written in three-day hackathon. The hackathon approach has been used earlier mainly for coding open source software and writing manuals for open source software. The progress can be followed by visiting the repository at GitHub or the project Facebook page."
Free information-resources for education ought to be something everybody could get behind...
