All three of the following books are referenced in the movie IndoctriNation and are free to read on-line.
This week, my husband and I started reading John Taylor Gatto's book An Underground History of American Education. Having worked within the walls of the public schools as a high school and middle school math teacher, I can totally identify with what is written in this book. Read it for free at http://www.johntaylorgatto.com/underground/toc1.htm.
If you have about an hour to read a short book, a pdf version of Murray Rothbard's Education: Free & Compulsory can be downloaded at http://www.mises.org/document/2689/Education-Free-and-Compulsory.
And another book you might want to read, The Deliberate Dumbing Down of America, is available as a free pdf download at http://www.deliberatedumbingdown.com/index.html.
Thanks to Tami for recommending these books!
And, finally, don't forget to read Leigh Bortins's book Echo in Celebration: A Call to Home-Centered Education - a short, easy, and inspirational read. I highly recommend it! Download the pdf version at http://www.classicalconversations.com/pdffiles/EchoACallToHomeCentMar2008.pdf.
