A couple of books I've found helpful:
The Well-Trained Mind
Amazon.com: NEA: Trojan Horse in American...
There is another book - can't remember the title, but it goes in depth into how American education was hijacked by the radical left (Dewey etc), and exposes the mindset and thinking behind modern 'education'. It's interesting that the Democratics are so opposed to home schooling - of course they are, they want to produce citizens of the state, brainwashed by cultural marxism; the last thing they need is having people like Christians actually teach their children at home, instilling into them religious beliefs and a sense of pride in their history - how dare they! And what! children knowing their grammar, and learning things like logic and Latin? They certainly won't grow up to vote democrat, that's for sure.
