The Teacher Wars: A History of America's Most Embattled Profession

The first two thirds of this book was an interesting collection of basically snapshots through the ages (early 19th Century to 1970s). Then, it got (with a longish chapter) bogged down in recent disputes over teacher training and such. It didn't even really help me understand current disputes like "Common Core" and national standards that much. Not comprehensive, but a helpful look (supportive blurb by Chris Hayes suggests author's sentiments).
