We homeschool, even though hubby has been a public high school teacher for 37 years. He'll be retiring in 2 years, if he can hold out that long. He teaches US and world history. The school district has dumbed down the books over the years like you would not believe. The current world history book devotes 70 pages to anything prior to 1600 and 500 pages for everything after. There are more words devoted to the attire of Louis XIV than there are to the Reformation. The US history book is just as bad. It is called something like The Americans ... From Reconstruction to Today. 10% of the book devoted to Civil War and before; 90% to Reconstruction and forward.

It was ugly, and in the end, she got her A.
