One of my friends has a 16-year-old boy who is in Advanced Placement in high school. Not surprisingly, all those not in Advanced Placement speak Spanish. TF, who is a history buff, went through his son's history text, expecting to tear it apart. He didn't have to, finding it an excellent book.
On the other hand, the one for the Spanish speakers was so bad TF went to the principal.
One of the things he complained about was that the textbook was writtn by a Jew, and listed how many Jews died in every country in Europe during WWII. This is not American history, it is European history, and has no place in American textbooks.
Worse, the book did not list how many Americans died in WWII. WWI, and the War between the States. Just how many Jews died in Europe.
The principal, who has a Ph.D in Pyschology (worthless) knew nothing about the textbook. He also said that TF was the first parent ever to complain about the quality of the textbooks.
Parents should pay more attention to the crap being shoveled into their kid's heads by the public schools.
