To the editor: Teachers aren't glossing over history

As an American history teacher, retired after 35 years, I am mystified by several recent letters to the editor. The letter writers seem to be laboring under the impression that over the past few decades Ohio teachers have ignored, or, at the very least glossed over, the study of slavery, its origins in this country, the Civil War, Reconstruction, the rise of racist groups such as the Ku Klux Klan, and the civil rights movement.
