North Dakota students may or may not learn about the first 100 years of America’s history. Important topics like the Declaration of Independence, the Revolutionary War and the framing of the U.S. Constitution may simply be ignored by teachers under new history standards approved by the state’s board of education last Monday, the Argus Leader reports. Current standards do not allow history teachers to delve into topics before the Civil War, so the new standards open up the door but don’t require teachers to cover early American history, as many would have preferred. The recently adopted history standards are set to take effect in 2016-17 school year and whittle the current standards from 117 pages to 44.
