The Virginia Department of Education is reexamining the process it uses to select school textbooks after discovering that materials provided to the state’s schools by Five Ponds Press have numerous errors.

“In October, our state superintendent directed staff to conduct a thorough review on how we do this, how we vet textbooks,” said Charles Pyle, director of communications for the Virginia Board of Education. “We want to take a hard look at the process we use to develop the list that is presented to the state board of education about which books to include on the state adoption list.”

In the past, the state has tapped classroom teachers to review the books to determine if they are classroom-worthy. But officials are now considering requiring publishers to have high-ranking historians give their approval to books taught to students.

The books at the center of the controversy are “Our Virginia Past and Present,” and “Our America: To 1865.” The books claim 12 states joined the Confederacy rather than 11, Thomas Jefferson began his presidency in 1800 instead of 1801, the United States entered World War I in 1916 and not 1917, and thousands of African-Americans fought in the Confederate army, including two all-Black battalions under the direct leadership of Stonewall Jackson.

“I absolutely could not believe the number of mistakes—wrong dates and wrong facts everywhere,” Ronald Heinemann, a former history professor at Hampden-Sydney College, told the AP. “How in the world did these books get approved?

“This book should be withdrawn from the classroom immediately, or at least by the end of the year,” he added.

Pyle said that while the textbooks are in fact wrong, they are not the framework by which teachers create lesson plans. Instead, he said the state outlines the framework of the lesson plans and the textbooks are to be used as just one tool, and not the sole tool, for teaching.

“Our teachers are guided by the standards and the curriculum framework documents that we produce and those provide the roadmap and terrain for the presentation of the content,” Pyle said. “Teachers pull from a number of resources. We have so many cultural institutions, historical sites, museums, societies and so forth here in the commonwealth that produce teaching materials for Virginia studies that are fully aligned with the state’s standards.”

Pyle said it is unclear how many school districts used the textbooks, but he admitted that it was “quite a few.” A final ruling on the state’s plans is expected during the week of Jan. 10.
