Texas officials say nearly 400 of the state's 1,200 school districts are using a geography textbook that refers to slaves brought to America as "workers."
Houston mother Roni Dean-Burren said Monday she struggles to understand how that description was approved in her 15-year-old son's textbook. She posted her disbelief on social media last week. An ensuing uproar led the publisher to change the wording.
McGraw-Hill Education is one of the biggest textbook publishers in the U.S.
It posted a Facebook message saying the company "can do better" and promised immediate revisions to digital copies. However, the textbook still remains in classrooms.
The Texas State Board of Education approved the book last year. The wording went unnoticed by opponents of the socially conservative board.
