Story highlights A McGraw-Hill "World Geography" textbook calls slaves "workers"

A Houston-area mother complained about the language to the publisher

McGraw-Hill will change the wording in future printings

(CNN) Textbook publisher McGraw-Hill will rewrite a section in one of its books after a Houston-area mother complained that it whitewashes the role of slavery in bringing Africans to America.

Roni Dean-Burren took to Facebook last week to vent her frustration over the wording of a passage in her son's "World Geography" textbook that calls African slaves "workers" and "immigrants."

"The Atlantic slave trade brought millions of workers ... notice the nuanced language there. Workers implies wages ... yes?" she wrote.

Dean-Burren's post gathered a lot of attention; a subsequent video sparked spirited feedback and had drawn 1.4 million page views on Facebook as of Sunday.
