"Moving Learning Games Forward: Obstacles, Opportunities, and Openness," by Eric Klopfer, Scot Osterweil, and Katie Salen of the Education Arcade, an MIT research division that explores games that promote learning through play, explains why educational games have seen an increase in popularity: mainly owing to the advances in consumer games.
A report from the Joan Ganz Cooney Center, "Game Changer: Investing in digital play to advance children's learning and health," claims that on an average day, children as young as eight spend as many hours engaged in media activity as they spend in school. Seventy-five percent of American children play computer and video games, it says.
