In the 20th century, student work was dominated by paper-print assignments, particularly essays. This was a reflection of the dominant media technology of that century--books, magazines, newspapers, radio, and television. But those days are gone. In the 21st century, the dominant media technology of today's students is the Internet. In addition to being one of the most popular video game genres (along with adventure and sports), RPGs (Role-Playing Games) are perhaps the most appropriate video game genre for educational purposes. Oregon Trail, where students take the role of 19th century pioneers in the American west, is one early example of an educational RPG (originally played via a CD on a computer). There are currently more than 25 million people worldwide playing RPGs online. This article lists some of the most popular MMORPGs (Massively Multiplayer Online Role-Playing Games) and discusses four potential barriers to the transformation of student work from paper-print essays to educational RPG websites--skills, costs, theory, and assessment.
