I came across a couple of interesting (and short) articles on gamification in education today. Although the language makes it seem like gamification is something only the K-12 sector is working on it is becoming a trend in post-secondary as well as job training. In fact, there are over five different seminars on gamification of courses at the upcoming Desire2Learn users conference.
The first article 25 Thing Teachers Should Know About Gamification, is a good introduction to gamification. There is also an interesting infographic here that gives a bit more detail on gamification, and an overview of the history of games in education.
