"...games and repurposed game technology, collectively called "serious games," have yet to be fully embraced by educators. It's not enough to declare that "games teach" and leave it at that. Teachers aren't going to hand out a game to a bunch of students and simply trust that the students have learned the material. Serious games, like every other tool of education, must be able to show that the necessary learning has occurred. Specifically, games that teach also need to be games that test. Fortunately, serious games can build on both the long history of traditional assessment methods and the interactive nature of video games to provide testing and proof of learning."
