The biggest advantage that I see is that games engage students. This is not an "every student" situation, but most students in middle school become engaged through games. The idea of putting engagement before content in education (Prensky, 2005) resonates with me when thinking of digital games in learning. I can stand in front of students and discuss the amazing world of sentence fragments with them or give them the opportunity to try a game like Floyd Danger Adventure to recognize complete sentences and fragments. When I was a student a concept like this was taught with worksheets and practice. Now I can show them the concept and have them practice with a game.
Another terrific advantage that games bring to learning is collaboration.
On page 179 in Roblyer and Hughes, they point out the Tsekeleves et al. study which identified prominent benefits for learning from the inclusion of collaboration in both immersive and realistic setting using problem-based learning. Students love to work in groups or with a partner in the classroom. Games give them an opportunity to solve problems together and learn in a social setting that they crave.
Students often learn through shared experience. When students are all playing the same game, you can hear the conversation as they share what happened or how they did or any number of other details from the time spent at the keyboard.
Digital games can offer an instructor an amazing tool when working to engage students in the classroom. The games also offer an amazing tool to allow for student collaboration and shared experiences in the classroom. On top of all of that, games are just plain fun for students.
