I agreed with basically everything that was said in the article, although I think that there are other circumstances that can prevent kids from learning through the gaming method. For example, if the student is often absent, the game might become uninteresting to the child, especially if all the classmates are far ahead. After all, that competition between the peers is another drive that keeps the children motivated. That can work against them as well if the student who doesn’t have a many points feels like he or she is loosing the race, even if the game isn’t too hard at the moment.
But without considering these things, it’s a very useful method of teaching, especially in ESL classrooms. As a volunteer in one of such classrooms, I see how eager kids are to play it. The teacher has a record of their activities, and an analysis of how they are doing, especially the recordings that the kids make when they read the story out loud into the mic. Another thing that the teacher does is other activities with the kids, especially the ones that are more behind in their “gaming” process.
