Good article. I had spent some time working as volunteer at a Title 1 school and they had iPads in most of the classes. I thought it was interesting that in a school that has kids from low income families that a lot of the schoolwork was done with technology, considering that many of them have the same struggles as mentioned in this article.
I don't think we should have students just playing games all the time, but they can be a good arrow in the quiver of teaching methodologies. This is an interesting article into the use of games to teach core subjects, like science.
