"The path of technology integration in education is lined with disruptions on one side and opportunities on the other. Technology teams work to bring useful technology into teaching, all with good intentions, only to encounter unwanted side effects such as distraction and disruption in the classroom."
It's important or me to add an editorial note here: I don't believe that technology ADDS a distraction to the learning environment. Students are engaged in the learning or they are distracted. When they are distracted, the technology is just another vehicle for the distraction—no better or worse than daydreaming or acting out.
