I spent nearly the last decade teaching high school math in public schools in the US and this is my attitude as well. Most of your intended users are adversarial; most students enter the classroom not wanting to learn most of the subjects they are required to. The district I worked in the longest had one laptop per student at the secondary level and we tried lots of different products. What I saw with my students was that those few who were self-motivated would be successful and those that were not motivated would just drag along, no matter how much interaction and gamification was involved. So the outcome was the same as if you just gave them textbooks, except that textbooks don't have the web to distract users.
