I know Elisabeth Jean and Gabriel Maynard have used it with elementary and middle school with some good results.

Not only is this a great visual effect to motivate students but also it keeps a record or their progress during the semester and could be helpful to learnign specialist or even to the parents to see how the student is performing.
