Does this qualify?
It does take a bit of time to explore the potential, but well worth the effort, to get the best out of it. You'd have to see the children's faces to believe it. I like the fact that it produces an interactive element to so many of the things we do ordinarily. What we are doing now in our classrooms with these new tools is yet to be measured, but I am sure someone somewhere will try to measure, and that frightens me as a creative person, as confirmed by yesterday's INSET.
