I took a day off last week and was unavailable to do an interview with a student who was working on her science Challenge Based Learning project. Fortunately, I could still help her out with the voice memo feature of my iPhone. She emailed me questions, and I emailed audio answers.
None of this is rocket science of course. The kids consider this perfectly ordinary. But it's kind of "out there" for and old-fogie administrator. And I have found that snapping pictures is a very social business around school, and gives me a pleasant way to interact with the kids when I am making the rounds.
In a 1:1 iPad school, the possibilities are marvelous for a classroom teacher, particularly with all students armed with an HD video camera. Though our laptops were outfitted with cameras and mics, they were larger, heavier and much more awkward for snap and shoot activities.
I admit the usages I have described are pretty prosaic, but they have made my job more interesting and fun. If others at school have the same experience, that can't be a bad thing.
