Reflections on "How to use Cell Phones as Learning Tools"

I liked the idea of students working in groups to eliminate the need for all students to have a cell phone.  I want to try having students audio or video record an explanation to a problem.  I could have two students work together to do this and alternate who does the explaining or have both do part of the explanation, even though one student has the phone in hand.
