That is an interesting observation and adjustment you have made. I have always used a strict no cell phone in class policy and have also found myself relaxing that policy during this term when I taught a class in a classroom not only without computers for the students, but with the instructor computer not working. I was not even able to pull up information on my computer and overhead projector to share with them. I gave an activity in class and found that they were searching information on their phones also, but the interesting thing was that they were locating information and making progress on the assignment. So I am in the same boat as you - thanks for sharing!
