Later on that same day and over lunch with a friend, our conversation explored the health concerns developing over the effects of wifi signals on the human body. It would seem that the jury is out on this one according to Health Canada. If school administrators are worried about the effects of the wifi networks on teachers and students, they should first begin by warning about cell phone use. (The radio frequency exposure from wifi is less than 1% as compared to a cell phone.)
Wouldn't it be great if teachers had a device that rendered student learning visible? Wait, I think it's called authentic assessment. Thoughts for another day.
