Handheld Learning - learning with mobile and ubiquitous technologies

Plus side is that it will remove another non-"teachingandlearning" chore from the lesson management.  It will also give absolute certainty about when pupils come in (including who's late and by how much - as well as when teachers arrive at class late !), and when they leave the room (with or without permission).

Negative is that the routine of calling the lesson register and making eye contact (at least once in the lesson) with each pupil will be lost, thus making it much more difficult to rapidly learn their name - loss of the personal touch (but it could be replaced by something else, including "I'm doing my own register, kids,  in case the auto-system fails !).  Of course it could be linked to a monitor display over the door that shows the name of each person entering as they come through !
