Ricardo, using smart phones in class is a common issue. There are several different replies to this issue and they range from incorporating smart phones into your lesson plans or not allowing them at all to be in sight of the instructor. Some institutions have had students sign agreements where instructors are authorized to confiscate the phones and students must pick them up from the Dean of Students or some form of administrator. I am in favor of finding some way of incorporating them into the lesson plan but each situation is different. Please let me know if you are able to make a difference with the techniques you have learned in this class. I am sure other readers would be interested in your results. Thanks for anything you can share. James Jackson
