Technology abuse

I teach Labor Law as an adjunct, and have done so for a number of years. Each year I debate the value of allowing students to use a laptop in class. I am reasonably certain it adds nothing to the learning experience, but I have felt that adult students can chose not to listen to me, and am reasonably sure that doing so affects their grade adversely, because I provide a pretty good roadmap to success on a very difficult exam. Maybe I should revisit the issue as this article suggests.
