A call to arms for handheld devices

What are the obstacles preventing the widespread use of mobile devices for CAA? This paper is intended to stimulate discussion on how to best introduce mobile devices to learners, and how to provide optimal support for mobile CAA. The discussion is an opportunity to more clearly delineate obstacles and therefore arrive at better solutions to the challenges of mobile CAA in FE and HE. Some of these are common to the introduction of CAA in general, others subtly different because of the nature of the delivery platform.
