The mobility of these devices, and how they are used, have two other important implications for student learning. Ubiquity influences, and interacts with, the content and styles of learning: first, the rise of an increasingly visual culture, and the particular ways in which handheld devices encourage increased interaction with video and multimedia; and second, how these devices have given rise to an increase in social networking technologies and practices, which support increasingly collaborative learning activities. How learning is changing in this new environment, and how teaching and course design need to change in response, raise a host of empirical questions that desperately need rigorous and systematic investigation.
