After reading a recent Wired article about applications aimed at users’ secondary attention, I started thinking about new ways to use mobile devices for learning: second screen apps. Second screen apps are mobile apps that are typically used to complement television viewing. Why couldn’t they be used to complement learning events, too? Couldn’t a second screen be useful during instructor-led classes, live virtual classes, and asynchronous e-learning courses?
The use of a second screen during instructor-led training may be the easiest to imagine. A smartphone or tablet could be used to obtain complimentary content, connect to an instructor, or interact with other learners. A class at the University of Texas at Dallas uses Twitter to promote class discussion. Similarly, many conferences have adopted the use of back channels to enhance audience members’ experience. In 2008, I was in the room (and oblivious to the back channel) when the audience turned on Mark Zuckerberg’s interviewer using a Twitter back channel. A few things are gained from these experiences:
- The voices of many audience members are heard, not just a handful of outspoken participants.
- The instructor/speaker gets live feedback from the audience.
- The content can be modified based on the live feedback.
- An online archive of the discussion is available both for attendees and those who could not attend.


Instructional designers should apply the ADDIE Model to every aspect of their lives. It is particularly important on Thanksgiving Day.
