Moving toward a physical backpack, Wolfson and Amirian (2003)
identified a digital backpack as a backpack loaded with the technology
associated with professional development. The purpose of their backpack
was to provide technology access to professional development participants.
Viewing it slightly differently, Henke (2005) depicted the digital backpack
as a backpack filled with student-selected tools (e.g., cell phone, digital
camera, iPod, calculator). Within the one-page display, Henke indicates
that students would select tools in order to better their learning. Henke
also depicted a potential learning outcome for incorporating each device.
For instance, a student could use an iPod to listen to a podcast on academic
content.
