I currently have data from two university programs about Mobile Device Usage on their campuses. The research comes from the University of Central Florida Mobile Strategy and Innovation project and the Ecampus at Oregon State Univerisity. I am finding too that our campus @ Ventura College (a California Community College) has similar statistics.
Additionally, I am finding that faculty perception of device ownership differs from the actual percentage of ownership by students. Consequently, I am wondering "What do you think the percentage of ownership of Smartphones is in your classroom?"
The Pew Research Center also has statistics on this type of ownership.
