EDUCAUSE has published The ECAR Study of Undergraduate Students and Information Technology, 2008.
Here's an excerpt:
This 2008 ECAR research study is a longitudinal extension of the 2004, 2005, 2006, and 2007 ECAR studies of students and information technology. The study is based on quantitative data from a spring 2008 survey of 27,317 freshmen and seniors at 90 four-year institutions and eight two-year institutions; student focus groups that included input from 75 students at four institutions; and analysis of qualitative data from 5,877 written responses to open-ended questions. In addition to studying student ownership, experience, behaviors, preferences, and skills with respect to information technologies, the 2008 study also includes a special focus on student participation in social networking sites.
