Here's another study that contradicts the widely-held view about the existence of a "digital divide" between so-called digital natives and digital immigrants. Guo, Dobson and Petrina (2008) collected data from over 2,000 pre-service teachers between 2001 and 2004 and concluded:
"there was not a statistically significant difference with respect to ICT competence among different age groups for either pre-program or post-program surveys. This study implies that the digital divide thought to exist between “native” and “immigrant” users may be misleading, distracting education researchers from more careful consideration of the diversity of ICT users and the nuances of their ICT competencies.
