A digitally fluent instructor is able to compare, contrast, and analyze differences in technologies, and understand how those differences might impact their pedagogy, and adjust accordingly. This ability to adjust accordingly is, to me, one of the biggest traits that distinguishes the digitally fluent instructor from the digitally literate one.
Clint Lalonde, wondering whether this ever comes down to definitions? Building on Doug Belshaw’s work on digital literacies, I think his elements capture all the aspects of fluency that you talk about? Maybe the issue is that digital literacy has become a dead metaphor?
