Most of us adjust to this situation more-or-less unconsciously and in an ad hoc way: we might be reading something online and think, I need to print this out; or we might just have an inarticulate feeling that we'd rather read a particular book on paper rather than on a Kindle. But I think teachers are going to have to be more conscious of these matters and adjust their strategies for teaching attentive reading accordingly. Last semester, for the first time, I had students reading some of their assigned books on Kindles, and next summer, when I will be leading a summer study tour of England, I plan to put every text that I can on my Kindle so I don't have to schlep a big pile of books around the island for six weeks. Within a year or two I expect to have a much better handle on how to deal with these changes.
