This article seems more reflective of a generational technology gap than an actual loss of student interest in building relationships with professors. The author doesn't seem to want to bother leveraging all the wonderful tools currently available to interact digitally with students beyond the walls of a classroom or office.

I give my students my phone number and encourage texting. I find that sending Facebook messages usually gets a quicker response than emails. And, in lieu of office hours, I prefer Google Hangouts so we can be more flexible with meeting times. (Yes... I've had many "office hour" sessions at 11:00 at night!)

Contrary to what this article asserts, I've found that digital technologies bring me closer to my students. Using tools like Facebook Groups, Google Docs, and whatever course forum software the school is operating on at the time, I get to expand the classroom well beyond our 2.5 hours per week and create a sort of 24/7 learning environment.

I wish I could have had those kinds of opportunities as an undergrad.
