I agree you must have a back up plan, when you're ready to start the lecture and you loose all of your A/V electronic communcation it quite inconvient to both the instructor and students because of the time spent shifting gears and grabbing text books and notes.
As mentioned tech, and in particular discussion posts, are a good way to level the playing field and engage students who tend to be introverts while limiting the extroverts who can dominate discussions.
Involving device in delivery of lessons make sense. Heck, studentsare already engaging with devices during lectures. Why not put the focus on the lesson while allowing the use of devices?
