Today I came across an article at Chronicle about using twitter in (and out) of the classroom. There are a lot of links to previous and related posts on the subject (like this example assignment), and the commenters also contribute some useful (and self-promoting...my favorite!).
My first instinct was to dismiss the use of Twitter in the class as just another attempt to district our little snowflakes with another shiny tech tool.
But....as I eye my growing mound of lecture notes and ponder my insane schedule for the fall, I had to wonder: what if, one day, we actually teach a whole class via twitter? 140 characters sure don't take up a lot of space in a lecture notes binder! Think of how fast prep would go!
