I was part of a Classics Facebook group called #GuestNatter, where people could volunteer to chat about a topic or to solicit help. I did a video conversation with a colleague a Oberlin for his class, and I invited five colleagues into mine. The conversations I recorded with colleagues were a real grab-bag, but they were really great for sharing information that you might otherwise do in a lecture. Whereas a lecture can get pretty boring, I think these were a lot more engaging—and students often referenced them in other assignments, so they were popular with at least a portion of the class.
