Sometimes you tried to create interactive lectures where students are active and participate in the lecture, ask questions and give feedback. This can be hard even in a co-located lecture but can get really frustrating on distance.
In one of my courses, I had a lecture the I used to present with a colleague: Doing paired presentations is really nice, its easier to govern the pace of the presentations, you can interrupt each other and it creates a bit more dynamics in the lecture. When my colleague stopped working at LTU, the lesson felt much more boring so I decided to do something about it so I invented Dan the Donkey, my virtual sidekick!
I have used him for several years and I add a bit more interactions from him now and then when I see that the students misunderstand some concepts, then it’s easy to use Dan to ask the questions that the students did not dare to ask…
