I am enjoying a Dagstuhl seminar on Using Networks to Teach About Networks where people talk about their experience with modern teaching methods such active learning, flipped classrooms, online learning, peer reviewing, and learning analytics when teaching computer networks. (Some people even talk about using blockchains to maintain student records.) And then there are of course discussions about what do we teach students and why and which tools people have found useful for student labs.
I heard some terms I did not knew before. A new one, for example, was sandwich classroom, i.e., a flipped classroom turning into a preparation phase, the classroom discussion phase, followed by a post studying phase (often using the same material used in the preparation phase).
There are certainly a few things I heard people using successfully that I will try out in the future.
