Sharing is caring :) I have posted the lectures of my course Structural Geology on the following YouTube playlist. I ask the students to watch these lectures before meeting to the class. That way we can concentrate on solving exercises in the class. That worked better than the standard lecture format, but it is still challenging. Sometimes the students don't have time to watch the movies, and some of the material is rather hard and requires watching the movie several times. But in any case, the movies can also be a way to study and review the material. Feel free to use these movies in your own teaching
