I always encourage my students to record my lectures,I have nothing to hide. Most of my students don’t take notes, they snap pictures of the blackboard with their phones while I’m teaching.
Sound good. Just what any sensible person would expect, and just what I'd be doing if I were in college these days.
There are some real ulterior motives involved with any administration or professor who wants to ban recording devices, and the motives don't have anything to do with what will most help the students learn
When I was teaching in Turkey, I used Powerpoint slides. The custom was that the professor's notes (or in my case the slides) would be taken to a print shop by one of the students. Other students could they buy copies of the notes or slides. This was because textbooks were so expensive. Most were imported. It worked out well for me and my students.
