bad teaching examples from personal experience: --- >you have 1/5 exercises wrong and therefore sit in 2 hour long exercise sessions waiting for that specific exercise to be solved. (20 students * 20% * 2h = 8h wasted)
>lectures add no value or excitement to content. Most students learn it better and faster reading the script. video lectures are also very bad. You mainly go to the lectures for social interaction or a clear conscience.
>a friend made a teaching internship in Uganda this winter: the kids have school for 15h a day. They didn't learn anything, it was basically to keep them busy and increase the price for the girls when they are married off
There are many more and better examples, these are just from the top of my head. For me it is just so frustrating to see, especially for the other people. For example, there are physics lecture that were given for the past houndred years, how can my professor then give them in such a bad way that noone understands, but after a 1min youtube video, it is all clear.
I will apply for a TA position next semester. At some point in the future I (try/)want to create high-quality opensource content. In our time it makes no sense that thousands of professors give the same, but bad online lectures, all around the world. I could go on and on...
Thank you for your input and ideas
