That said it reminds me of Larry David on Conan podcast of how he got out of a movie test screening. "I've got one question and then I've gotta go...".
I remember back in high school my teachers would always warn students for doing presentations like that, yet all of them did exactly the same thing. And it was even worse in university, when we had to listen to 2 hours presentation read word by word with monotone voice.
Yup! I even tell them to experiment a little because they get full points either way (my logic is, the social pressure alone is enough to get a good effort, and usually that's true lol).
It's because they didn't trust their ability to remember stuff. But when I lecture, I'm often elaborating beyond the bulletpoints, engaging my audience with questions, making eye contact, etc, so it's not like I'm not setting a good example. I guess my university it's just too late to teach?
Ugh the monotone voice is the worst. A colleague of mine does that. If you are making a presentation and you sound bored all the way through, guess how your audience is going to feel?
