IMO an hour long lecture is way too long. Human brain can’t focus on one thing for that long, especially if it’s just someone eating w PowerPoint. When’s the lecturer gives of the impression they don’t want to be there themselves (or have no interest in what they’re talking about). Lecturers have left mid-session to return later while on my undergrad one straight up said uni wouldn’t let him get away with not giving lectures.
What’s the perfect length for them you think?
