Allowing laptops, as UD often says, is academic malpractice.
Professors who continue to allow laptop use fall into the following categories.
1. I could give a shit. It’s easier for me to do virtually nothing up there if students are sedated with their fun screens. To make matters perfect, I use old text-heavy PowerPoints and drone and dribble over them. Eventually my teaching will resemble my deep calm when sleeping off benders, and my classroom will be a morgue.
2. I hate and fear humanity, especially students. I look forward to the day when all of them will be hidden from me behind their screens.
That’s about it.
