As stated in other comments, diplomacy doesn't work on tenured individuals. I'm not trying to get the professor to change their lesson plans, that's impossible.

As stated in other comments, diplomacy doesn't work on tenured individuals. I'm not trying to get the professor to change their lesson plans, that's impossible. I'm trying to make them aware that some are struggling and that explanation is more important than slapping code up on an overhead. Spaced formatting is fine, forcing it on your students is unconscionable and inexcusable. It wastes gobs of time in editing that should've been spent thinking about flow control.
