I can corroborate that it gets crazy even in courses expecting high literacy. I had the painful experience of teaching a 3rd year course in communication studies that was part of the media production stream. It required writing preproduction documentation and a script. There were a lot of questionable attempts but there’s always a range of interest and skill, right? One student, and let me remind you this is third year at a university, I called into office hours. I’m a fan of poetry, so I just had to be sure that she wasn’t cleverly lampooning Gertrude Stein in some ironic way. Sadly, no, she just had no fucking clue how to write ANYTHING coherent. Amazing.
