Just imagine the accents that poor Milwaukee kids are being asked to decipher.
Especially the math students.
A problem of long-standing in colleges with foreign graduate assistants teaching lower-level courses. My memory of a Chinese grad student teaching a required American History after 1865 course is still with me over 50 years later. I spent a long time trying to decipher his pronunciation of “manifest destiny” & “social Darwinism” in the early part of the course. I was a kid from small-town Oklahoma who had very little interaction with any foreign accent.
