When I attended college I was taught by American professors.
Today, many students complain that their teachers are foreign graduate students who speak poor English.
That’s the way it was in chemical engineering at Texas A&M back in the early 80s. The foreign teachers made a hard major even more difficult.
I switched my major to computer science and it was mostly taught by Americans. It was a much easier major.
Now, most of the CS professors are foreign.
Okla. State Univ., 1974, post-Civil War American History, a Gen.Ed. requirement for all degrees, taught by a Chinese graduate student whose language skills helps me yet today to understand the atrocious “Chinglish” instruction manuals that come with most electronic equipment. Thankfully, the course guide also stated the dates of the exams so that’s mostly when I showed up.
