> At my university, I was taught by professors and grad students, none of whom had a teaching degree.
Professors and grad students may well have done a course on how to lecture. It is obligatory and/or an easy way to pick up credits in many PhD programs. In any event, grad students teaching badly, because the department has allowed the more competent faculty to put their teaching burden on grad students, is a common complaint about US universities.
