There have been a number of other questions about grading oral exams, or about which countries use them, etc., but for those of us who come from places that don't traditionally use oral exams, how do you go about, for lack of a better term, write them? Given the amount of online transitioning for courses lately, it seems to me that oral exams would be a good way to ensure that that the student actually learned the material and didn't get someone else to write their paper or copied answers from some repository.
For example, in a Latin class, would a typical question be to translate a passage on the spot? Or would it be questions about "what are the declensions for X?"? Or something totally different? Does it ever integrate previous work ("on your midterm paper you said X, can you explain why you didn't think about Y?") or is it generally totally standalone? All of them above?
Note that I just use Latin as an example, I'm mostly curious on a generic process level, so it would be applicable to all disciplines.
