It is taken for granted that students taking a course will receive grades. But when we give a course or workshop to colleagues, or when we follow professional training as part of our jobs, nobody even thinks of handing out grades. We’d actively protest, I believe. This would be silly. We’re adults, thank you very much!
We don’t mind being assessed. In fact, many participants in courses, workshops, and training programs welcome feedback, positive and negative (constructive). And we expect to be tested. But we expect the result to simply be pass/fail. Why on Earth should we get grades on a scale of 1-10?
But then, what’s so different with students?!
