We haven’t had a post on professional issues lately, but I hope that readers won’t mind a bit of light reading. In any case, here it goes:
Suppose that I’ve become a better teacher. Suppose, for instance, that I’ve used the same bank of test questions over the years and that, due to implementing certain non-substantive changes in my PHI X course, students taking that course from me this year are doing a better job answering those questions than students who took the same course from me in previous years. So the material that I’m trying to get the students to learn and the technique that I’ve been using for assessing whether they’ve learned it hasn’t change, but I’ve become more effective in that my current students are, on average, leaving the course with a better understanding of the material than students who took the same course from me in previous years.
The question, then, is: Should I (A) adopt higher standards with respect to what level of understanding I expect from them so as to earn certain grades or (B) keep the same standards and give higher grades on average than I had been giving in previous years?
