In my role as intructional faculty, I aim to grade everything anonymously, which is a provision I enjoyed as an undergraduate. My current method is to ask students to write their names on the back of their papers and exams, which also helps me to return them. One of my students remarked that I must do this because I am particularly biased. She may be right. But there is reason to believe that we are all biased against minority groups in our grading practices. Take this publication on the perception of grammatical and spelling errors by partners at 22 law firms: "The exact same memo averaged a 3.2/5.0 rating under our hypothetical 'African American' Thomas Meyer and a 4.1/5.0 rating under hypothetical 'Caucasian' Thomas Meyer. The qualitative comments on memos, consistently, were also more positive for the 'Caucasian' Thomas Meyer than our 'African American' Thomas Meyer." It seems obvious to me that these effects could have an impact on the grading of philosophy papers and exams. (It may be worth noting that the gender/race/ethnicity of the partner did not affect these findings, although "female partners generally found more errors and wrote longer narratives"). And take this publication on faculty assessment of a student applicant, mentioned a couple of years ago here at NewAPPS: "Our results revealed that both male and female faculty judged a female student to be less competent and less worthy of being hired than an identical male student, and also offered her a smaller starting salary and less career mentoring." The difference in mean rated competence, hireability, and mentor-worthiness was of the order of 10%. Again, it seems obvious to me that these effects could have an impact on the grading of philosophy papers and exams, which could be a grade-letter difference (i.e. the difference between a B and a C). Since perceived differences in grading standards could have an impact on whether students choose to stay in philosophy, it seems to me that anonymous grading would both be more just and would encourage a more diverse range of participants in philosophy (see other suggestions on this over at Daily Nous). What does everyone else think? Do you grade anonymously? If not, why not?
