Point No Better Alternative

Counterpoint What Ever Happened to Learning?

I hate grading, and I’m sure many other professors do too. It trivializes the effort students put into their work by representing a whole semester of thought and effort with one crude letter. Strengths and weaknesses differ greatly from student to student, and are incomparable. I cannot grade without imagining the disappointments, and sometimes complaints, that will ensue. Nonetheless, I grade with genuine belief.

When we look at graduate applications in the Classical Studies department, we divide them into two groups based on GPA. The whole committee reads the group with stronger grades, while one or two colleagues check the lower-ranked group for applicants who are more promising than their grades suggest. There are a few of these, but not many. Grades are the best guide for us to determine which students deserve to be admitted to our program.

Once we have used grades to make the first cut, we look at the applicants holistically. We explore what strong grades may mean—a hard worker, love of the field, talent with languages, or broader intellectual curiosity. The grades themselves don’t tell us these things, but they imply that it's worth our time to look. This is how almost every such program works, and this process tells us why grades are useful.

Though we have recommendations and a writing sample, grades are the essential filter. Narrative evaluations may tell us more than grades do, but there would be no way to rank them and they would make our process much slower. Portfolios are essential in evaluating students for a program in, for example, graphic design, looking for evidence of a particular skill. Otherwise, portfolios are hard to evaluate (how much editing by others went into a particular work?), and take more time than we have.

Grades are, inarguably, a very crude measure of what a student has learned in a particular course. There is a significant margin of error, and at their best they don't tell very much about a student. They don't distinguish between students who enrolled in a course that included material they were familiar with and students who were pushing themselves to their limits. They also don't distinguish students who found the material difficult from those who were irresponsible and didn't study. There are faults to the grading system, but there is no better alternative.

We need the grading system because our society tries to be a meritocracy, and meritocracies are better than the practical (utopian) alternatives. High school grades are the best predictor of success in college, and without them disadvantaged students would be even more disadvantaged.

We need a ranking system for admissions to law schools or medical schools. Consider, for example, what would happen if all our big universities started giving students narrative evaluations or having them create portfolios. The admissions staff already has a mountain of material to evaluate, and does not have the time to sift through narratives or portfolios. Without grades, they would just rely more on LSAT and MCAT scores, forcing the score of this one test to determine their admission.

Grades look more objective than they really are, and that is a problem. Even in courses with exams that strictly test facts and have very clear rules of evaluation, there is inevitable subjectivity in evaluating lab reports, for example. It is not clear, however, that any other form of evaluation would be better. Portfolios don't pretend to be objective, but they are almost impossible to compare, and narrative evaluations are too often bland and unhelpful.

Of course, single grades are not very informative. GPA's typically are. There is no significant difference between an applicant with a 3.8 and one with a 3.7, but there is a large difference between 3.9 students and 3.5, and between 3.5 and 3.1. Patterns among fields are also significant—a student who is getting B-'s in science courses and A's in history needs to rethink being premed.

Even though we all hate them, grades have their merits, even at the level of the individual course. Most faculty do want to be fair. The very crudeness of the letter-grade system forces us to think about how one B+ compares to the next. It is much easier to evade that kind of responsibility when you are writing a narrative; you can easily let your feelings about individual students influence what you write (this is one of the problems that make writing recommendations very difficult). Whether we are grading exams, papers, or a whole course, almost all of us look at our outcomes and try to make sure that we haven't been unfair. We can't always be sure that we have succeeded, but we are doing our best, and letter grades help.

Grades lead to grade-grubbing and unnecessary competition. They are very, very far from perfect as an incentive or an evaluation. But before we give them up, we should be careful that we don't create more problems than we solve, in the less-than-utopian reality in which we actually operate.

    Ruth Scodel’s essay justifies an admission committee’s reliance on grades as criteria for admitting undergraduates into a graduate program. For the admissions committee, who consider a very large number of applicants, grades are crude but useful data that operate as a shorthand for student mastery and achievement.

    But Scodel’s essay does not justify the use of grades in the first place. To do that, we ought to think not of the interest of the Classical Studies department’s admissions committee, but the interests of the undergraduate students who are the subjects of the grading system.

    Most students would agree that the purpose of education is real and comprehensive mastery of skills and knowledges. To accomplish this goal, students should take responsibility for themselves — but, in addition, good teachers should take responsibility for their students. If the student emerges from the educational process with viable, effective skills and comprehensive knowledges, then both student and teacher have been succesful. If the student emerges without having reached this level of competence, then the whole enterprise has been, if not an utter waste, a failure. Thus, a University that took its educational mission seriously would have no use for a many-tiered system of grading. Such a University would not graduate Classics majors who were prima facie unqualified to secure positions in top-ranked graduate Classics departments (after all, aside from certain creative and entrepreneurial activities, there are few productive ways that a Classics major can put his education to use besides entering academia).

    For this reason, Rothman’s point that the educational system must never lose its essential focus on mastery is a point that is extraordinarily effective against Scodel’s essay, and one for which she has no real counter.

      I do think you’re definitely onto the right idea. The main tension between these two pieces is one of value, i.e., of what each of the writers considers important. Professor Scodel primarily in grades as a tool that evaluates and classifies students (information that may be important when, say, someone is applying to a graduate program or a job), and Professor Rothman sees grades as inhibiting students’ learning. I think they both argue their respective cases well, and the really tough thing is deciding whether we want to prioritize evaluation over learning, or vice versa.

    • Aaron Bekemeyer says:

      Professor Scodel is interested* primarily in grades…

      Sorry for the typo!

      Ben,

      Your argument is accurate–Rothman’s main point is indeed that the educational system must always focus on mastery. I also agree that the university should take responsibility for the students. I believe, though, that Scodel has an effective counterpoint to Rothman’s argument. She suggests that there is no better alternative to the grading system, which Rothman does not successfully refute by failing to suggest an alternative to grades. Do you think there is a better alternative to determine mastery in a certain subject?

      Also, I must add here that I disagree with your comment about “putting a Classics major to use”. I believe that any liberal arts degree will prove useful (“productive”) within a variety of jobs or graduate schools, not necessarily within academia. Graduating from a top-ranked Classics department puts one at an extremely marketable position for many research, anthropology, or archaeology positions.
