De-emphasizing Grades

 The Assessment Trap, Part 4. De-emphasizing Grades

(This is a slightly edited version of a post from 2011)
(If you want to start reading at the start of the series, click here.)

When students learn their grade for a given course, what they are learning is how they compare with their peers, which is one indicator of "how they are doing". (See the last post in this series.) Grade or no grade, many students know exactly where they fit in the classroom hierarchy, though some may not admit it to their parents or even to themselves. It is true that some (often boys) overestimate themselves, and others (often girls) underestimate themselves. For those students, knowing the grade may be a helpful corrective. But is it a good idea, educationally, to dwell on comparisons between students?

Like many teachers, I am reluctant to make comparisons between students. Such comparisons are unfair and unproductive. Unfair, because students come from many different family and educational backgrounds. Comparisons between students end up being largely about that. Unproductive, because it is not realistic, in most cases, to expect major changes in the short run. A hard-working C student may need years, not weeks, to become a hard-working B, or even A student. We can point them in the right direction, offer them intellectual tools, help them to improve their work habits, and over the course of their high school career we can see spectacular changes. And we often do -- this is one of the most satisfying parts of working in a strong department.

But paradoxically, the way to get there is not to dwell on the grades. (It's a bit like searching for happiness -- you're more likely to find it if you don't dwell on that as a goal.) At most schools, the conversation is about "what do I need to do to get an A?" (or a B), and of course, that is the subtext of many conversations at any school. The teacher's responsibility is to deflect that conversation towards the specifics of this particular student's needs at this stage. Perhaps the A is already guaranteed, but the student needs to focus on their ability to communicate their ideas better. Perhaps the A is just not going to happen this term, but the student needs to work on developing their symbol manipulation skills, or their ability to write a logical argument. There is always work to do, and a time to stop working, irrespective of where the student stands in the grades distribution at this particular time.

A grades-focused conversation means that in these very common situations (the A is guaranteed, or the A is unattainable at this point) there is little to discuss. It can also lead to grade inflation in a variety of ways: in order to motivate students with the grade, we might make it easier to attain. Or in order to not be hassled, we might make A's more plentiful. Grade inflation is not the end of the world, but if we want to inflate grades, we ought to do it deliberately and not as an unexpected consequence of uncomfortable conversations.

If a student's place on the academic ladder is constantly harped on by the school culture, students can internalize the label and stop striving. This is what is now known as a fixed mindset. Skillful teaching is in part about bringing out students' different strengths to the fore, and building on them, whether or not those lead to a better grade in the short run. For example, a strongly visual student can contribute a lot to a discussion, even if he or she is not yet ready to translate that talent into points-earning write-ups. Over time, such engagement does lead to better grades.

Bottom line: intrinsic motivators (such as interest in the subject matter) are more powerful, longer-lasting, and more meaningful than extrinsic motivators (such as grades.) Our task, as teachers, is to move students from the latter to the former. It is a challenging enterprise, but we must try to keep the focus on the discipline we teach and our own passion for it, rather than on the lines separating our students into A, B, and C. Teaching students to be self-motivated learners, and modeling that relationship to the subject, is a vastly more useful contribution to them as lifelong learners than the Pythagorean Theorem or the quadratic formula.
