So what do we do about this? For me, the course of action is clear: We need to walk away from traditional grading --- in which I include not only multi-interval letter grades but also grades based on statistical point accumulation. We've seen enough. Grades are harmful to students' well-being; they do not provide accurate information for employers, academic programs, or even students themselves; and they steer student motivations precisely where we in higher education do not want those motivations to go. There is no coherent argument you can make any more that traditional grading is the best approach, in terms of what's best for students, to evaluating student work. If we value our students, we'll start being creative and courageous in replacing traditional grading with something better.
