Imagine you are a young pitcher, standing on the mound of your first Varsity baseball practice. You throw the ball to the catcher, and your coach proceeds to tell you that it was a “C+” pitch. What would you think? The example seems ludicrous to us because we know what the young man needs: pointed, specific guidance so that he can improve the pitch. We know intuitively that the letter, in this case, is unhelpful.
Now imagine the same scenario from a slightly different angle. You are the coach. As you approach the mound and begin explaining to the student how to use their shoulders as they throw, you are suddenly interrupted. “Yeah, but did I pass, Coach?” You can imagine the frustration in this similarly absurd example. “A student would never say that!” you think to yourself. And you’re right; they would not. Again, this is intuitive; there doesn’t even seem a need to explain it. Similar scenarios could be played out ad nauseum, with different actors substituted in to show that applying a percentage system of grading to life is unhelpful at best and downright dehumanizing at worst. So why does this same proposal meet with such hesitancy when applied to the classroom?
