ABSTRACT
It was Sunday night and I was grading yet another student's history essay that used nothing but vague generalities without a single, specific example that the class had supposedly learned while studying that unit. I wrote “Be more specific” in the margin, listed a few examples of the historical events that the student should have given as evidence, and gave the essay an appropriately low score. Sighing, I started the next essay and experienced the same frustration and disappointment yet again.
