I recently had to do the one thing that I dislike most about being a college professor: assign final grades. For me, giving out grades is definitely a necessary evil. I find it so frustrating that an entire semester of thinking, learning, exploring, and discussing comes down to assigning a letter or number to students. And yet, I know I must do this to keep my job. To put this in succinct sociological terms, my agency (my capability to act) is constrained by the institutional structure (the rules of the university that I must follow).
