Steve and the authors of Rubric Nation -- Michelle Tenam-Zemach and Joseph E. Flynn, Jr. -- get into it about all things rubrics and rubricization, as well as whatever it is that we are doing, good and bad, as an educational system regarding teaching, learning, democracy, assessment, studentship, dialogue, politics, critical thinking, teacher training, privilege, race, class, and our greater (and lesser?) humanity.  

Spoiler alert: it's "a mess."  But that's what makes this discussion particularly deep and interesting.
