Not just grades but:
- Grade distribution for the class. At a minimum: class average, standard deviation, median. Even better: a breakdown by grade.
- Scores of students in the class on standardized exit exams. For example I’d like to see how students who took the class scored on physics GREs.
- Surveys of the students perception of the difficulty of the class. Comparison of this ranking for same students across other classes.
Today, when information storage is cheap, why is it that we have a grading standard consisting of a few lousy letters (less for some schools..you know who I’m talking about!) Should we shoot for a standardized more information content grading standard? Or is the current system fine for the purpose it serves (which varies widely among the users of the grades)?
