... rubric just makes that transparent...
In my observation and experience, transparency is key to understanding whether grading practices are uniformly applied. Rubrics make it plain to see whether each pupil's work is graded on the same criteria.
While grading assignments "blind" (without knowing which pupil's work is being graded) precludes favoring or penalizing any pupil's work and may be the ideal, rubrics cannot guarantee that degree of fairness.
The opposite of grading "blind" is establishing different grading criteria depending upon the student. The transparency provided by grading criteria being documented in a rubric may help shed light on any grading practices utilizing "
differentiated task demands" designed to create equal outcomes.
