The Problems With Grading
The issue of grading was at the forefront of my attempt to differentiate instruction in my class. As I mentioned before, I graded everything equally, whether it was easier or harder. However, on quizzes, they needed to show they could handle the harder material to receive a better grade. We discussed grading extensively during the class. I had the idea that the level 1 assignments be capped at a C, level 2 at a B and level 3 at an A. This way the better students are rewarded for their skills and knowledge. But I ran into a moral dilemma. Was it fair to cap students’ grades in this way? I guess if they wanted to do better they would try harder and start completing the more difficult material.
Actually, the more I write about it here, the more it seems completely logical and fair. But I’m sure my original objection exists out there, especially by some people who may read this. What do you think?
This class also focused on rubrics as a fair way to grade students’ assignments. That is like the Holy Grail of grading. Make the perfect rubric! Share it with the class! Get them involved! Be specific!
I got an e-mail linking to the blog Ecology of Education regarding this topic. Titled, “The Folly of Rubrics and Grades” the author makes the case that no rubric can be perfect and, in fact, the idea of a rubric is wholly misguided. A few quotes:
For some reason, making these categories out of 4 or 5 or 10 seemed to be a popular way to go. But to this day, I have not reconciled some of the problems that developed from choosing the 4, 5 or 10 scale.
Most rubrics I’ve seen do not go beyond a 5 point scale. I use a 4 point scale for my lab write-ups.
If I pick the four scale, there is nothing in between 75% and 100% which means that in order to get ‘honors’ (over 80%), I have to assign a perfect grade. If I pick the four scale, there is nothing in between barely passing 50% and 75%. That’s a large leap. If I pick the five scale, it is awfully tempting to just pick 60% as it is a pretty average grade that lots of kids might fit. If I pick the five scale, there is nothing between 40% and 60%, so someone who I’m not comfortable with getting 80% will get the same 3/5 mark as someone I was not comfortable with giving a 40% failing grade.
Awfully good point there. In our grading scale, the only possible grades are F, B-, A. That’s a pretty big difference.
But if I start to go to a larger scale like the 10 or 100 point scale, can I really say with any certainty what is the difference between a 6/10 and 7/10 or a 67/100 or 68/100?
He can’t, and I certainly cannot. Can you imagine making a specific rubric with 10 different descriptions of performance? How about 100?
This starts getting really difficult at this point. What’s the right call here? I have no idea but it’s something that can be debated for a long, long time.
