Late last week Jen shared this post about how she has tackled creating rubrics from scratch for her assignments. Today, I share my thoughts on how points can be allocated in your rubrics.
Whenever I sit down to create rubrics one of the things I often struggle with is how to allocate points.
Commonly, we see rubrics with a simple point-to-point system. Something like this:
My problem with this approach is that it is possible for someone to do okay on each item, score 3s, but end up getting a 60% on the assignment. For me the middle of the scale should end up much closer to the middle of the letter grading scale, around a C. I also think that if someone has included all of the elements required on the assignment, they should get no lower than a 50%; they have at least tried and followed directions.
With these two thoughts in mind, I have come up with the following grading scale, which varies based on point allocation, but follows the same logic.
With this approach, the lowest grade a person gets if they included all of the required things is a 50% or an F. Each subsequent level corresponds to the next letter grade: 65%, 75%, 85%, and 100%.
There are definitely some things about this approach that some people won’t like. The difference between grade allocations are not equal. Not doing something results in a big hit compared to doing something badly.
I sometimes struggle with these things too, but this works for me.
That said, I welcome feedback. How can I improve this approach? Do you do something different that you think works better? Comment below or email us at firstname.lastname@example.org
