I have mentioned before that I am glad to see the introduction of rubrics to our Moodle experience. I am experimenting now with a couple of sets of essay papers.
I have had to learn some of the quirks. It is not possible to edit a rubric once it has been attached to an assignment. So, if there is a mistake, take it off the assignment first before trying to make changes.
Unfortunately, our version only offers two rubric choices, and neither fits what I really want. I am using a "checklist" type, and it requires me to check many boxes, which can get tedious. I would like to set it up so that only the highest applicable box needs to be checked.
Because of that tedium, I tried using the iPad, figuring it would be faster to just tap. The problem there was getting from the rubric to the paper and back efficiently. There might be a way, but I don't know it since the iPad experience is still fairly new for me. I tried using both the iPad and my PC at the same time, but didn't work, either.
So, back to the computer. After about ten papers, I think this method is at least as good as what I had been doing before, copying the grading criteria to each grading box and entering points for each one. I'm just not sure yet if it's better.
