Hi Janna,
Thanks for taking the risk of being the first to post here. From the sounds of things, you're working to develop a rubric for a course that's not your own -- a scenario I also find myself in.
I found that your critieria are clearly written, and I could understand what was expected at each stage. As you mentioned, you haven't sorted through the weighting yet -- and I wonder if variable weighting for different components would make sense for this assignment (e.g. I might consider weighing content much more heavily than submission).
My other question for you would be whether you would consider reorganizing presentation Rather than having the 0-4 checkboxes, I might put the meets expectations criteria directly under the number 3 (assuming that's what grade would be given), with the space to the left for items that exceed expectations and earn a four, and space to the right for deficiencies that might merit a 1 or 2.
