I had never heard of  metarubrics. I can see how they would help to create rubrics.

I found several already made for my class and thats where I am going to start. I can edit them as needed to make them my own. 

Rubrics can have too many componets. They also can help with self and peer assesments. Students will become more aware of things when using the rubrics.

Using rubrics are important to keep the students knowing what is expected of them at all times. Rubrics are very time consuming for the instructor and may have to be updated often depending on the class.
