Ive never created a rubric, but i have used them as they were done by a supervisor. I do understand it takes time to make sure it concise and fits all types of students ability. It must be reliable for it to be succussful
Valid and reliable rubrics will enhance the learning environment. The construction and layout of the rubric is key for understanding its use. Student success in a particular assignment ways heavy on the language of the rubric.
When developing a rubric you are looking at content, clarity, usefulness and reliability.
I would think that a supervisor could use a metarubric that was developed by a higher level instructor who could take on the task of developing these.
This is the first time I am learning about metarubrics. I can see why professionals would need it.
