Two researchers offer data helpful in answering the assessment question. They decided to take a look at a collection of rubrics being used to assess online discussions. They analyzed 50 rubrics they found online by using various search engines and keywords.

Based on a keyword analysis, the researchers grouped this collection into four major categories. Each is briefly discussed here.
