A rubric is a matrix presenting the criteria you will use to assess student work. Rubrics allow instructors to define different levels of performance, identify different dimensions of performance, and describe student performance at different levels.
Why Use a Rubric?
Body
Rubrics can:
- Let students know what sort of performance to aim for
- Explain what you expect before an assignment is due, rather than after
- Promote consistency across sections and across individuals
- Confirm your priorities for an assignment and explain criteria that are important
- Permit students to evaluate their own work
- Model the language of your course, assignment, and discipline
- Communicate to the entire class about expectations
- Save time by routinizing some forms of evaluation
- And thus make time for more personalized evaluations as needed
Rubrics are both a solution to a problem and a communication strategy. They can help to address many problems, such as:
- Frustration from repeating the same comment on many students' assignments
- Lack of time to comment as much as you'd like to
- Questions from students about your expectations
- Difficulty deciding what grades to assign on given pieces of work
Analytic Rubrics
Body
Analytic rubrics describe two or more aspects of performance, with scores divided across aspects. This means that:
- Students get detailed feedback about particular aspects of their work, and relative strengths/weaknesses
- Faculty get structured guidance about their own evaluative process
- The rubric can take significant time to construct and possibly to use (depending on its complexity)
Holistic Rubrics
Body
Holistic rubrics describe overall performance, with a single score. This means that:
- Students may not understand why their score is what it is
- Faculty get clear and quick rankings of students
- Quick decisions can be made in situations where feedback isn’t needed or desired
Reflecting on your Assignment
Articulate your Goals
Body
- A rubric depends on an assignment for context. The assignment is your rubric’s foundation, and your directions to students and your rubric should be in harmony.
- A rubric doesn’t repeat the assignment, but a rubric should describe the products your assignment sponsors.
- If you begin with attention to what your deep goals are for students, you’ll approach the rubric in a good frame of mind.
- What do you want students to learn, make, or do?
Describe the Task
Body
- What does your assignment involve? What stages, components, or processes does your assignment depend on?
- What challenges might students encounter and what might be unclear to them about your expectations?
Constructing the Rubric
Name Performance Dimensions
Body
- Every task has features that can be described in more/less detail. Selecting features for a rubric means describing the essential features you want students to focus on.
- This may vary depending on their level of experience and the purpose of your course. These dimensions become the leftmost column in a full matrix rubric.
- What are the defining components/features that you will grade?
Decide on a Scale
Body
- Use the fewest scale points that are practical for the decisions you want to make.
- Set up the scale so that it reflects the kinds of decisions you will find easy to make.
- How will you name scale points (1-4, A-F, Excellent-Poor, Novice-Expert…) and how many scale points do you want?
Describe Performance Dimensions across the Scale
Body
- What does performance at different levels look like?
- Descriptions should make your expectations tangible to students: the value of a rubric lies in its ability to convey what success looks like.
- Be specific (simply asserting that work should be excellent doesn’t tell students what excellence means) and should avoid quantitative measures (which are better suited to a checklist).
