Student solutions to exercises will be evaluated in part by peer review. Your main focus in peer review should be your written feedback; however, you will also translate this feedback to numerical scores according to a standard grading rubric given below.

Comments

As a peer reviewer your primary task is in providing good feedback to the submitters. Similarly to when you would peer review research papers for publication your peer review should show (a) understanding of the submission (b) discussion the quality of the submission pointing out good and bad aspects. Your peer reviews will be evaluated by how well they achieve this goal, and also their clarity.

Scores

Each rubric element has 10 points. Think of the rubric scores as follows:

10 Excellent: The student's writeup would be hard to improve.
8 Very Good: A reasonable writeup for a homework in a class (the grade for a good and correct solution).
6 Good: Could have been better.
4 Poor: Mostly on the right track, but significantly far from giving a full solution.
2 Very Poor: Contains something that is on the right track, but is mostly wrong or non-sensical.
0 Zero: Does not contain much of any semblance to a correct solution.

These scores do not literally translate to each rubric, use your best judgement in applying them.

Multi-part Assignments

If an assignment has multiple parts, grade each part as a fraction of the rubric. For instance, if it has two parts, grade each part out of 5, according to the rubric, and add them together to get a score for each rubric element.

Rubric Elements

You will be rating each submission according to the following rubric elements.

Answer: The answer given by the submission is correct and as good the published solutions.
Argument: The argument given by the submission that shows why the answer is correct is complete, correct, and takes the most direct approach. (It is ok to take a different approach from the published solutions, as long as it is as direct.)
Clarity: The writing of the submission is clear, concise, and easy to understand. Small grammatical errors are allowed as long as they don't detract from understanding.
