Student Grading
If you are confident in your homework solution, send me an email with the subject line [grading] name-of-task. I will grade your task first and if it is OK, I will give you extra points for grading the solutions of your classmates. The formula for how many more points you get is $r \cdot b/5$, where $b$ is how many points the task is worth and $r$ is the number of solutions you will grade, so if a task is worth $6$ points and you will grade $10$ students, you will gain $10 \cdot 6/5 = 12$ points. You can become a student grader at most $3\times$ a semester.
Logistically: the way it works is that I give access to the grader in OWL, he grades and assigns points, and I see all of it and can make corrections if needed. The grader should carefully read and evaluate a solution. Is the solution correct? If not, where did the author make a mistake? What are they not understanding and how could I help them understand? What question will push them in the right direction? Next, is the solution clear and easy to understand? Would it be helpful to split the solution into more paragraphs? Introduce some notation? Etc. Based on this the grader will suggest a number of points, for example:
The solution is essentially correct, but I would suggest instead of using the notation A, B, C to use an indexed notation A_1, A_2, A_3. Otherwise, the proof was structured relatively clearly.
… and then give 2 points for the task.
If I feel a need to add anything to the feedback provided by the grader or to change the amount of points awareded, I will do that (but it only happens rarely).
The grader's responsibility is to correct all the assigned tasks within a week that they become accessible to them in OWL.
