See how this works in the visual tour, from the student and from the instructor points of view.
Students can see which reviews they need to do from the main assignment list they see once they log in.
Reviews are assigned one by one. To perform reviews, students click on a button Request review, and are assigned a submission to review. The students can read or download the submission, and they are presented with the rubric for reviewing it. Students need to complete a review before they can ask for the next submission to review.
Reviews are anonymous. CrowdGrader does not show the identity of the submission's author to the students reviewing it, and it renames the files uploaded by the students to preserve anonymity.
For each assignment, students need to complete at least the number of reviews specified by their instructor, or their review grade will suffer.
Resistance to collusion: CrowdGrader is resistant to collusion, since students cannot choose whose submissions they review.
Students can write feedback for the submission they are reviewing using the CrowdGrader editor. If the submission consists in a CrowdGrader document, the students can use the review tools to directly annotate the document:
If students do not understand some details of the submission they need to review, they can discuss it with its authors in an anonymous forum. In this way, small mis-understandings can be cleared up without affecting the grades.
Instructors can easily see the list of submissions, and the grades they have received so far. They can also see the amount of disagreement on each submission, and they can sort the reviews in order of greatest-disagreement-first. Instructors can also choose to grade some of the submissions themselves: their grade will take precedence over the grades provided by students when computing the final grade.
