The Peerwork plugin was designed to replicate functionality of WebPA in Moodle allowing a peer weighting to be applied to assignments. Using this plugin teachers still grade the assignment, but available marks are distributed between students based on peer ratings.

A common complaint from students working on group assignments is that all students receive the same grade regardless of the amount of individual effort / contribution.

The Peerwork plugin was designed address this by allowing teachers to grade work, but for the available marks to be distributed based on peer assessments of students contribution to the assignment. Within this plugin teachers can:

  1. Set up as many criteria as are needed
  2. Apply Moodle scales to the criteria (usually Likert)
  3. Apply privacy settings / visibility of peer scores and comments
  4. Apply a weighting to the peer element
  5. Require students to complete peer work
  6. Report activity completion based on students completion of peer review
  7. Give students option of leaving feedback comments (can be anonymous)
  8. Grade assignments (teacher)
  9. Modify peer weighting by group
  10. Override final grades where necessary
  11. Control visibility of peer marks and comments to other students
  12. Release grades for all students at the same time
  13. Download csv exports for entire class or individual groups

This plugin was offers an alternative to WebPA natively within Moodle.

    Thank you. I have replied there.

    Might be worth changing the example screenshot so that the penalty doesnt only apply to the chinese name.
    Seems trivial, but has bad optics.

    How can I add likert scale on scoring type?
  • Tue, Jan 19, 2021, 7:03 PM
    You just need to add the scale as documented here:

    Once added, it will be available in Peerwork settings

    Hi Peer Work devs / contributors

    Are there any known problems with Peer Work when self-evaluation is turned off? My contribution and calculated grades are way off when 'self-grade' is set to No.

    Even if all students give each other identical marks (which should in theory result in them having an equal contribution and calculated grade), the results don't reflect this. In the below example, 4 students in total each mark their 3 colleagues, but not themselves. All students marked all other students '3' on every scale / criteria. The same problem also happens if the scoring is done randomly.

    Name Contribution Calculated grade Penalty Final weighted grade Revised grade
    Test Student 1 0.0000 0.00 0% 30.00
    Test Student 2 0.4444 26.67 0% 43.33
    Test Student 3 1.1111 66.67 0% 63.33
    Test Student 4 2.4444 100.00 0% 100.00
    Total 193.33 236.67

    When the same test is run with self-grading turned on, and with all students awarding '3' on every scale / criteria for all other students, including themselves, the problem does not occur.

    Issue #58 referred to above has been fixed in v2.3.0 However, this will result in a change to grades for existing Peerwork activities with self grading turned off. The change will not automatically filter to the gradebook. The gradebook is updated when the Peerwork grading page is saved.

    Thank you User:Sam Cole for highlighting the bug. I have added tests to cover self grading options.

    If a Teacher accidentally grades one of the groups before the due date, it prevented others in the group from submitting. I could not find a way to retract this so perhaps a check could be made to prevent grading before the due date?

    We also found a display issue when the grading scale exceeds the available window space (eg. an 8 point likert) the radio buttons wrap but the scale headings do not which has the potential for students to select the wrong value.

    Thanks for reporting Stephen. Could you file a report on these issues in the bug tracker and I'll take a look?

    Thanks for the quick response Amanda, I've done that.

    Thank you. I am attending Moodle Moot next week, but I will look at these asap after that.

    Hi, there is a bug related to 'Export all group grades' function. If teacher changes the penalty of students with no submissions from 0 to a number after giving group marks in each group, the final marks are calculated with penalty. However, when clicking 'Export all group grades' button, the final grades in the downloaded Excel do not involve the influences of penalty. But, if the penalty is set up before students give peer assessment submissions, the final marks in 'Export all group grades' Excel sheet are calculated with the influence of penalty.

    @Amanda I do not think they are the same. The one that is already reported is about the calculation result. But the bug I found is about the data in the download Excel sheet is different from the data in the Moodle web page. I have wrote down this issue with screen shots in bug tracker.

    Hi, I have mod_peerwork 3.11.0 on my moodle. When setting a peer work assignment, I use some HTML formatting elements in the "description" box. However, it seems that HTML formatting is stripped from the view page. All the students see a single non-formatted text paragraph. Is there anything I can do to show the formatted description on the view page? Thank you very much.

    Great plug in. much simpler than workshop without all the maintenance. Wondering how I can deal with group presentations where individuals grade a group of students and they all get the same mark?
