Enforce Valid Values in Peer Review Rubric Scores

Enforce Valid Values in Peer Review Rubric Scores

When a student is assigned a peer review with a rubric attached, there is nothing to enforce that a student enters valid values. Students can

  1. Submit a value larger than the maximum for a criteria
  2. Submit a negative value for a criteria
  3. If using fixed criteria scores, not ranges, the student can submit a value between categories
  4. If you are expecting whole numbers to be entered, there is nothing to enforce this

Here is an example of a rubric filled out by a student that canvas accepts because no checking is done on the values the student enters. 

A Rubric where the values entered on a Peer Review are invalid but still accepted by Canvas.

  • The first entry is both a decimal value and outside of any of the 3 scoring criteria, violating points 3 and 4
  • The second entry is negative, which violates point 2
  • The last value is above the maximum, which violates point 1

So giving the students a rubric to fill out in a Peer Review seems pointless because there is nothing in Canvas that forces the student to follow the rubric they are given.

What I want is something that enforces that the students enter valid values when filling out the rubric.

This is causing problems at UBC's business school. We are experiencing a closely related problem. It turns out students can enter non-numerical values, such as text. If a student enters this type of invalid data into a rubric (i.e. I entered the text “A”), then there is an error in the rubric, and the student sees that the “peer review is not finished yet”. But when the page is refreshed, the peer review is considered complete. This undermines the effectiveness and robustness of the peer review tool, similar to the example cited by Matthew here. erica.hill@sauder.ubc.ca - do you have further comments here?

Hi @tim_kato and @mfbutner ,

Yes, just a few clarifying points.  When the student enters an invalid answer in a rubric used for a peer evaluation, the instructor sees the peer evaluation as 'completed'. this means that a student who does not do the peer evaluation correctly, will still be seen in Canvas by the instructor as being done correctly and get full marks.

This also has implications on the students receiving the peer evaluations. If there is no notification or way to identify that a valid peer evaluation was done, the student who submitted their work will get no valid feedback to improve their work.  This majorly reduces the effectiveness of putting in the effort of creating and monitoring this.

Once a student fills out an invalid peer eval with the rubric, they are not able to adjust it. So if a student who is evaluating another student makes a mistake and wants to fix it, they are unable to.  Leaving the student who is receiving the feedback with nothing.
