In my institution, several professors are enthousiastic while using the peer review worshop module. We find the possibilities of this module very impressive especifically the possibility to grade the grading process.
We had a search about the grading algorithms because we wanna give explanations about it to students. We wanna use the accumulative evaluation that is described by the following formula :
In this formula, the grade is computed based on a ratio composed of
- the grade given by the student for one criteria as numerator;
- the maximum grade given by all students for that criteria as denominator.
We think such ratio will encourage students to give high scores (while giving 100% to all peers ensures them to have 100% as evaluators).
Intuitively, we would prefer de denominator to be the mean or median grade among all students given grades.
What do you think about it ?
Is there a scientific justification for the choice of the maximum value ?
Are there other options for this formula based on scientific argumentation ?
Finally, if we wanna tune the formula, in which file do we have to make the change ?
Thanks in advance for answer,
