Hello,

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 :

http://docs.moodle.org/dev/Workshop_2.0_specification#Accumulative

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,

Zabelle
