I need a module that allows me to quantify the number of participations made by forum for each student of the discipline.
I use the latest version of moodle.
Hello. I suggest you look at the course Participation report (click that link)
I will just move your post to the Analytics and Reporting forum as it will be more suited to there.
Configurable reports and ad hoc reporting do a fine job of displaying this information. IntelliBoard may also assist with this - it has a free Level 0 version.
