Hola Angel,
El plugin opcional de dedicación al curso le muestra al profesor el tiempo que los alumnos han estado dentro de la plataforma.
Desafortunadamente no está oficialmente aprobado para Moodle 2.7; solamente está disponible para ramas de 2.0 a 2.6. El autor del plugin recientemente escribió:
"The plugin is still compatible with Moodle 2.7. However Moodle has
changed is logging internal system, so the old mdl_log table isn't
filled with new log entries by default. These log entries are needed by
this plugin to calculate course dedication.
To enable "legacy login" go to Plugins -> Logging -> Manage log
stores and ensure that "Legacy log" its enabled. This change will enable
logging only after enabling it, so if your course already started,
course dedication calculations won't be accurate.
In the future we will update the plugin to use these new log system to calculate course dedication."
Valdría la pena investigar esto...
