DISCUSSION is basically the same as the course discussion tab, but this module element is limited to the specific course item to where it is added. This way you create an arena for interaction between the students within the subject of the specific item, not just for the course in general. 


Choose a TITLE for the module even when you will not show it in the unit view. This makes it easier to find the discussion if you want to go back to edit it later. 


REQUIRED urges the student to respond in the discussion. 


This is what module discussion looks like for the students in the course:



NOTIFICATIONS

The option of receiving e-mail when other students post or reply.
