Your course instructors will include discussion boards in your course D2L site for several reasons.
The most common purposes for discussion boards are to provide a place where students can:
ask questions about the course topics and assignments
find important announcements
discussion forums on course topics that are part of your assigned work and are assessed for course marks.
For discussion boards or forums that are part of your course assignments, you will need to carefully review all requirements for your participation.
It is important to remember that discussion board posts are formal writing assignments and you will need to organize your ideas,check your writing, and cite any sources that you may use to support your ideas.
