Blackboard easily allows instructors to change from a “regular” discussion forum to a “post-first” (before students have posted, obviously).
The post-first option was possible in ANGEL, too, but I think under-used. Its advantages are that it forces students to create an original post (called a thread in Blackboard) before they can reply to anyone else. They can’t see anyone’s post prior to posting themselves.
To modify an existing forum or create a new one, first go to Course Tools > Discussion Board and then either edit an existing forum or create a new one.
From the edit settings for a forum, scroll to the Forum Settings area and select “Participants must create a thread in order to view other threads in this forum.”
