How do I use the Course Activity Stream?
The Course Activity Stream shows you all of the recent activity from a single course including announcements, discussions, assignments, and conversations. This stream is different from the Global Activity Stream, which you see in the User Dashboard when you first log in to Canvas.
Note: If your Course Home Page is already set to view the course stream, the View Course Stream link does not appear in the course sidebar.
Open Course Activity Stream
View Course Activity Stream
When viewing the course stream, you can view all recent notifications in the course, including announcements, discussions, assignments, and conversations. This activity stream helps you see all recent activity in your course and easily ask questions and post to discussion forums.
You can manage Recent Activity in a course the same way you can on the User Dashboard. Activities are indicated by activity type and display an icon  for the activity. New or unread activities are shown by a blue indicator dot next to the notification. Recent Activity items remain for four weeks.
You can view the details of each activity by hovering in the notification area and clicking the Show More link .
