An Activity Feed is like a social media feed where an instructor can share information and also have a conversation with students about it. Activity Feed messages allow participants to communicate quickly and less formally than in discussion posts. They are useful for requests for confirmation on a question or topic, an exit ticket after class, an easy poll, or to point students to course assignments or content and allow for their questions or feedback.
The Activity Feed is just below the Announcements. You can update your notification settings to see updates and pin posts to keep important posts “on top.”
