The Activity Feed is a new option that will be included with this month’s updates. It is a more interactive alternative to the News Feed that allows you to have comments on Messages. This can allow you to discuss the Message right on your Course Homepage. You can also create or link Dropboxes to the Activity Feed. This can allow students to make comments on the Activity Feed if they have questions about the Dropbox.
For more information on how the Activity Feed might be useful in your class, you can read this D2L Article.
