I'm trying out the new course software this semester. It's called Canvas, and here in the Indiana University system it replaces the version of Sakai called Oncourse that we've used for a dozen years or more.
Today I notice that in Canvas the stream of announcements sent by the instructor to students has an optional RSS feed. Students can read the announcements at the Canvas site or have them sent to their email address, or they can read new announcements in an RSS reader. How about that?
And then I see that I can write these announcements in some other piece of software, outside of Canvas, if I wish, and if that software constructs an RSS feed I can have Canvas check the feed for updates and send anything new out to the class as an announcement.
