I am testing the LMS called "Canvas," and I saw a feature that made me wonder about Moodle.
In the Canvas forums, people are able to mark which specific posts they have read or not read. They do this by clicking a little circle (see graphic). This is similar to what I see in Mac Mail (see second graphic). This made me wonder how students using moodle keep track of what they have read or not read. As far as I know, Moodle doesn't do this. But am I missing something?
I do know that Moodle changes the color of the subject line for posts that are still within the author's editing time.
I wonder if this "marking" of read posts has ever been discussed, and if there might be a Feature Request for it in the Moodle Tracker system.
As the instructor, I can keep track of what I have read by the way I grade each post.
Incidentally, Moodle seems to be the only LMS (among Blackboard, Desire2Learn, and Canvas) that provides the instructor the ability to grade forum posts "in context," what I find to be an extremely powerful feature.
