How do u use blackboard?

You didn't capitalize it, but I ume you mean Blackboard, the online clroom management system, rather than the physical blackboard you write on with chalk? I've used it for a number of my cles for years. I keep the syllabus and outlines of lectures up there. I have given quizzes on it. I've recorded grades on it so that students can see where they stand at any point in the course. I've posted articles and other materials that were for the use of the cl only up there. I've given details of how papers and other ignments were to be done.
