What is it?
Often before important assignments but also at other times during the semester, some lecturers will answer questions from students via blackboard, Facebook, Twitter or any other suitable online platforms. This is a good way to ensure that answers are available to the whole class as opposed to just a few students and that the feedback stays online after the Q&A session has ended.
How can students make the most of it?
If you don’t feel brave enough to raise your hand during lectures, this is a good way to ask for feedback on a particular point. And remember, there is no stupid question! The chance is, if it is not clear to you, it will not be clear to other students either!
