A Threaded Discussion gives you an opportunity to participate in virtual conversations at any time and any location. Threaded discussion refers to online discussion postings about a topic. In an online course, your professor will have several discussion assignments throughout the semester. Each threaded discussion has a question for students to answer. Students are asked to post their answer on the Discussion Forum assigned to the week, read other students’ posts, and respond to them. This group of messages with the initial message and responses is called a 'thread'. Be sure to follow your professor’s specific instructions, found either in the syllabus or on the Moodle page. 

Here’s an instructional video to give you further help with threaded discussions:
