The document discusses best practices for using threaded discussions in online and hybrid classes. Some key points include: - Threaded discussions allow for asynchronous student interaction through posting messages on discussion boards in a hierarchical, topic-based format. - Effective discussions require good topics that are narrow, organized, and keyed to other class activities. Facilitation from the instructor is important to build on student responses. - Asynchronous discussions provide benefits like time and space flexibility for students as well as a permanent record of the conversation, but they also have disadvantages like lack of nonverbal cues, fragmented discussions, and potential delays in interaction. - Instructors can promote use of discussions by making them required and graded components
