This roundtable discussion is intended for instructors who teach, or are interested in teaching, online classes with a collaborative learning component. Encouraging teamwork in an online class increases peer engagement and decreases the sense of isolation commonly associated with online learning. We will discuss different types of online activities that involve group work, several technologies that enable (or hinder) collaborative learning, and various methods to encourage student interactions in group projects. Participants are encouraged to share their own experience as we discuss collaborative learning techniques for courses ranging from intro-level gen eds to upper-level classes.
