This document discusses strategies to promote collaborative interactions in an online learning management system. It describes a study of a master's degree program delivered online with some face-to-face sessions. The study examined how students interacted collaboratively on discussion forums and with tutors. Key findings included that students learned to structure discussions into threads over time, tutors guided discussions with pointers rather than enforcing participation, and asynchronous discussions supported reflection. The implications discussed promoting awareness in groups and training students to effectively use collaboration tools.
