Thu, April 8, 4:00 to 5:00pm EDT (4:00 to 5:00pm EDT), SIG Sessions, SIG-Design and Technology Poster Sessions


Social presence is critical to the interaction in online discussion. But it is unclear how students may develop their social network interaction and how social presence may relate to network interaction development. This study empirically investigated how various aspects of students’ prominence in the social network development of online discussion changed over time and how social presence moderated the above trend over time. This study found that students’ prominence in the social network interaction of online discussion did not improve over time. Furthermore, the flat trend of betweenness, eigenvector, and PageRank, and the downward trend of closeness could be generalized to the participants with different levels of social presence.
