This study attempts to make inferences about the mechanisms that drive network change over time. It adopts simulation investigation for empirical network analysis to examine the patterns and evolution of relationships formed in the context of a massive open online course (MOOC) discussion forum. Four network effects--"homophily,"…

The current study hypothesized that integrating partly observational learning into virtual reality training systems (VRTS) can enhance training efficiency for procedural tasks. A common approach in designing VRTS is the enactive approach, which stresses the importance of physical actions within the environment to enhance perception and improve…

This article provides an account of my experience of immersion as a third-level teacher into the three-dimensional multi-user virtual world Second Life for research purposes. An ethnographic methodology was employed. Three stages in this journey are identified: separation, transition and transformation. In presenting this journey of immersion, it…
