Comparing Role-Playing Activities In Second Life And Face-To-Face Environments, Fei Gao, Jeongmin J. Noh, Matthew J. Koehler

Fei Gao

This study compared student performances in role-playing activities in both a face-to-face (FTF) environment and a virtual 3D environment, Second Life (SL). We found that students produced a similar amount of communication in the two environments, but the communication styles were different. In SL role-playing activities, students took more conversational turns, but have shorter exchanges compared to the FTF environment. Students generated an equal amount of topic-related concepts in the two environments. They also reported role-playing activities in SL as more interesting and less formal. The educational implications for this study are discussed.

Designing Asynchronous Online Discussion Environments: Recent Progress And Possible Future Directions, Fei Gao, Tianyi Zhang, Teresa Franklin

Fei Gao

Asynchronous online discussion environments are important platforms to support learning. Research suggests, however, threaded forums, one of the most popular asynchronous discussion environments, do not often foster productive online discussions naturally. This paper explores how certain properties of threaded forums have affected or constrained the quality of discussions, and argues that developing alternative discussion environments is highly needed to offer better support for asynchronous online communication. Using the Productive Discussion Model developed by Gao, Wang & Sun (2009), we analyzed current work on four types of asynchronous discussion environments that have been developed and researched: constrained environments, visualized environments, anchored …

Leveraging Apple Remote Desktop To Facilitate Classroom Critiques Of Digital Projects, Jerry C. Schnepp Apr 2015

Leveraging Apple Remote Desktop To Facilitate Classroom Critiques Of Digital Projects, Jerry C. Schnepp

Jerry C Schnepp

Classroom critiquing of visual projects is an essential exercise to help students refine their work. Usually, instructors display student work on a large screen so that the class can offer comments and suggestions. However, problems arise because critiques are often mired by ambiguous or misunderstood language. Sometimes students are better shown than told. This presentation demonstrates how Apple Remote Desktop (ARD) can be used to project the display of any lab computer while the instructor and student share control. The student’s work can be interactively modified during a critique session, resulting in an engaging experience for the entire class.
