What is Communication Modality

This chapter reports on an exploratory case study investigating strategies to facilitate group discussions in Second Life, a three-dimensional virtual world. The purpose was to identify best practices for discussion facilitation in-world from the perspective of a virtual host and a discussion facilitator. A host and a facilitator moderated four virtual group discussions with 16 in-service teachers enrolled in a graduate technology class. The chapter discusses several themes that emerged from the host's and the facilitator's debriefings. Key themes include the need for a careful selection of the communication modality (text or voice or a combination), strategies to promote interactivity among the participants, the critical need for at least one facilitator in addition to the host, the need for clear ground rules for the participants, and clear guidelines for the host and the facilitator. Several challenges experienced during the process of facilitating these virtual events are discussed and recommendations are made to address these difficulties. This chapter is of interest to educators who are planning to substitute in-class group discussions with synchronous group discussions in-world.
