e-Moderating: the key to teaching and learning online (2nd edn) Gilly Salmon, 2004 London, RoutledgeFalmer £23.99 (pbk), 256 pp. ISBN 0 415 33543 4 (hbk), 0 415 33544 2 (pbk)This is a practical guide for e-moderators, whether they are experienced or are new to the online environment, to facilitate skillfully in an online learning environment. Salmon highlights an overview of their roles and the qualities and expertise required in an online teaching and learning environment. Of particular interest throughout this text are the clear and concise presentations of concepts, case studies and illustrations and, in particular, the language used is simple but engaging. In this edition Salmon provides a comprehensive treatment of e-moderating skills, managing e-moderating and online participants and future scenarios for online learning.Based on her years of action research, Salmon developed a five stage e-moderating model (Salmon, 2000) for teaching and learning through online computer mediated conferencing (CMC). The five stages are:• access and motivation; • online socialization; • information giving and receiving; • knowledge construction; • development. Figure 1.

The model provides a roadmap for e-moderators, whether they are new to online learning or are looking for ways to refine their online facilitation skills. The model encourages e-moderators to be more aware of the social and cognitive aspects of online learning and communication, when and how to provide support for the participants, as well as effective practices to facilitate participants in their online learning journey. As described in this model, online learners also master certain technical skills while they progress through the various stages and gradually become more familiar with non-threatening peer-peer and peertutor interactions in the online environment. Using the five stage model the e-moderators facilitate the online learners by:
