Abstract
This article reports a grounded theory study of the moderation of asynchronous online discussions, to explore the processes by which tutors in higher education decide when and how to moderate. It aims to construct a theory of e‐moderation based on some key factors which appear to influence e‐moderation. It discusses previous research on the definition and practice of e‐moderation, and then describes the study, which involved four e‐moderators working in two different university contexts. Key themes on e‐moderation, which emerged using a grounded theory approach, are discussed. It proposes a framework for e‐moderation and suggests that as a facilitative activity, it should be sufficiently contained within a ring‐fenced learning arena. Factors outside and inside the ring‐fence that appear to influence e‐moderation and their implications for future theory development and validation are discussed.
