This paper uses Conversation Analysis to investigate the ways in which participants in an online asynchronous postgraduate reading group managed and negotiated their contributions within the discussion. Using the conversation analytic concerns with sequential organisation, adjacency pairs and topicality, this article shows the analytic insights that this perspective can bring to the examination of written asynchronous discourse. The paper shows that in the section of the discussion analysed here, the discourse displayed remarkable similarities to the ways in which face-to-face conversation has been seen to operate in terms of the organisation of conversational turns, the application of specific interactional rights, the lineal development of topics of conversation and the structural use of question-answer turn pairs. The paper concludes by showing how this form of analysis can relate to the formation of reflexive pedagogy in which course design can be created to take account of such findings. It shows how a detailed understanding of how pedagogy is played out in interaction is fundamental for reflecting on the relationship between pedagogic aims and educational practice.

This paper reviews research on learner and tutor interaction in asynchronous computer-mediated (ACM) conferences used in distance learning. The authors note claims made for the potential of ACM conferences to promote higher-order critical inquiry and the social construction of knowledge, and argue that there is a general lack of evidence regarding the actual achievement of these aims in such conferences. We present and discuss the relevant research literature currently available on the effects of social presence, the tutor's teaching and moderating strategies, and task type. The paper concludes with recommendations for future research in each of these areas. (Contains 4 tables.)

This article examines the structure of topic movement within face-to-face postgraduate university seminar discussion forums through a conversation analytic approach. The analysis of 12 audio recordings of seminars showed that in spite of clear differences in the management style of sessions by seminar leaders there were important consistencies in their normative structure of participation. Previous research has shown that the turn-taking procedures used as a basic organisational feature of the talk have been seen to result in a regular change of topic within seminars. Although the research here supports these findings, the data showed that topic change was only one aspect of the topic negotiation process. The analysis in this article illustrates that topic negotiation was an ever-present feature of the talk and that, in addition to frequent "successful" changes of topic, there were also innumerable "unsuccessful" topical interjections. One prominent source of such failure was the presence of overlap in the seminar talk. In addition to being of value to educationalists wishing to understand educational processes, this analysis is viewed as having significant relevance for the development of alternative distributed media for hosting interactive seminars as it shows the implications of the interactional "affordances" of learning environments for the achievement of interactive talk. This article suggests, therefore, that research and development in this field would benefit from detailed studies of the affordances of these alternative hosting media.
