Discourse and network analyses of learning conversations

Analytical frameworks for examining educational computer mediated discourse have been mainly designed for asynchronous discussions; hence the classification schemes are typically more sensitive when applied to longer postings than the shorter more condensed exchanges present in online synchronous discourse. This chapter introduces the exchange structure analysis framework for examining online synchronous interaction at levels of structural organisation and pragmatic intention. The further application of social network analysis as a method and visualisation tool for the coded exchanges are explained and illustrated. Examples are provided from transcript data of moderated collaborative group discussions during virtual tutorials in a case study. With the integration of discourse and social network analytical methods, a richer interpretation is gained on the processes of articulation and negotiation of meaning during online learning conversations
