Acknowledgements

First and foremost I am indebted to my supervisors, Dr. Sandra Cairncross and Dr.Keith Smyth, for their support and endless patience throughout this project. Despite the many delays and unforeseen events over a period that lasted much longer than anyone could have expected, they never failed to listen, guide and encourage. Furthermore, this work could not have been completed without the valuable contributions to the main coding events and subsequent team discussions made by my colleague and friend, Dr. Norrie Brown.

Embarking on this journey was borne out of an idea that turned into much more thanks to the vision and initial support of Prof. Fred Percival, former director of Educational Development at EdinburghNapierUniversity. Prof Percival listened to my questions and recommended I should find the answers-and I think I have, at least some.

The page isn’t long enough to list the additional tasks taken on bycolleagues in Academic Practice and Professional Development during the final stages of this work and I thank them all for putting up with me and shouldering more than their fair share as a result. Finally, with the help and understanding of Dr. Karen Aitchison, Head of Academic Practice, the last hurdle or two could be overcome in order for this research work to be completed.

Thank you.

Abstract

Despite a growing research base in support of higher order thinking processes fostered in asynchronous online dialogue, the research community seems far from a consensus that would unequivocally anchor a higher level of understanding with asynchronous communications technology. Transcripts of online discussion messages provide rich sources of data about a range of communicative issues. Content analysis to date has seen protocols emerge for rate of interaction, critical thinking, collaboration and tutor presence, for example.

The research presented here focuses on depth of understanding as mapped against the SOLO (Structure of the observed learning outcome) taxonomy by Biggs and Collis (1982) which stands out as a content analysis tool as it focuses on structural complexity of text rather than subject specific, manifest content. The taxonomy’s five levels offer a continuum from surface to increasingly deep understanding against which written responses are mapped.A previously published small-scale study in which SOLO was successfully applied in the qualitative content analysis of online discussion transcripts of an environmental science distance education course (Brown, Smyth & Mainka, 2006) prompted the more comprehensivemain investigation reported here.

The SOLO framework was applied to a representative set of data constituting student responses in three constructively aligned, undergraduate physical science distance education courses. Ithas proven to be a robust, replicable and reliable online content analysis tool in a modified format created to includeinteractive levels that takes account of peer-peer and peer-tutor discourse. A simple coding protocol has beendesigned for reuse and further development by researchers and practitioners. In an extended outcome, the significance offormal collaborative opportunities in fully online distance education course design was linked todeeper levels of understanding in the asynchronous discussion which is seen to confirm the role of online collaboration for high quality learning in the distance education context.
