Much of the published discussion and research on blogs and teaching and learning in higher education focuses on evaluation of blogging as a communicative technique. This type of discussion largely assumes that successful integration of blogging into course delivery should be judged against a pre-existing and unchallenged pedagogical model. This paper argues that to leverage its full educational potential blogging must be understood not just as an isolated phenomena, but as part of a broad palette of cybercultural practices which provide us with new ways of doing and thinking. The paper looks at the ways broader theoretical models associated with the development of the blogosphere might challenge or enhance current theories of teaching and learning. Spatial metaphors inherent in network models of blogging will be contrasted with the surface/depth model of student learning. The paper will argue that blogs should not be seen merely as a technological tool for teaching and learning but as a situated practice that must be brought into appropriate alignment with particular pedagogical and disciplinary practices. A model of blogging as a networked approach to learning suggests that blogging might achieve best results across the curriculum not through isolated use in individual units.
