Online teaching practices : Sociomaterial matters in higher education settings / Undervisningspraktiker online : Ett sociomateriellt perspektiv på högre utbildningBolldén, Karin January 2015 (has links)
The aim of this study was to describe and analyse online teaching practices in the Swedish higher education context. The study had an online ethnographic approach and was based on empirical data on the teaching in two university courses. The study rested primarily on observational data but interviews and available documents also formed the basis for analysis. Empirical data were analysed with a perspective of practice theory – a perspective within a sociomaterial account. The results showed that online teaching was characterised by an embodied sociomaterial practice. The teacher’s body could be understood as both multiple and closely interwoven with technology. Furthermore, the teacher’s body was used in the teaching situation to reduce technological complexity but also, along with other forms of materiality, to prefigure what kind of teaching would take place. Teacher interventions in online environments could furthermore be understood as relational to both technology (that is the virtual material arrangement) and teachers’ doings and sayings (that is the teaching practice). Teacher interventions were aimed at making the arrangement intelligible for the students. The study showed that teacher interventions arranged both students and information and communication technology (ICT) in order to make them work as a teaching practice. The teaching practice that emerged was characterised as an interplay between virtual materiality and social practice, where asymmetricrelations between teachers and the ICT prevailed. / Syftet med föreliggande studie var att beskriva och analysera undervisningspraktiker online i svensk högre utbildningskontext. Studien har en onlineetnografisk ansats och baseras på empiriska data av undervisningen i två kurser på universitetsnivå. Studien stödjer sig främst på observationsdata men även intervjuer och dokumentstudier ligger som grund för analysen. Empiriska data har analyserats med ett praktikteoretiskt perspektiv – ett perspektiv inom sociomateriell teoribildning. Resultatet visar att undervisning online kännetecknas av en förkroppsligad sociomateriell praktik. Lärarkroppen kan förstås som både multipel och tätt sammanvävd med teknologi. Vidare används lärarkroppen i undervisningssituationen för att reducera komplexitet men även för att, tillsammans med annan materialitet, prefigurera vad det är för typ av undervisning som kommer att utspela sig. Vidare kan lärarinterventioner i onlinemiljöer förstås som relationella till både tekniken (det vill säga det virtuellt materiella arrangemanget) och lärares göranden och säganden (det vill säga undervisningspraktiken). Lärarinterventioner syftar till att göra arrangemanget begripligt för studenterna. Studien visar att lärarinterventionerna arrangerar både studenter och informations- och kommunikationsteknologi (IKT) i syfte att få dem att fungera som en undervisningspraktik. Den undervisningspraktik som uppstår är inte given på förhand utan emergent. Den karaktäriseras av ett samspel mellan virtuell materialitet och social praktik där asymmetriska relationer mellan lärare och IKT råder.

Textmedierade virtuella världar : Narration, perception och kognition / Textually Mediated Virtual Worlds : Narration, perception and cognitionPettersson, Ulf January 2013 (has links)
This thesis synthezises theories from intermedia studies, semiotics, Gestalt psychology, cognitive linguistics, cognitive psychology, cognitive poetics, reader response criticism, narratology and possible worlds-theories adjusted to literary studies. The aim is to provide a transdisciplinary explanatory model of the transaction between text and reader during the reading process resulting in the reader experiencing a mental, virtual world. Departing from Mitchells statement that all media are mixed media, this thesis points to Peirce’s tricotomies of different types of signs and to the relation between representamen (sign), object and interpretant, which states that the interpretant can be developed into a more complex sign, for example from a symbolic to an iconic sign. This is explained in cognitive science by the fact that our perceptions are multimodal. We can easily connect sounds and symbolic signs to images. Our brain is highly active in finding structures and patterns, matching them with structures already stored in memory. Cognitive semantics holds that such structures and schematic mental images form the basis for our understanding of concepts. In cognitive linguistics Lakoff and Johnsons theories of conceptual metaphors show that our bodily experiences are fundamental in thought and language, and that abstract thought is concretized by a metaphorical system grounded in our bodily, spatial experiences. Cognitive science has shown that we build situation models based on what the text describes. These mental models are simultaneously influenced by the reader’s personal world knowledge and earlier experiences. Reader response-theorists emphasize the number of gaps that a text leaves to the reader to fill in, using scripts. Eye tracking research reveals that people use mental imaging both when they are re-describing a previously seen picture and when their re-description is based purely on verbal information about a picture. Mental spaces are small conceptual packets constructed as we think and talk. A story is built up by a large number of such spaces and the viewpoint and focus changes constantly. There are numerous possible combinations and relations of mental spaces. For the reader it is important to separate them as well as to connect them. Mental spaces can also be blended. In their integration network model Fauconnier and Turner describe four types of blending, where the structures of the input spaces are blended in different ways. A similar act of separation and fusion is needed dealing with different diegetic levels and focalizations, the question of who tells and who sees in the text. Ryan uses possible worlds-theories from modal logic to describe fictional worlds as both possible and parallel worlds. While fictional worlds are comparable to possible worlds if seen as mental constructions created within our actual world, they must also be treated as parallel worlds, with their own actual, reference world from which their own logic stems. As readers we must recenter ourselves into this fictional world to be able to deal with states of affairs that are logically impossible in our own actual world. The principle of minimal departure states that during our recentering, we only make the adjustments necessary due to explicit statements in the text.
