    A Multimodal Seamless Learning Approach Supported by Mobile Digital Storytelling (mDS)2018Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The use of digital tools such as smartphones, tablets and laptops have shown potential to enhance teaching and learning in a wide variety of contexts. 21st century skills such as creativity, problem-solving and innovation as means for supporting learning and knowledge creation, are considered fundamental proficiencies in today's technology- driven society, and they are therefore considered essential to promote, already from the earliest of school years. Hence, there are a number of challenges related to how to design and implement innovative and varied strategies

    for teaching and learning supported by mobile technologies in educational settings. Moreover, it is also crucial to think about how to actively involve teachers into the processes mentioned above, inspiring and inviting them to implement new methods and technologies into their everyday educational practices.

    The work presented in this thesis embodies a series of co-design and design-based research efforts aiming at exploring the interplay between design, information and communication technologies and learning through mobile digital storytelling, guided by the theoretical frameworks of constructivism, multimodality, new media literacies, mobile seamless learning, and technology enhanced learning. Two main research questions have been identified as formulated below, and have served as

    the basis that guided my efforts:

    What design features are necessary to scaffold mobile seamless learning approaches with the support of mobile digital storytelling?

    Considering the role of mobile digital storytelling for educational settings: which design factors and learning requirements could guide and support similar initiatives?

    Over the years of my doctoral studies, a progression of research interventions involving teachers, pupils, and museum staff have been co-designed, developed, tested and validated. These efforts have resulted in a method, a mobile application, and a web service for mobile digital storytelling in educational contexts, named the mobile digital storytelling (mDS) system.

    The mDS system introduces learning technology approaches aiming to support teacher and pupil digital inclusion, mobile seamless learning and multimodal aspects, and serves as a reflective instrument for both collaborative and individual work. The validation of mDS in different educational settings indicates that it can be independent of subject matter, user age, locality and previous knowledge of technology enhanced learning, and is easy to access and manage for teachers as well as pupils. Hence, it proposes several innovative means on multiple levels for meeting the 21st century skills required for supporting contemporary learning and knowledge creation.

    A teacher-centred design system to integrate digital technologies in secondary mathematics classrooms2018Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    Despite efforts made by teachers and researchers, studies show that digital technologies have not improved conditions for teaching and learning mathematics to the degree expected by stakeholders inside as well as outside the school system.

    In this research, the problem of the integration of digital technologies is addressed through the perspective of design. It sets out to explore the conditions where educational design researchers may succeed in producing valuable and sustainable contributions to teacher change. The design approach developed and used for this purpose is Agile Educational Design (AED). It shares many of the common features of other design methodologies within the field; however, the AED approach is an explicit systems approach to design based on the Singerian philosophy of design. Rather than focus on ready-made products or other resources such as curriculum material, professional development or design principles, the focus is on processes and supporting teachers’ operationalisation of theoretical principles to achieve change. It is argued that all phases of the design process need to be considered from a research perspective. The developmental phases cannot be treated as uncomplicated inputs that only serve as a ‘design base’ for research activities. The Anthropological Theory of the Didactic is used as an overall theoretical framework to describe all aspects of the design process and to analyse the empirical data which consists of three design cycles related to three different ways of interacting with teachers. The design cycles were carried out in various settings, including different schools (secondary level) and with different teachers and different learning objectives. The dynamic geometry software GeoGebra was used in all three cycles.

    The results highlight some of the internal and external constraints that hinder teachers from integrating digital technologies in an effective way to support students learning mathematics. Digital technologies introduce important epistemological changes in the mathematical content that may explain some of the teachers’ difficulties in exploiting the full potential of digital technologies. However, giving teachers the responsibility for orchestrating lessons in accordance with theoretical principles provided by a researcher showed promising results regarding achieving sustainable changes in teachers’ practices.

    Archaeological Challenges, Digital Possibilities: Digital Knowledge Development and Communication in Contract Archaeology2018Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [sv]

    Den här forskningen har studerat digitaliseringen av arkeologin med fokus på svensk uppdragsarkeologi. Målet har varit att öka förståelsen kring hur disciplinen förhåller sig till de förändringar som digitaliseringens innebär och människans roll i dessa processer. Avhandlingen är en studie av digitaliseringens betydelse för de arkeologiska processer som berör kunskapsproduktion och kommunikation. Arbetet problematiserar förståelsen av digitala data inom dessa kontexter men visar också på digitaliseringenspotential och hur arkeologin kan dra nytta av den. Forskningen aktualiserar på nytt det teoretiska angreppssättet reflexivitet i ett digitalt sammanhang och kombinerar detta med kommunikationsteorier i syfte att utmana det arkeologiska arbetsflödet och knyta det närmare dagens samhälle. Resultatet av denna forskning visar på att digital kommunikation baserad på arkeologiskt källmaterial kan vara något mer än förmedling av resultat. Med interaktivt historieberättande finns vägar att skapa emotionella virtuella kopplingar mellan användare och arkeologi som relaterar till nuet och detomgivande samhället. Genom att länka ihop den arkeologiska tolkningsprocessen med kommunikation, skapas möjligheten för kunskapsproduktion att bli kunskapsutveckling.

    Att leda lärande: En vänbok till Per Gerrevall2018Samlingsverk (redaktörskap) (Övrigt vetenskapligt)
    Abstract [sv]

    Leda lärande är en vänbok till professor emeritus Per Gerrevall vid Linnéuniversitetet. Ett tjugotal medverkande kollegor, forskare och lärare tar upp olika aspekter av ledning och ledarskap i olika pedagogiska kontexter och verksamheter. De olika verksamhetsområdena som tematiseras i boken är akademi och högre utbildning, idrottsfältet och de pedagogiska professionerna.

    Kapitlen i boken anknyter till några av de forsknings- och verksamhetsområden som Per arbetat inom under en lång framgångsrik och inspirerande karriär inom akademin. På temat leda lärande ger bokens innehåll olika infallsvinklar på hur pedagogiska praktiker utvecklas och förfinas genom de ställningstaganden och val som framsynta lärare och ledare gör. Det gäller såväl inom högre utbildning, där ledare märker ut frågor, perspektiv och utforskningar inom kunskaps- och forskningsfronterna. Det gäller inom idrottsfältet där de goda och framgångsrika ledarna ser nästa steg i talangens utveckling. Och, det gäller också inom utbildning och skola där den pedagogiska ledaren tillsammans med de studerande märker ut mål och navigerar mot uppsatta mål i de lärandes bildningsgång.

    Bokens olika kapitel ger sammantaget en rik repertoar av nycklar för att leda lärande på ett kvalificerat sätt och för att tackla några av de utmaningar som lärandefrågorna, internationellt och nationellt, står inför i en tid av stora samhälleliga omställningar. Alla med intresse för frågor om ledning, lärande och pedagogik har utbyte av bokens olika kapitel såväl som i professor Per Gerrevalls verk och gärning.

    Att synliggöra det förväntade: förskolans dokumentation i en performativ kultur2018Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The aim of the study is to use the documentation produced and made public in preschool to contribute with knowledge about values in preschool performative documentation practice. The study focuses on seemingly valuable actions in the documentations studied.

    Ball’s performativity concept has been applied to analyze the documentationsthat form the basis of the study. The theoretical concepts of fabrication and second-order activity have been used in the analysis of the material. In addition, core actions within a performative culture characterized by displays, judgements and comparisons form the basis of the analysis. The empirical material consists of documentation produced and made public in preschool bybeing posted on walls and in children’s files.

    Eight categories of valuable actions emerge from the material: actions related to learning and knowledge, social actions, self-control and obedience, independence, creativity and curiosity, ethical actions, participation and influence, as well as joy and wellbeing.

    The result shows that actions related to learning and knowledge form the core in preschool documentation practice. Besides representing an overwhelming majority of the documentation studied, they are also included in other valuable action categories. Actions playing a minor role in the material include ethical actions as well as participation and influence. The focus of learning and knowledge lies mainly on particular subjects or curriculum areas, such as language, mathematics and science. Most documentation also demonstrates a goal and result orientation which indicates the importance of learning and knowledge. The children are the ones made visible in preschool documentation, while teachers are relatively invisible. The documentation focuses on the knowledge and skills of the children. The assessments are made both implicitly, by highlighting certain actions as valued, and explicitly, bytesting children’s knowledge and abilities by check-up tasks or interviews. Comparisons are not normally made between children, but rather bycomparing children’s current knowledge and skills with what they havedemonstrated previously. The majority of the documents lack information onpreschool contributions to improvements in children’s knowledge.

    Performative elements like performance, examination, evaluation, check-ups, goal orientation, result orientation and focus on the individual are most distinctly linked to the category of learning and knowledge. This indicates a connection that may contribute to primarily highlighting learning and knowledge in the documentation. This category includes all the analysis concepts that are used in the study and are relevant in a performative culture. Hence, a strong focus on learning and knowledge is in itself an indication that the documentation practice should be characterized as performative.

    Att tävla för betyg: gymnasieelevers bild av ämnet idrott och hälsa genom bedömningspraktiken2018Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [sv]

    Syftet är att undersöka och förstå hur elever på gymnasienivå uppfattar ämnet idrott och hälsa genom den bedömningspraktik de erfar. Ett delintresse utgörs av innehållet i bedömningspraktiken och vilken bild av ämnet som därigenom framträder. Ett andra delintresse är vad eleverna uppfattar ligger till grund för själva bedömningen. Ett tredje delintresse är riktat mot bedömningspraktiken i stort och på vilka sätt eleverna uppfattar i vad mån denna ger dem likvärdiga förutsättningar att visa vad de kan.

    Elevernas uppfattningar har studerats med hjälp av fokusgruppsintervjuer med inspiration i tre olika vinjetter. I studien deltog 38 elever på fyra olika gymnasieskolor. För att vidare kunna förstå och analysera elevernas uppfattningar användes ett nyinstitutionellt perspektiv där normativa, regulativa och kulturella villkor står i förgrunden (Scott 2008). De regulativa och de normativa villkoren förstås utifrån olika styrdokument och de kulturella villkoren utifrån tidigare forskning om ämnet.

    Analysen visar att den institutionaliserade föreningsidrotten får företräde framför både skolans styrdokument och ett mindre institutionaliserat hälsoområde. Vissa normerande inslag uppfattas som viktiga, speciellt de som kan kopplas till fostrande aspekter så som exempelvis samarbete, hänsyn, förståelse och fair play, medan andra normerande och reglerande villkor negligeras eller nämns inte alls, som exempelvis friluftsliv. Detta skulle kunna förstås som att det framför allt är de kulturella villkoren i form av föreningsidrott som påverkar elevernas uppfattningar om ämnet idrott och hälsa. De intervjuade eleverna uppfattar idrott och hälsa i stora drag som ett orättvist ämne. Det finns de elever som kan ”rätt” idrott och samtidigt finns de som inte har dessa färdigheter och ingen av eleverna uppfattar att de kommer till sin rätt i ämnet.

    Bad Death at Sandby borg: A Bioarchaeological Analysis of Intergroup Violence and Postmortem Agency of Unburied Corpses2018Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The subject of corpses from mass violence is surprisingly unexplored, even though the materiality of the corpse carries strong symbolic capital in conflicts. The aim of my PhD research is to create new knowledge about the implications of unburied corpses that stem from intergroup conflicts, and subsequently to add knowledge concerning how intergroup violence is organised to achieve desired social agendas.

    In the licentiate thesis presented here, I research the conditions for postmortem agency and how treatment of corpses can be studied in prehistory, specifically through the material remains of unburied corpses from the Sandby borg massacre. The Sandby borg case study is explored through a bioarchaeological perspective. Inside the Iron Age ringfort, the remains of at least 26 individuals have been recovered hitherto. Several of the dead display traces of lethal intergroup violence. By integrating osteology, archaeology, taphonomy and social theories, I show how bioarchaeological research can contribute to the understanding of past postmortem agency in relation to intergroup violence as a social process. The thesis is comprised of four articles.

    Benzene-char conversion and particle-vapor characterization in biomass gasification2018Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Biomass is increasingly attracting attention as an alternative to fossil fuels. Gasification permits the thermochemical conversion of biomass into a product gas rich in carbon monoxide and hydrogen. The product gas can be further processed to generate heat, electricity, synthesis gas, chemicals, and biofuels. Particulate matter (PM), inorganic and organic (tars) impurities are formed as contaminants in the gasification process. In this thesis PM and tars formed during atmospheric fluidized bed biomass gasification are characterized and the conversion of a model tar compound (benzene) using a biomass based char aerosol in high temperature (HT) applications is investigated.

    PM in the product gas of a steam-blown atmospheric bubbling fluidized bed gasifier was characterized for mass size distribution and concentration, morphology, and elemental composition. The hot product gas was extracted using a HT- dilution probe combined with a primary and a secondary thermodenuder to adsorb tars and investigate the volatility/thermal stability of the remaining aerosol, respectively. Size distributions with three distinct modes were established. The fine and intermediate modes were mainly formed by tar and alkali vapors that had condensed in the sampling and conditioning systems. The coarse mode mainly consisted of the original particles, which are char, fly ash, and fragmented bed material. The presented PM sampling and conditioning system also showed the potential for online monitoring of heavy tars.

    The tar conversion performance of finely dispersed char particles within a HT-filter and an Al2O3 bed were tested experimentally using benzene as the model-tar. Benzene plus steam (or CO2) were simultaneously supplied to a tubular ceramic reactor that was heated electrically. Fragmented char particles were suspended and continuously supplied via a separate supply line. A HT-filter or a packed bed of crushed Al2O3 balls was positioned in the reactor to retain the char particles. The benzene conversion in the so formed hot char bed was investigated by varying the temperature of the filter or bed, gas flow rates, benzene concentrations, gasification media, char type, char mass and char concentration.

    Increasing the ratio of the char mass and gas flow rate (also referred to as char weight time) enhanced the benzene conversion. This was accomplished by increasing the supplied char concentrations, reducing the gas flow rates or slowing the char gasification reactions. The latter was achieved by lowering the steam concentrations or changing the gasification medium from steam to CO2. Increasing the temperature of the Al2O3 bed did not only raise the char gasification rate and thus reduce the char weight time but also showed to enhance the specific benzene conversion activity of the woody char samples. However, in the 900−1100 °C temperature range, the combined effect was to lower benzene conversions at higher temperatures. The apparent rate constant of the benzene conversion was slightly higher when CO2 rather than steam was used as the gasification medium. Increasing the benzene concentration slightly reduced the benzene conversion. Activated carbon pellets showed higher benzene conversions compared to a pine wood char which was related to the higher specific surface area of the activated carbon pellets. In contrast to a commercially available barbeque charcoal made from broadleaf wood, steam-activated woody charcoal converted benzene even in the absence of steam. This was probably due to the earlier steam activation of the woody charcoal and thus higher microporous surface area compared with that of the barbeque charcoal. Doping the woody barbeque charcoal with approximately 0.7 wt. % iron or 2 wt. % potassium did not improve the specific benzene conversion of the char. For a certain char concentration, however, the doping increased the char gasification rate, leaving less char in the packed alumina bed, thus leading to overall lower benzene conversions.

    Black Lives, White Quotation Marks: Textual Constructions of Selfhood in South African Multivoiced Life Writing2018Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    This thesis focuses on South African multivoiced and collaborative life writing. The analysed primary texts are The Long Journey of Poppie Nongena (1980) by Elsa Joubert, The Calling of Katie Makanya: A Memoir of South Africa (1995) by Margaret McCord, Finding Mr Madini (1999) by Jonathan Morgan and the Great African Spiderwriters, David’s Story (2000) by Zoë Wicomb, and There Was This Goat: Investigating the Truth Commission Testimony of Notrose Nobomvu Konile (2009), co-written by Antjie Krog, Nosisi Mpolweni and Kopano Ratele. All of these primary texts are either collaborative autobiographies about black lives, multivoiced life writing texts about black lives, or a text that problematises this kind of life writing where predominantly disadvantaged, black life writing subjects either have had their lives narrated or have had their narration steered by well educated, advantaged, Westernised and usually white writers.

    The analyses of the primary texts are carried out by problematising them in the light of the South African historical and cultural context within which they were produced. The focus of the analyses is on the effects on and the consequences for textual constructions of selfhood when the writers tell or include the life writing subjects’ lives in the life writing texts. The involvement of the writers in the life writing projects is argued to greatly have impacted the textually represented selves that were created in the resulting multivoiced life writing texts.

    Drawing on theory rooted in postcolonial studies, life writing in general, and self-narration in particular, this thesis concludes that the examined black South African life narratives to various extents are told on white, Western terms and thus inserted in white quotation marks. White quotation marks are defined in this thesis as a certain Western perception of self-narration and selfhood, consisting of components rooted in language, racial tropes, narrative form, and Western autobiographical traditions. Both writers and life writing subjects have been involved in creating or employing these white quotation marks. In some cases this has been an unintentional result and in other cases it has been a conscious effort.
