Journal article (peer-reviewed)abstract
- Many real-life situations require flexible behavior in changing environments. Evidence suggests that anticipation of conflict or task difficulty results in behavioral and neural allocation of task-relevant resources. Here we used a high- and low-interference version of an item-recognition task to examine the neurobehavioral underpinnings of context-sensitive adjustment in working memory (WM). We hypothesized that task environments that included high-interference trials would require participants to allocate neurocognitive resources to adjust to the more demanding task context. The results of two independent behavioral experiments showed enhanced WM performance in the high-interference context, which indicated that a high-interference context improves performance on non-interference trials. A third behavioral experiment showed that when WM load was increased, this effect was no longer significant. Neuroimaging results further showed greater engagement of inferior frontal gyrus, striatum, parietal cortex, hippocampus, and midbrain in participants performing the task in the high- than in the low-interference context. This effect could arise from an active or dormant mode of anticipation that seems to engage fronto-striatal and midbrain regions to flexibly adjust resources to task demands. Our results extend the model of conflict adaptation beyond trial-to-trial adjustments by showing that a high interference context affects both behavioral and biological aspects of cognition.

In: Learning, Culture and Social Interaction. - : Elsevier BV. - 2210-6561 .- 2210-657X. ; 2:3, s. 127-142

Journal article (peer-reviewed)abstract
- The empirical study presented here focuses upon naturalistic social interaction in online synchronous communities within higher education. Our interests here relate to accounting for the communicative strategies employed by participants who are dealing with a common task, and how these specific tasks are negotiated within the constraints and opportunities accorded in the multimodal multilingual virtual setting. Taking sociocultural theoretical points of departure, we focus on students' languaging and use of tools when they have access to a range of resources inside the online videoconferencing program. The study is based upon screen recordings of both student-only and teacher-lead meetings during one semester in the online course Italian for beginners offered by a Swedish university. The analysis is two-fold: we provide an overview of the interactional patterns at the general lesson level in the data complemented by a micro-interactional analysis of selected slices of everyday life from two meetings. Our findings indicate that students make use of several resources that dialectically shape how they get positioned within the virtual community culture. These identification processes function as ways of enriching and nurturing learning, both of appropriating the target language, as well as enabling ways of being in multimodal, multilingual communities of practices.

Mapping Languaging in Digital Spaces : Literacy Practices at Borderlands
- 2016
-
In: Language Learning & Technology. - Honolulu : University of Hawaii * National Foreign Language Resource Center. - 1094-3501. ; 20:3, s. 80-106
-
Journal article (peer-reviewed)abstract
- The study presented in this article explores the ways in which discursive-technologies shape interaction in digitally-mediated educational settings in terms of affordances and constraints for the participants. Our multi-scale sociocultural-dialogical analysis of the interactional order in the online sessions of an Italian for Beginners language course provided by a university in Sweden is illustrated in terms of an Introduction phase, a Language and Grammar phase, a Discussion phase, and a Concluding phase. Dimensions of TimeSpace shape the organization of the lessons where a range of literacy practices can be identified. A second step in the analysis zooms into the Discussion phase. Taking the concepts of epistemic engine and epistemic domains as points of departure, we explain how the written word shapes the interactional order in online settings. This study highlights how different interactional orders allow for the opening up of new socialization spaces, in which students are more likely to be prevented from getting trapped in their own script of task-oriented activities. Here, participants' cultural processes are complexly layered in digitally-mediated encounters, where their focused orientation towards a variety of offline and online oral and written resources is partly curtailed by the digital environment itself.

Understanding glocal learning spaces : an empirical study of languaging and transmigrant positions in the virtual classroom
- 2014
-
In: Learning, Media & Technology. - : Informa UK Limited. - 1743-9884 .- 1743-9892. ; 39:4, s. 468-487
-
Journal article (peer-reviewed)abstract
- The use of digital tools like computers and tablets in institutional learning arenas give rise to forms of flexibility where time and space boundaries become diffuse. Online learning sites are understood as being crucial today, especially in large parts of the Global North, where anyone anywhere potentially can become a student and have access to educational opportunities. This study focuses on the analysis of recorded sessions, part of an “Italian for (adult) beginners” online course. Our interests relate to accounting for how students negotiate different language varieties, including modalities, and how communication in virtual learning settings enables both flexible participation trajectories and identity positions in and across the boundaries of time and space.The sociocultural and dialogical analyses here are framed in terms of fluidity of “glocal” positions and (trans)languaging that emerge in and across time and space in Technology Mediated Communication. Our findings suggest that online environments support meaning-making where it is possible to identify alternative ways of (co)constructing and mediating learning. Such hybridity as well as the performative character of learning and identity display have important implications for online glocal communities.

Languaging in virtual learning sites : studies of online encounters in the language-focused classroom

Doctoral thesis (other academic/artistic)abstract
- This thesis focuses upon a series of empirical studies which examine communication and learning in online glocal communities within higher education in Sweden. A recurring theme in the theoretical framework deals with issues of languaging in virtual multimodal environments as well as the making of identity and negotiation of meaning in these settings; analyzing the activity, what people do, in contraposition to the study of how people talk about their activity. The studies arise from netnographic work during two online Italian for Beginners courses offered by a Swedish university. Microanalyses of the interactions occurring through multimodal video-conferencing software are amplified by the study of the courses’ organisation of space and time and have allowed for the identification of communicative strategies and interactional patterns in virtual learning sites when participants communicate in a language variety with which they have a limited experience.The findings from the four studies included in the thesis indicate that students who are part of institutional virtual higher educational settings make use of several resources in order to perform their identity positions inside the group as a way to enrich and nurture the process of communication and learning in this online glocal community. The sociocultural dialogical analyses also shed light on the ways in which participants gathering in discursive technological spaces benefit from the opportunity to go to class without commuting to the physical building of the institution providing the course. This identity position is, thus, both experienced by participants in interaction, and also afforded by the ‘spaceless’ nature of the online environment.

Journal article (peer-reviewed)abstract
- Participation as a pedagogy and democratic value turns out to be a critical element in students’ completion of school. Completed education is a regional development project in which a survey has been conducted in order to identify successful strategies to promote completed education in school. In an analysis, in the context of the survey, with an emphasis on school and participation as a pedagogy and democratic value, several findings are shown. It turns out that the importance of participation manifests itself through an emphasis on the societal and democratic mission of school; school ethos; the value praxis of school; pedagogical approach; and viewing the pupil as capable. It is, in more detail, shown that it is particularly crucial to understand the completion of school as a pedagogical problem; create sustainable institutional structures not bound to one person; and to make sure that students are participants in their own studies.

Political Participation as Public Pedagogy : The Educational Situation in Young People’s Political Conversations in Social Media
- 2014
-
In: Journal of Social Science Education. - Bielefeld : Bielefeld University. - 1618-5293. ; 13:4, s. 115-126
-
Journal article (peer-reviewed)abstract
- In this article we argue that young people’s political participation in the social media can be considered ‘public pedagogy’. The argument builds on a previous empirical analysis of a Swedish net community called Black Heart. Theoretically, the article is based on a particular notion of public pedagogy, education and Hannah Arendt’s expressive agonism. The political participation that takes place in the net community builds up an educational situation that involves central characteristics: communication, community building, a strong content focus and content production, argumentation and rule following. These characteristics pave the way for young people’s public voicing, experiencing, preferences and political interests that guide their everyday political life and learning – a phenomenon that we understand as a form of public pedagogy.

Text som kontext – rum, plats och text som social situation

Journal article (peer-reviewed)abstract
- The ability to express oneself in text has come to be an even more pressuring task due to new media. The use of text in the new media and the school looks slightly different and create different claims on which kind of text activity that are advocated. Language activity and use of text in different spaces and places has become a constituent principle in the western society of today – language and the use of text is seen as the ontological condition for social life. The historical and conventional media notion of public and reception has been replaced by a more complex communication situation due to the digital media. Related to this context and the linguistic turn, three concepts; text action, text conversation and the pedagogy of place are developed and exemplified by a national net community. The theoretical contribution makes it possible to understand and approach the use of text and the complexity this use in different spaces and places articulates. The national net community is discussed in relation to the school exemplifying two different public spaces where new media is put forward illustrating a social situation consti-tuted of text – young people’s use of text practically becomes context. How can we understand and approach this new educational situation?
