    Backchannels and breathing2014In: Proceedings from FONETIK 2014: Stockholm, June 9-11, 2014 / [ed] Mattias Heldner, Stockholm: Department of Linguistics, Stockholm University , 2014, p. 47-52Conference paper (Other academic)
    Abstract [en]

    The present study investigated the timing of backchannel onsets within speaker’s own and dialogue partner’s breathing cycle in two spontaneous conversations in Estonian. Results indicate that backchannels are mainly produced near the beginning, but also in the second half of the speaker’s exhalation phase. A similar tendency was observed in short non-backchannel utterances, indicating that timing of backchannels might be determined by their duration rather than their pragmatic function. By contrast, longer non-backchannel utterances were initiated almost exclusively right at the beginning of the exhalation. As expected, backchannels in the conversation partner’s breathing cycle occurred predominantly towards the end of the exhalation or at the beginning of the inhalation.

    Supporting after action review in simulator mission training: Co-creating visualization concepts for training of fast-jet fighter pilots2019In: The Journal of Defence Modeling and Simulation: Applications, Methodology, Technology, ISSN 1548-5129, E-ISSN 1557-380X, Vol. 16, no 3, p. 219-231Article, review/survey (Refereed)
    Abstract [en]

    This article presents the design and evaluation of visualization concepts supporting After Action Review (AAR) in simulator mission training of fast-jet fighter pilots. The visualization concepts were designed based on three key characteristics of representations: re-representation, graphical constraining, and computational offloading. The visualization concepts represent combined parameters of missile launch and threat range, the former meant to elicit discussions about the prerequisites for launching missiles, and the latter to present details of what threats a certain aircraft is facing at a specific moment. The visualization concepts were designed to: 1) perceptually and cognitively offload mental workload from participants in support of determining relevant situations to discuss; 2) re-represent parameters in a format that facilitates reading-off of crucial information; and 3) graphically constrain plausible interpretations. Through a series of workshop iterations, two visualization concepts were developed and evaluated with 11 pilots and instructors. All pilots were unanimous in their opinion that the visualization concepts should be implemented as part of the AAR. Offloading, in terms of finding interesting events in the dynamic and unique training sessions, was the most important guiding concept, while re-representation and graphical constraining enabled a more structured and grounded collaboration during the AAR.

    Designing for added pedagogical value: A design-based research study of teachers’ educational design with ICT2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    In an increasingly digitized world teachers are expected to take on the role of educational designers and use ICT to design in ways that add pedagogical value to teaching and learning. This thesis adopts a design-based research (DBR) approach to: (a) explore and contribute to the educational design processes of teachers of English as a foreign language in their efforts to use ICT for added pedagogical value, (b) examine how ICT is used in educational designs to create/contribute to what the teachers and students describe as added value and (c) explore, problematize and refine DBR as a research approach.

    Literature studies and a collaborative self-study preceded the DBR to guide its focus and implementation. The DBR was carried out over a period of two years in four upper secondary schools in Sweden in which every student had access to their own computer. The research data consists of: (a) audio recorded design conversations, (b) enacted educational designs and design elements as parts of these, (c) reflective log entries written by the participating teachers, (d) focus group interviews with students and (e) the researcher’s field notes.

    Six different theoretical frameworks and models are used in combination in the accompanying articles to analyze the data and achieve the three research aims. The findings show how teachers’ pedagogical reasoning and TPACK development are interconnected and reciprocal aspects of the educational design process and how the externalization of, and reflection on, these aspects is necessary to develop the specific and practical TPACK needed to realize design intentions in situated contexts. A number of challenges and opportunities in the educational process have been identified.

    Moreover, the findings show how ICT was used to contribute added value in educational designs by facilitating: (a) more authentic and seamless learning experiences in external online contexts with both in-class and out-of-class actors irrespective of time and place, (b) an exchange of digital knowledge representations of understanding and practice between different actors, e.g. for the purposes of modelling, supporting cognitive apprenticeship, meta-cognitive self-regulation and formative assessment and (c) new and extended forms of, and opportunities for, collaborative creation and meaning-making.

    The current common focus in DBR on the development of prescriptive design principles is problematized in relation to the findings of the thesis, which illustrate the complex and situated nature of the educational design process. A theoretically and empirically informed design framework (DF) is developed and used as a conceptual tool to guide and analyze educational design processes and enactments. The findings illustrate how the use of the DF and the process of collaborative design reflection contributed to the analysis of the teachers’ design intentions and de facto design practices and to a DBR format that allowed the participants to use their respective competencies in the development of educational designs for added value. The thesis thereby serves as an example of how DBR can be methodically implemented to study and generate increased knowledge about teachers’ design intentions and design practices, develop research-based educational designs in line with teachers’ pedagogical intentions and support their development as educational designers.
