Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- As digital technology is becoming increasingly more common in the classrooms, students are creating screen-based texts that incorporate various modalities. Previous studies show that even if students’ texts are multimodal, the complexity in multimodal text composition are not the subject to established assessment practices privileging verbal and written language. Assessment practices signal which knowledge is legitimate and influence how teaching is organized. How teachers acknowledge and assess multimodal aspects and how practice development in this matter can be supported thereby becomes important issues to address.This study was conducted within the project Digital Arenas in Literacy Practices in Early Primary School (DILS) where teachers from three classes in different schools worked together in workshops to develop literacy teaching. The empirical material consists primarily of the participating teachers written assessments of student texts, before and after an intervention where the teachers were introduced to multimodal perspectives and concepts for analyzing and assessing multimodal texts. The text material was further complemented by video-recordings of this workshop and the teachers’ discussions. Exploring how the teachers understanding of students’ multimodal texts is manifested in their assessments, the study highlights the challenges education and teachers face. The results shows how a lack of a meta-language to describe quality and development in multimodal text-composing results in assessments influenced by established assement practices focusing formal language aspects. Access to such meta-language provided more focus on the use, balance and interrelations of modalities for communicative effect. The implications of what knowledge and practices that are made available to teachers are discussed, and further research on how to implement multimodal assessment practices in the pedagogical practice is suggested.

Being Multisituated : Characterizing laptoping in networked situations
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- During the last 30 years mobile IT has gone from being an exotic ingredient to an everyday artifact. This thesis presents an ethnographic study of laptop use in a university setting. The thesis concludes that it is no longer enough to describe the use of portable IT as an activity in its own right, i.e. using a laptop computer as an activity similar to reading a book or writing an essay. Additionally, describing a person as merely a user of digital technology fails to capture the intervowennessbetween the technology, situation, person and other actors. In order to find more nuanced answers about laptop use the thesis discuss what characterize the use of laptops in everyday life. With support from Actor-Network Theory, the Interaction Order and Experiential computing the thesis explores the hybrid combination of a person-laptop. The contribution is a framework of the driving forces behind the laptoper’s everyday activities. Additionally a model of the networked situation is presented, that uncovers the effects of the laptoper over time, that is, the laptoping process. The contribution is a framework with key characteristics and typified interactions where the multisituated and network dimensions are understood as fundamental elements of hybrid interaction.

Weld Pool Simulations
- 2008
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This investigation is devoted to the study of welding and its effect on the workpiece, focusing on the thermo and fluid dynamical phenomena occuring during a autogenous or nonautogenous arc fusion welding process. Its aim is to simulate the behaviour of the weld pool and analyze the consequence of the solid-liquid phase change, thus obtaining a methodology for predicting the appearance of weld defects related to solidification and cooling. In order to accomplish this, we solve equations governing a number of continuum mechanical and electromagnetical quantities, as well as consider the motion of the freely moving boundary of the weld pool. Since the state of these quantities is strongly influenced by phenomena such as arc and droplet impingement, non-isothermal phase change, surface tension, Marangoni forces and Lorentz forces, much effort is necessarily devoted to the modelling of the corresponding fluxes and sources, as well as to the implementation of computationally efficient techniques for simulating the geometrical deformation of the workpiece, which in our setting is entirely determined by the motion of the weld pool surface.Common to all arc fusion welding processes is the employment of a welding arc. Many techniques rely on the arc to clean and shield the workpiece during the process, however in this study we consider it to be its main purpose to cause the local increase of thermal energy that is required for the establishment of the weld pool, and also to exert the mechanical forces that provoke the subsequent fluid flow which enhances heat transfer and facilitates weld penetration. The physics of the welding arc itself is quite intricate, and although the modelling of the arc is not the prime objective of this research project, we conclude that arc forces act on the pool surface, and that the investigation of the arc behaviour is important insofar that it provides input to the pool model and thus enables a more accurate prediction of the quality of the weldment that is created once the pool has solidified

- Recent development in self-monitoring devices indicates that using quantified data in clinical practicesupporting chronic diseases management holds a big potential. However, exploration of this design space also suggests that some unattended challenges still exist, such as a low adoption rate of self-monitoring tools in existing clinical practice. In this text, wetherefore focus on the ways healthcare professionalsuse quantified data in their practice. We draw onempirical data from an ethnographic study of a cancer rehabilitation center. Our preliminary findings suggestthat the self-monitoring tool supported the nurses'work because it became a functional complement totheir work by allowing them to appropriate the deviceto their and the patients' needs.
