  1. 16. When mathematics teachers focus discussions on slope : Swedish upper secondary teachers in a professional development initiative

    Författare :Anna Bengtsson; Constanta Olteanu; Kirsti Hemmi; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; teacher professional development; upper secondary mathematics teachers; collegiality; slope; rate of change; teaching culture; community of practice; learning study; Mathematical Education; Matematikdidaktik;

    Sammanfattning : The shift towards collegiality is a new setting for many teachers. Most teachers work alone, in isolation from their colleagues and collegial collaboration requires organisational structures. LÄS MER

  3. 17. The Problem of Formulating Design Problems : A Typology of Design Briefs

    Författare :Juan Felipe Ruiz Muñoz; Renee Wever; Marie Bengtsson; Matteo Vignoli; Linköpings universitet; []
    Nyckelord :HUMANIORA; HUMANITIES;

    Sammanfattning : It is common for a design team to be handed a problem to solve for others. The handing over is normally referred to as a ‘briefing’ process, and the documentation of the starting point and what is to be done is known as a ‘brief’. It is known that the way we frame and understand a problem influences what paths we see to potential solutions. LÄS MER

  4. 18. Time-Resolved X-ray Diffraction Studies of Laser-Induced Dynamics in Solids

    Författare :Åsa Bengtsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time-resolved X-ray diffraction; ultrafast; phonons; pressure wave; Non-thermal melting; Fysicumarkivet A:2022:Bengtsson;

    Sammanfattning : X-ray diffraction is an invaluable tool in the field of structural dynamics. In the work described in this thesis, time-resolved X-ray diffraction experiments were carried out to investigate ultrafast lattice dynamics. LÄS MER

  5. 19. Material and technique development for ultrasound optical tomography using spectral hole burning filters

    Författare :Alexander Bengtsson; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biomedical imaging; ultrasound optical tomography; acousto-optical tomography; rare-earth-ion doped crystals; spectral holeburning; slow light filters; Tm 3:LaF3; Fysicumarkivet A:2022:Bengtsson;

    Sammanfattning : The molecular sensitivity provided by optical photons has potential advantages in medical diagnostics, for example, in distinguishing healthy from cancerous tissue. However, scattering resulting from inhomogeneities in the refractive index of tissues prevents spatially resolved optical measurements in biological material, except at very shallow depths. LÄS MER

  7. 20. Sociala konstruktioner i förskolans planeringssamtal : I en landsgränsnära förskola

    Författare :Emma Nilsson; Carin Roos; Karin Bengtsson; Maria Simonsson; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Förskola; förskolepersonal; planeringssamtal; gräns; landsgräns; sociala konstruktioner; Pedagogiskt arbete; Educational Work;

    Sammanfattning : The overall aim of this study is to describe the preschool setting that is constructed in the preschool teacher’s planning conversations with a special focus on the border context in which this particular preschool is located. In what ways are the geographic location noticeable and what conceptions are established in their conversations? The study has a social constructivist approach and is informed by borderland theory which means that the focus is on the context and the participants in this context. LÄS MER
