  1. 1. Matematikproblem i skolan : för att skapa tillfällen till lärande

    Författare :Eva Taflin; Johan Lithner; Ole Björkqvist; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; problem-solving; rich problem; teacher; instruction; learning; mathematical ideas; occasions; MATHEMATICS; MATEMATIK;

    Sammanfattning : The general purpose of this dissertation is to define and explore what mathematical problem solving entails. Seven criteria for rich problems will also be formulated. Rich problems are defined as problems which are especially constructed for mathematics education in a school context. LÄS MER

  3. 2. En problematisering av ungdomars intresse för naturvetenskap och teknik i skola och samhälle : Innehåll, medierna och utbildningens funktion

    Författare :Anders Jidesjö; Helge Strömdahl; Jari Lavonen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Science and technology are important parts of culture. Thus today there is a need for a science education which promotes ‘science for all’ and ‘scientific literacy’ in order to prepare students for citizenship. Earlier studies indicate that many students find it hard to learn science and technology in school. LÄS MER

  4. 3. Theoretical calculations of heavy atom effects in magnetic resonance spectroscopy

    Författare :Corneliu I. Oprea; Hans Ågren; Patrik Norman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nuclear spin-spin coupling tensor; nuclear shielding tensor; heavy atom effect; hyperfine coupling tensor; restricted-unrestricted approach; Theoretical chemistry; Teoretisk kemi;

    Sammanfattning : This thesis presents quantum chemical calculations, applications of the response function formalism recently implemented within the framework of density functional theory (DFT) by our research group. The purpose of the calculations is to assess the performance of this perturbative approach to determining heavy atom effects on magnetic resonance parameters. LÄS MER

  5. 4. Use of Digital Technologies in Education : The Complexity of Teachers' Everyday Practice

    Författare :Sadaf Salavati; Anita Mirijamdotter; Christina Mörtberg; Jeremy Rose; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cognitive Mapping; compulsory school education; digital technologies; focused ethnography; teachers; Soft Systems Methodology; Systems Thinking; Informatik; Information Systems;

    Sammanfattning : In this dissertation the complex, dynamic, contextual and multi-dimensional practice of teachers’ use of digital technologies in their everyday work has been illustrated and presented. The research draws upon the experience of teachers and school leaders from two compulsory schools as well as representatives from the municipal Department of Education and IT-unit within a municipality in the south of Sweden.
