  1. 1. Undervisa Naturvetenskap genom Inquiry : En studie av två högstadielärare

    Författare :Ingrid Lundh; Andreas Redfors; Maria Rosberg; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inquiry-teaching; Inquiry-learning; Nature of science; Nature of scientific inquiry; Professional development;

    Sammanfattning : There is a need to change the teaching methods of the science subjects. International surveys, e.g. TIMMS and PISA, have been showing relatively declining skills for the Swedish students in the science subjects. LÄS MER

  3. 2. Ett frö för lärande : en variationsteoretisk studie av undervisning och lärande i grundskolans biologi

    Författare :Anna Vikström; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Första delen av denna avhandling utgörs av en licentiatuppsats: Från görande till rikare lärande (Vikström, 2002). I uppsatsen beskrivs en aktionsforskningsstudie där lärare i skolår 1-6 utvecklar sin kompetens att undervisa i naturvetenskap. LÄS MER

  4. 3. Sample preparation and analysis of metabolites from plants in the families of Cyperaceae, Poaceae and Apiaceae

    Författare :Linus Svenberg; Åsa Emmer; Jenny Lindh; Margareta Sandahl; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gas chromatography; Mass spectrometry; Ultrasound assisted extraction; Solid-phase microextraction; Volatile compounds; Allelopathy; Bioassay; Gaskromatografi; Masspektrometri; Ultraljudsassisterad extraktion; fastfas-mikroextraktion; Flyktiga ämnen; Allelopati; Bioanalys; Kemi; Chemistry;

    Sammanfattning : An important aspect of understanding how plants effect their environmentis the study of volatile compounds and how these influence interactions between plants and other living organisms. The study of these secondary metabolites from plants can be used in practical applications, such as behaviour control of insects, and is an important part in the search for novel compounds that can be used to influence the behaviour of disease spreading vectors.

  5. 4. Teaching and Learning Concurrent Programming in the Shared Memory Model

    Författare :Filip Strömbäck; Linda Mannila; Mariam Kamkar; Christoph Kessler; Mikko-Jussi Laakso; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Concurrency; Synchronization; Programming; Computer science education; Visualization; Progvis;

    Sammanfattning : The performance of computational devices is steadily increasing. Recently, the main contributor to the increasing performance has been an increasing number of cores rather than increased performance for individual cores. LÄS MER

  7. 5. Learning to Teach and Teaching to Learn : Primary science student teachers´ complex journey from learners to teachers

    Författare :Pernilla Nilsson; Claes Ericsson; Christopher Clark; Linköpings universitet; []
    Nyckelord :Experience; reflection; PCK; primary science; student teacher; teacher education; Erfarenhet; lärarstudent; lärarutbildning; naturvetenskap; PCK; reflektion; ämnesdidaktisk kunskap; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Social sciences;

    Sammanfattning : This thesis concerns the process of student teachers´ learning to teach primary science and is based on four studies involving primary science student teachers during their teacher education program. The overall question that the thesis intends to investigate is in which ways student teachers’ learning about teaching can be illustrated and understood in terms of the critical aspects that are experienced within their teaching and learning practices.
