  1. 1. 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

  3. 2. On the Metric-based Approach to Supervised Concept Learning

    Författare :Niklas Lavesson; Sweden Karlskrona Blekinge Institute of Technology School of Engineering Department of Systems and Software Engineering; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; classifier evaluation; supervised learning; metric; criteria;

    Sammanfattning : A classifier is a piece of software that is able to categorize objects for which the class is unknown. The task of automatically generating classifiers by generalizing from examples is an important problem in many practical applications. This problem is often referred to as supervised concept learning, and has been shown to be relevant in e.g. LÄS MER

  4. 3. "Vad skulle x kunna vara?" : andragradsekvation och andragradsfunktion som objekt för lärande

    Författare :Constanta Olteanu; Shirley Booth; Torgny Ottosson; Ingemar Holgersson; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP; parameters; unknown quantity; argument; second degree equations; quadratic functions; teaching; mathematics education; experience; theory of variation; dimensions of variation; Education; Pedagogik; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; MATHEMATICS; MATEMATIK;

    Sammanfattning : Algebraic equations and functions play an important role in various mathematical topics, including algebra, trigonometry, linear programming and calculus. Accordingly, various documents, such as the most recent Swedish curriculum (Lpf 94) for upper secondary school and the course syllabi in mathematics, specify what the students should learn in Mathematics Course B.

  5. 4. Exploring student collaboration during Data Generation in the Statistics Classroom : An Inferentialist Perspective

    Författare :Abdel Seidouvy; Maike Schindler; Ola Helenius; Dani Ben-Zvi; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inferentialism; Collaboration; Data generation; Statistics;

    Sammanfattning : This dissertation explores student collaboration during data generation in statistics. The first aim is to put the semantic theory of inferentialism to work and develop a theoretical lens for exploring student collaboration during data generation. LÄS MER

  7. 5. Travelling through time : Students’ interpretation of evolutionary time in dynamic visualizations

    Författare :Jörgen Stenlund; Lena Tibell; Konrad Schönborn; Niklas Gericke; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evolution; visualization; time; learning; threshold; zooming;

    Sammanfattning : Evolutionary knowledge is important to understand and address contemporary challenges such as loss of biodiversity, climate change and antibiotic resistance. An important aspect that is considered to be a threshold concept in teaching and learning about evolution is the time it involves. LÄS MER
