  1. 6. Att möjliggöra tekniklärande i konstruktionsaktiviteter : En aktionsforskningsstudie i förskolan

    Författare :Johan Boström; Magnus Hultén; Per Gyberg; Nina Kilbrink; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Preschool; Action research; Technology education; Didactics; Förskolan; Aktionsforskning; Teknikundervisning; Didaktik;

    Sammanfattning : This dissertation examines how technology learning is made possible through teacher-led construction activities in preschool. The dissertation also examines how the preschool teachers’ role and the design of the construction activities were affected by different historical and societal structures as well as the collaboration between research and practice.

  3. 7. Teknik i förskolan – att motverka traditionella könsroller : En aktionsforskningsstudie

    Författare :Johan Boström; Magnus Hultén; Per Gyberg; Eva Björkholm; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This study shows that developing a gender sensitive technology education in apreschool setting is a very complex and multifaceted task. The preschool, andthe preschool teachers, are expected to help the children develop their technologicalawareness and interest in technology without being limited by traditionalperspectives on gender.

  4. 8. Encountering Evolution : Children's Meaning-Making Processes in Collaborative Interactions

    Författare :Johanna Frejd; Magnus Hultén; Karin Stolpe; Konrad Schönborn; Christina Siry; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Meaning-making processes; Science Education; Evolution; Multimodality; Collaborative Interaction; Exploratory studies; Meningsskapandeprocesser; Naturvetenskapsundervisning; Evolution; Multimodalitet; Interaktion; Explorativa studier;

    Sammanfattning : This thesis explores preschool class children’s meaning making processes when they encounter evolution. By adopting social semiotic and sociocultural perspectives on meaning making, three group-based tasks were designed. Video data from the activities were analysed using a multimodal approach. LÄS MER

  5. 9. Fenton Pre-treatment of a Birch Kraft Pulp for MFC preparation

    Författare :Pia Hellström; Helena Håkansson; Anette Heijnesson Hultén; Magnus Paulsson; Monica Ek; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microfibrillated cellulose; Fenton chemistry; carbonyl groups; surface charge; total charge; Enzymatic hydrolysis; Tensile strength; z-directional strength; Chemical Engineering; Kemiteknik;

    Sammanfattning : The potential to use acidic hydrogen peroxide in the presence of ferrous ions (Fenton’s reagent) as a pre-treatment when producing microfibrillar cellulose (MFC) from a fully bleached birch (Betula verucosa) kraft pulp was investigated and the properties of the produced MFC was compared to the properties of a MFC produced with enzymatic pre-treatment with a monocomponent endoglucanase (FiberCare® R). The mechanical treatment to MFC was performed in a laboratory colloid mill or in a pilot high-pressure homogeniser and the pre-treated pulps as well as the produced MFCs were chemically and morphologically characterised.

  7. 10. Making Possible by Making Visible : Learning through Visual Representations in Social Science

    Författare :Ann-Sofie Jägerskog; Cecilia Lundholm; Peter Davies; Magnus Hultén; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social science teaching; visual representation; pricing; causal relationships; teaching and learning; phenomenography; variation theory; practice theory; teaching-learning practice; epistemic practices; upper secondary school; design research; graphs; economics; social studies; ämnesdidaktik med inriktning mot de samhällsvetenskapliga ämnenas didaktik; Teaching and Learning with Specialisation in the Social Sciences Education;

    Sammanfattning : This thesis focuses upon the relationship between teaching and learning of dynamic phenomena and processes in social science and the use of visual representations in social science teaching. Teaching in social science uses many visual representations, such as models, flowcharts and diagrams, in order to help students to grasp phenomena, structures and processes in society. LÄS MER
