  1. 1. Facets of chemical bonding that enhance or encumber conceptual understanding

    Författare :Anders Nimmermark; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; student surveys; chemical bonding; secondary school; tertiary education; coordination chemistry; conceptual understanding;

    Sammanfattning : Chemical bonding is a vast subject, rich in abstract concepts and advanced and less-advanced explanatory models that the learner has to master. In this context, the teaching of chemical bonding at the secondary school level is extremely important, as it has the potential to increase or hinder students’ further understanding of bonding.

  3. 2. Methodology for evaluation of hazards from solid waste and landfill-generated leachate

    Författare :Britt-Marie Svensson; Lennart Mathiasson; Lennart Mårtensson; Ann-Sofi Rehnstam-Holm; Kenneth M. Persson; Högskolan Kristianstad; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Analytical protocol; organic pollutants; toxicity test; landfill leachate; leachate treatment; leaching test; waste acceptance criteria; Chemistry; Kemi; NATURAL SCIENCES; NATURVETENSKAP; leaching test; waste acceptance criteria.;

    Sammanfattning : A methodology based on an analytical protocol for evaluation of hazards from landfill leachate and solid waste is described. A dynamic analytical protocol, the LAQUA protocol, including measurements of inorganic and water-quality parameters, polar and non-polar organic marker compounds, and toxicity, was constructed.

  4. 3. Skolämnet Hem- och konsumentkunskap på 2000-talet : förutsättningar för elevers möjlighet till måluppfyllelse

    Författare :Cecilia Lindblom; Agneta Hörnell; Inger Erixon Arreman; Päivi Palojoki; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Lärande; ramfaktorer; grundskola; hem- och konsumentkunskap; Kostvetenskap; Food and Nutrition;

    Sammanfattning : Background People are faced with a variety of consumer choices every day. If they do not have adequate and appropriate knowledge their choices create a greater risk of negative effects for the environment and the economy, and also for the individual's personal health and economic circumstances.

  5. 4. Science Enacted in Everyday Life: Studies of On-line and Classroom Practice

    Författare :Miranda Rocksén; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; science education; science literacy; public engagement with science; science language; genre; learning; on-line communication; classroom research;

    Sammanfattning : This thesis contributes to the field of science education with two studies investigating science literacy in its practice in everyday life. The approach embrace a view on science learning as embedded in the context of situation, resulting in the study of two practices: on-line communication and science classroom. LÄS MER

  7. 5. Sensemaking in chemistry at upper secondary school

    Författare :Ylva Hamnell -Pamment; Utbildningsvetenskap; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Lärande i kemi; Begripliggörande; Språk; Begreppsutveckling; Lärar-elevinteraktion; Begreppskartor; Samtalsanalys; Chemistry teaching and learning; Sensemaking; Language use; Concept development; Teacher–student interaction; Concept mapping; Conversation analysis;

    Sammanfattning : In chemistry education, student learning difficulties involve connecting theory and phenomena to make sense of chemistry, as well as utilising and understanding the language of chemistry. In this thesis, I examine the relationships among student language use, previous achievement level, and sensemaking in chemistry, as well as how experienced teachers help students make sense of chemistry as part of dialogic interaction during practical work.
