    Sammanfattning : This thesis reports an investigation of how acid-base models are taught and understood in Swedish upper secondary school. The definition of the concepts of acids and bases has evolved from a phenomenological level to an abstract (particle) level. Several models of acids and bases are introduced in Swedish secondary school. LÄS MER

  5. 4. Models of chemical bonding : Representations Used in School Textbooks and by Teachers and their Relation to Students´Difficulties in Understanding

    Författare :Anna Bergqvist; Michal Drechsler; Shu-Nu Chang Rundgren; Pernilla Nilsson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pedagogical content knowledge; chemical bonding; textbook analysis; students learning difficulties; models in science education; Kemi; Chemistry;

    Sammanfattning : This thesis focuses on how school textbooks and teachers present models of chemical bonding in upper secondary schools in Sweden. In science, as well as in science education, models play a central role, but research has shown that they often are difficult for students to understand. LÄS MER

  7. 5. När läroplan och tradition möts : Om lärarfortbildning och undersökande aktiviteters syfte inom den laborativa NO-undervisningen i grundskolans senare del

    Författare :Torodd Lunde; Shu-Nu Chang Rundgren; Michal Drechsler; Erik Knain; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; inquiry-based science teaching; laboratory work; teaching tradition; lower secondary; teacher professional development; undersökande arbetssätt; lärarfortbildning; undervisning; natururorienterande ämnen; laborationer; grundskolans senare del; läroplan; undervisningstradition; Kemi; Chemistry;

    Sammanfattning : The Swedish curricula for compulsory school science emphasize laboratory inquiry-based science teaching (IBST) to develop pupils’ critical thinking. In contrast, several studies indicate that teachers within the Swedish teaching tradition almost solely emphasize laboratory work as a way to gain students understanding of traditional science content.
