  1. 1. Redox models in chemistry : A depiction of the conceptions held by secondary school students of redox reactions

    Författare :Lise-Lotte Österlund; Margareta Ekborg; Anders Berg; Christiane Funk; Astrid Bulte; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; science education; redox reaction; model; inorganic chemistry; organic chemistry; biochemistry; students conceptions; textbook; Other chemistry; Övrig kemi; didactics of chemistry; kemididaktik;

    Sammanfattning : According to previous research, students show difficulties in learning redox reactions. By the historical development different redox models exist to explain redox reactions, the oxygen model, the hydrogen model, the electron model and the oxidation number model. LÄS MER

  3. 2. Models in chemistry education : A study of teaching and learning acids and bases in Swedish upper secondary schools

    Författare :Michal Drechsler; Jan van Driel; Helge Strömdahl; Ingo Eilks; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry Education; Chemistry; Kemi; Chemistry; Kemi;

    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

  4. 3. Green Chemistry in Chemical Education and Synthetic Applications of Sulfinamides
