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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  3. 3. Motivation, students, and the classroom environment : exploring the role of Swedish students’ achievement goals in chemistry

    Author : Anders Hofverberg; Mikael T. Winberg; Ewa Bergqvist; Ilka Parchmann; Corwin Senko; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Motivation; achievement goals; chemistry; goal structures; epistemic beliefs; autonomous motivation; pedagogiskt arbete; educational work; education; pedagogik; kemididaktik; didactics of chemistry;

    Abstract : The overarching aim of this thesis is to deepen the knowledge about students’ achievement goals in chemistry and how they relate to students’ epistemic beliefs (beliefs about knowledge) and to their perceptions of classroom goal structures (instructional practices that emphasize certain achievement goals). Achievement goals are defined as the purpose behind students’ engagement in achievement behavior. READ MORE

  4. 4. Reasoning with thermal cameras : Framing and meaning-making in naturalistic settings in higher education

    Author : Robin Samuelsson; Jesper Haglund; Maja Elmgren; Cedric Linder; Tor Nilsson; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; Physics Education Research; IR cameras; thermal cameras; thermodynamics; phase transition; heat transfer; Resources framework; Social semiotics; teacher education; chemistry education; visualization; Fysikdidaktik; kemididaktik; värmekamera; lärarutbildning; termodynamik; fasövergång; lärandesekvens; Socialsemiotik; Resursramverket; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Abstract : In this Licentiate thesis, framed by the Resources framework and Social semiotics, I explore how students and instructors, investigating thermal phenomena with IR cameras, come to conceptually and epistemologically frame the naturalistic settings they participate in. Additionally, I look at how they productively employ resources , what barriers they encounter while reasoning about the thermal phenomena and how the semiotic resources of the IR camera relate to the framing and resources employed in their investigations.

  5. 5. Sharing lived experience : How upper secondary school chemistry teachers and students use narratives to make chemistry more meaningful

    Author : Agneta Boström; Per Olof Wickman; Russell Tytler; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Chemistry; cognition; Dewey; knowledge emphases; learning; meaning-making; narrative; narrative inquiry; pedagogical content knowledge; post-modernity; pragmatism; science education; teaching; the content of science; Subject didactics; Ämnesdidaktik;

    Abstract : This dissertation concerns the place of teachers’ and students’ narratives in making school chemistry more meaningful to students. The material was collected at upper secondary school courses and consists of interviews with six experienced chemistry teachers, five adult students attending evening classes and six younger students.
