  1. 1. Supporting Learning and Teaching of Chemistry in the Undergraduate Classroom

    Författare :Ilana A. Manneh; Karim Hamza; Carl-Johan Rundgren; Lars Eriksson; Ingo Eilks; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; undergraduate chemistry education; learning and teaching processes; didactic triangle; chemical bonding; tutor-student interaction; practical epistemology analysis; continuity; progression; purposes; naturvetenskapsämnenas didaktik; Science Education;

    Sammanfattning : There is agreement in research about the need to find better ways of teaching chemistry to enhance students’ understanding. This thesis aims to contribute to the understanding of how we better support teaching and learning of undergraduate chemistry to make it meaningful and intelligible for students from the outset.

  3. 2. Coteaching chemical bonding with Upper secondary senior students : A way to refine teachers PCK

    Författare :Felix Schultze; Pernilla Nilsson; Zimmerman Nilsson Marie-Helene; Anna Vikström; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Coteaching; pedagogical content knowledge; pck; chemical bonding; representations; chemistry education; chemistry didactic;

    Sammanfattning : The aim of this study was to investigate how an experienced chemistry teacher gains and refines her pedagogical content knowledge (PCK) by cooperating with two grade 12 students (age 18) as coteachers while teaching chemical bonding in a grade 10 Upper secondary class. The study has been conducted from a sociocultural perspective, especially Vygotsky’s zone of proximal development (ZPD) (Vygotsky, 1978). LÄS MER

  4. 3. Undersökande arbete i en laborativ tradition : Från implicita till explicita syften med praktiskt arbete i grundskolans senare del

    Författare :Torodd Lunde; Niklas Gericke; Michal Drechsler; Per-Olof Wickman; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; science education reseach; didactic models; inquiry-based teaching; selective traditions; teacher professional development; critical realism; Kemi; Chemistry;

    Sammanfattning : The overall purpose of this study is to contribute with increased knowledge of what happens when ideas from science education research are introduced in a teaching tradition where other purposes and ideas have dominated for a long time and how gaps between these can be bridged. The study consists of three sub-studies. LÄS MER

  5. 4. Development of Methods for Phase System Characterization in Liquid Chromatography

    Författare :Jörgen Samuelsson; Torgny Fornstedt; Karin Caldwell; Attila Felinger; Uppsala universitet; []
    Nyckelord :Analytical chemistry; Liquid chromatography; Adsorption isotherms; Adsorption energy distribution; Tracer pulse method; Elution by characteristic points; Peak deformation; Validation; Hybrid column material; Alkaline separation; Injection-profiles; Analytisk kemi;

    Sammanfattning : The aim of this thesis is first and foremost to improve the fundamental knowledge of nonlinear and preparative separation theory by focusing on some of the remaining “white spots” on the theoretical chromatographic map. Secondly, the acquired knowledge is used to develop, validate and execute new methods for phase characterization in liquid chromatography. LÄS MER

  7. 5. Science versus School-science : Multiple models in genetics - The depiction of gene function in upper secondary textbooks and its influence on students' understanding

    Författare :Niklas Gericke; Mariana Hagberg; Doris Jorde; Michael Reiss; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; conceptual change; genetics; history of science; models; nature of science; students’ understanding; textbooks; upper secondary school; Subject didactics; Ämnesdidaktik; Biology; Biologi;

    Sammanfattning : In this thesis I describe a study of how the science of genetics is transformed into school science in upper secondary level textbooks and the impact that this transformation has on students’ understanding. The didactic challenge that we face is to decide which science from the academic disciplines we should bring into schools. LÄS MER
