2. 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 : 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

4. 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 : 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

5. 3. Facets of chemical bonding that enhance or encumber conceptual understanding

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

   Abstract : 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.

6. 4. Exploring processes and resources for problem solving at the crossroads between chemistry and mathematics

   Author : Sofie Ye; Felix M. Ho; Maja Elmgren; Jonas Bergman Ärlebäck; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; problem solving; mathematical modelling; chemical kinetics; chemistry education research; tertiary education; resources framework; mathematics education research; metacognition; intuition; Kemi; Chemistry; Curriculum Studies; Didaktik; Mathematics; Matematik;

   Abstract : Problem solving at the crossroads between chemistry and mathematics presents significant challenges for students at all levels of education. This licentiate thesis aims to enhance our understanding of such problem solving, with a focus on how university students approach problems in the context of chemical kinetics. READ MORE

7. 5. 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 : 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
