1. Redox models in chemistry : A depiction of the conceptions held by secondary school students of redox reactions
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
2. Models in chemistry education : A study of teaching and learning acids and bases in Swedish upper secondary schools
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
3. Facets of chemical bonding that enhance or encumber conceptual understanding
Sammanfattning : 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.

4. Exploring processes and resources for problem solving at the crossroads between chemistry and mathematics
Sammanfattning : 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. LÄS MER
5. Motivation, students, and the classroom environment : exploring the role of Swedish students’ achievement goals in chemistry
Sammanfattning : 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. LÄS MER
