1. Models of chemical bonding : Representations Used in School Textbooks and by Teachers and their Relation to Students´Difficulties in Understanding
Sammanfattning : This thesis focuses on how school textbooks and teachers present models of chemical bonding in upper secondary schools in Sweden. In science, as well as in science education, models play a central role, but research has shown that they often are difficult for students to understand. LÄS MER
2. 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.

3. Teaching and learning of chemical bonding models : Aspects of textbooks, students’ understanding and teachers’ professional knowledge
Sammanfattning : Despite the growing importance of science and technology in society, school students consider these subjects irrelevant and hard to learn. Teachers must therefore know how to teach science in ways that enhance students’ understanding and interest. LÄS MER
4. Exploring the role that visual representations play when teaching and learning chemical bonding : An approach built on social semiotics and phenomenography
Sammanfattning : In this thesis, I explore the role that visual representations play in the teaching and learning of chemistry, using chemical bonding as a particular case. I do this in a novel way by drawing on a combination of social semiotics and phenomenography. LÄS MER
5. Relationships between models used for teaching chemistry and those expressed by students
Sammanfattning : This thesis is focused upon chemistry as a school subject and students' interpretations and use of formally introduced teaching models. To explore students' developing repertoire of chemical models, a longitudinal interview study was undertaken spanning the first year of upper secondary school chemistry. LÄS MER
