1. Models of chemical bonding : Representations Used in School Textbooks and by Teachers and their Relation to Students´Difficulties in Understanding
Abstract : 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. READ MORE

2. Computational Studies of Chemical Interactions: Molecules, Surfaces and Copper Corrosion
Abstract : The chemical bond – a corner stone in science and a prerequisite for life – is the focus of this thesis. Fundamental and applied aspects of chemical bonding are covered including the development of new computational methods for the characterization and rationalization of chemical interactions. READ MORE

3. Teaching and learning of chemical bonding models : Aspects of textbooks, students’ understanding and teachers’ professional knowledge
Abstract : 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. READ MORE

4. Synthesis, Properties and Bonding in Hume-Rothery Transition-metal Gallides and Indides
Abstract : In this work the intermetallic systems formed by transition-metals from group 5 to 9 with Ga, In and Zn have been experimentally and theoretically studied in detail. Syntheses, compositional analyses, X-ray and neutron diffraction (single crystal as well as powder) and measurements of physical properties, e.g. READ MORE

5. Facets of chemical bonding that enhance or encumber 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.
