1. Från naturliga tal till hela tal (från N till Z) : Vad kan göra skillnad för elevers möjligheter att bli bekanta med de negativa talen?
Sammanfattning : The aim of the thesis is to gain knowledge concerning what pupils aged 8 and 9 need to learn to become familiar with negative numbers. The framework used in this research, variation theory, impliesthat students' problems in learning what was intended may have to do with the fact that some critical aspects of the studied object have not yet been discerned by the student.

2. Topology off the beaten path : From critical to non-Hermitian systems
Sammanfattning : A central topic in condensed matter research during the last decades has been the study and classification of topological phases of matter. Topological insulators in particular, a subset of symmetry protected topological phases, have been investigated for over a decade. LÄS MER
3. Kritiska aspekter för att urskilja en del-helhetsstruktur : Ett undervisningsutvecklande forskningsprojekt i grundskolan
Sammanfattning : Syftet med licentiatuppsatsen är att bidra med kunskap om vilka aspekter som kan vara nödvändiga för elever att urskilja för att identifiera och analysera en del-helhetsstruktur och i förlängningen bemästra ekvationer. I forskningsprojektet medverkade lärare och forskare i ett kollaborativt och intervenerande arbete. LÄS MER
4. What is taught and what is learned. Professional insights gained and shared by teachers of mathematics
Sammanfattning : The aim of the thesis is to contribute to knowledge about relationships between teaching and learning in school. The framework used in this research, variation theory, states that, to improve student learning, attention must be paid to what is being learned, the capability that is to be improved and the features (critical features) that it is necessary for the learner to discern.

5. The influence of numbers when students solve equations
Sammanfattning : Is it possible that some students’ primary difficulty with equation-solving is neither handling the literal symbols nor the equality, but the numbers used as coefficients? It is well known that many students find algebra a difficult topic, and there is much research on how students experience this strand of mathematics, with indications of how it can be taught. Still, a perspective not often fronted in this research – that has been suggested as an area potentially important – is how numbers, other than natural numbers, in algebra, are perceived by students.
