11. Canonical Bases for Algebraic Computations
Sammanfattning : This thesis deals with computational methods in algebra, mainly focusing on the concept of Gröbner and SAGBI bases in non-commutative algebras. The material has a natural division into two parts. The first part is a rather extensive treatment of the basic theory of Gröbner bases and SAGBI bases in the non-commutative polynomial ring. LÄS MER
12. Approaching Proof in a Community of Mathematical Practice
Sammanfattning : This thesis aims to describe how students encounter proof in a community of mathematical practice at a mathematics department and how they are drawn to share mathematicians’ views and knowledge of proof. Considering the department as a community of practice where the joint enterprise is learning mathematics in a broad sense made it possible to perceive the newcomers as active participants in the practice.

13. Exploring Probabilistic Reasoning : A Study of How Students Contextualise Compound Chance Encounters in Explorative Settings
Sammanfattning : This thesis aims at exploring how probabilistic reasoning arises in explorative learning situations that are random in nature. The focus is especially on what learners with scant experience of formal theories of probability do and can do when dealing with compound random situations in which they are offered opportunities to integrate different probabilistic lines of reasoning.

14. Matematik och bildning : berättelse, gräns, tystnad : Mathematics and Liberal Education: narrative, limit, tacitness
Sammanfattning : Mathemathics and Liberal Education – narrative, limit, tacitness is a study of mathematics as a special human endeavour to grasp and understand the world. Mathematics is seen as a cultural activity related to other cultural phenomena as music, art and literature, but also as a very efficient modelling tool for science, economy and social organisation.

15. Lärares och elevers användande av laborativt material i bråkundervisningen i skolår 4-6 : Vad görs möjligt för eleverna att erfara?
Sammanfattning : Syftet med studien är att beskriva och analysera lärares och elevers användande av laborativt material i skolår 4-6 när de arbetar med tal i bråkform i matematikundervisningen. Centrala frågor i studien handlar om på vilka sätt det laborativa materialet används i bråkundervisningen, vilka typer av laborativt material används i bråkkundervisningen, vilka dimensioner av variation öppnas upp om tal i bråkform när laborativt material används samt vad som görs möjligt för eleverna att erfara om tal i bråkform.
