1. Skolans matematik : En kritisk analys av den svenska skolmatematikens förhistoria, uppkomst och utveckling
Sammanfattning : I argue that common beliefs regarding mathematics originate in the practices of elementary mathematics instruction rather than in science. While learning how to solve mathematical problems in school, we come to believe that mathematics has a set of properties in itself, for instance that it is useful in everyday life, even though this is not necessarily so.

2. Representationer, visualisering och resonemang i geometri : Praktiknära studier i digitala lärmiljöer
Sammanfattning : The aim of this dissertation was to gain a deeper understanding of how teaching in digital environments can be designed to give students opportunities to develop knowledge in two- and three-dimensional geometry. The dissertation consists of two sub-studies, the first using an ethnographic approach in which the researcher followed a teacher's teaching in a digital environment, in a Grade 9 class for a period of five weeks.

3. On Latin squares and avoidable arrays
Sammanfattning : This thesis consists of the four papers listed below and a survey of the research area. I Lina J. Andrén: Avoiding (m, m, m)-arrays of order n = 2k II Lina J. Andrén: Avoidability of random arrays III Lina J. LÄS MER
4. Inget klöver utan matematik : En studie av matematik i yrkesutbildning och yrkesliv
Sammanfattning : Syftet med avhandlingen är att öka förståelsen för aspekter som inverkar på relationen mellan yrkeselevers kunskaper och de kunskaper som behövs i yrkeslivet. Detta görs genom att undersöka olika aktörers perspektiv på yrkeslivets behov av matematikkunskaper, matematikundervisning på yrkesprogram och utformningen av läroplanen Gy11. LÄS MER
5. Optimization, Matroids and Error-Correcting Codes
Sammanfattning : The first subject we investigate in this thesis deals with optimization problems on graphs. The edges are given costs defined by the values of independent exponential random variables. We show how to calculate some or all moments of the distributions of the costs of some optimization problems on graphs. LÄS MER
