Tenth grade pupils engagement with the use of brackets in algebra : a case study in a school in Albania
(Master thesis, 2012)Since algebra is considered as a language, it has its syntax, semantics, and pragmatics. In the third linguistic level (pragmatics) stand the relations between the elements of language and the users. Since brackets are ... -
Professional mathematics teacher identity: analysis of reflective narratives from discourses and activities
(Journal article; Peer reviewed, 2012)This article focuses on the methodological use of reflective narratives from discourses and activities of an experienced primary teacher as evidence of her professional identity. The teacher’s reflective narratives emerge ... -
The introduction of algebra : comparative studies of textbooks in Finland, Norway, Sweden and USA
(Master thesis, 2012)This master thesis is a comparative analysis of textbooks from four different countries, Finland, Norway, Sweden and USA (California), concerning the introduction of algebra. The topic for this research was inspired and ... -
A three-dimensional study of the onset of convection in a horizontal, rectangular porous channel heated from below
(Journal article; Peer reviewed, 2012)The onset of convection is studied in a rectangular channel filled with a fluid saturated porous medium, bounded above and below by impermeable isothermal walls at unequal temperatures and laterally by partially conducting ... -
Mediated action in teachers’ discussions about mathematics tasks
(Journal article; Peer reviewed, 2012)This paper presents analyses of teachers’ discussions within mathematics teaching developmental research projects, taking mediation as the central construct. The relations in the so-called ‘didactic triangle’ form the basic ... -
Mapping properties for the Bargmann transform on modulation spaces
(Journal article; Peer reviewed, 2012)We investigate mapping properties for the Bargmann transform and prove that this transform is isometric and bijective from modulation spaces to convenient Banach spaces of analytic functions. We also present some consequences. ... -
Onset of convection in a porous rectangular channel with external heat transfer to upper and lower fluid environments
(Journal article; Peer reviewed, 2012)The conditions for the onset of convection in a horizontal rectangular channel filled with a fluid saturated porous medium are studied. The vertical sidewalls are assumed to be impermeable and adiabatic. The horizontal ... -
Elever på yrkesfag og matematikk : en studie av elever på Bygg og Anlegg sine oppfatninger av matematikkfagets relevans for eget yrke
(Master thesis, 2012)In this thesis I want to study what kind of perceptions students within the study programme ”Bygg og Anlegg” have as regards the theme mathematics and its relevance for their profession. I also want to study the mathematics ... -
Utvikling av inquirybasert matematikkundervisning : en kasusstudie av læreres tolkning og bruk av en inquiryinspirert læringsfilosofi formidlet gjennom longitudinelt utviklingsprosjekt
(Master thesis, 2012)The development project LBM – Learning Better Mathematics – took place in schools and kindergartens in Vest-Agder from 2007 to 2010. Two years after its end, I investigate the practice and the beliefs about learning and ... -
A critical view on temperature modelling for application in weather derivatives markets

Dynamics of a single species in a fluctuating environment under periodic yield harvesting
(Journal article; Peer reviewed, 2013)We discuss the effect of a periodic yield harvesting on a single species population whose dynamics in a fluctuating environment is described by the logistic differential equation with periodic coefficients. This problem ... -
Für die Ehre des menschlichen Geistes – Ein neuer Blick auf eine bekannte Kontroverse zwischen Fourier und Jacobi über die Rolle der Anwendungen der Mathematik
(Journal article; Peer reviewed, 2013) -
En matematikklærers bruk av medierende redskaper i undervisning av lengde, areal og volum
(Master thesis, 2013)Denne studien har tittelen «En matematikklærers bruk av medierende redskaper i undervisning av lengde, areal og volum». Målet med denne studien er å studere hvordan en ungdomsskolelærer formidler matematikk til elever ... -
Forskningsbasert lærerutdanning i matematikk : hva betyr forskningsbasert undervisning for GLU studentene i MA-149?
(Master thesis, 2013)It is enshrined in law and regulation that all higher education should be research-based and research-oriented. How a research-based approach should be reflected in the education is not defined clearly, so there is room ... -
Introduksjon av algebra i den norske skole : en sammenligningsstudie av læreres introduksjon og forståelse av algebra på ungdomstrinnet og i den videregående skolen
(Master thesis, 2013)The theme for this study is introduction of algebra. I have focused on how teachers deals with the relationship between a syntactic and a semantic focus, the relationship between procedural and conceptual knowledge, the ... -
Oscillation results for second-order nonlinear neutral differential equations
(Journal article; Peer reviewed, 2013)We obtain several oscillation criteria for a class of second-order nonlinear neutral differential equations. New theorems extend a number of related results reported in the literature and can be used in cases where known ... -
Convective instability in a horizontal porous channel with permeable and conducting side boundaries
(Journal article; Peer reviewed, 2013)The stability analysis of the motionless state of a horizontal porous channel with rectangular cross-section and saturated by a fluid is developed. The heating from below is modelled by a uniform flux, while the top wall ... -
Matematikk i krisetid : matematikk og matematikere etter første verdenskrig, i mellomkrigstiden og under andre verdenskrig i Nederland
(Master thesis, 2013)We have provided new and partly unknown historical material on an important period of social, political and scientific development and change both in the Netherlands and internationally. We focused on the so far neglected ... -
Omvendt undervisning i matematikk : en studie av elevers oppfatning av undervisningsmetoden
(Master thesis, 2013)Many teachers want to try out different teaching methods to find the one that makes students learn best. In today's society we surround ourselves with technology most of the day and there are several teaching methods that ... -
