Involvering i gruppearbeid
(Master thesis, 2023)Forskningsarbeidets formål er å undersøke hvordan elever arbeider i grupper med utforsking- og problemløsningsoppgaver. Gruppearbeid som undervisningsform stiller flere sosiale krav til deltakerne, som for eksempel å kunne ... -
Programmering og algoritmisk tenkning i matematikklærebøker for 8.-10. trinn
(Master thesis, 2023)Programmering og algoritmisk tenkning ble innført i matematikk med de nye læreplanene i 2020. Hvordan dette implementeres i de nye lærebøkene er derfor en aktuell problemstilling. Denne studien undersøker hvordan programmering ... -
Konstruksjon av alternativ stokastisk gradientalgoritmen ved bruk av stokastisk analyse og optimal kontrollteori.
(Master thesis, 2023)Oppgaven viser at den stokastiske gradientalgoritmen med en minibatch størrelse r: x_(k+1) = x_k − η/r sum_(i=1)^n ∇f_i(x_k)1_δ(k+1)(i) konvergerer i fordeling, når læringsraten η → 0 mot løsningen av den stokastiske dif ... -
Variasjon i strømpriser
(Master thesis, 2023)Formålet med denne masteroppgaven er å beskrive strømprisene som en stokastisk differensiallikning med mål om å utvikle modeller som skal representere disse prisene. Disse modellene vil gi oss innsikt i strømprisenes ... -
GPS-based math trails: a multiple case study on benefits and challenges.
(Master thesis, 2023)It is an undeniable fact that mathematics contributes tremendously to human activities. However, some students think of mathematics as boring and unrelated to the environment. Some students have expressed how mathematics ... -
En lærebokanalyse av hvordan de nye lærebøkene i matematikk R1, fra de tre store lærebokforlagene Cappelen Damm, Gyldendal og Aschehoug, legger til rette for at elevene skal kunne nå et utvalg av kompetansemålene som omhandler grenseverdi og derivasjon
(Master thesis, 2023)I denne masteroppgaven har jeg gjort en innholdsanalyse av de nye lærebøkene i matematikk R1 som ble gitt ut i år 2021 i forbindelse med den nye læreplanen, Kunnskapsløftet 2020. Forskningsspørsmålet for denne oppgaven er: ... -
En smågruppes arbeid med problemløsning i videregående skole. En studie av gruppas bruk av strategier og appropriering av ulike medierende verktøy i problemløsningsfasen.
(Master thesis, 2023)Dette er en kvalitativ case-studie som tar for seg en liten gruppe med elever fra andre året i videregående skole som jobber med problemløsning i matematikk. Studien belyser hvilke strategier og medierende verktøy disse ... -
Rough linear PDEs with discontinuous coefficients – existence of solutions via regularization by fractional Brownian motion
(Peer reviewed; Journal article, 2020)We consider two related linear PDE’s perturbed by a fractional Brownian motion. We allow the drift to be discontinuous, in which case the corresponding deterministic equation is ill-posed. However, the noise will be shown ... -
Exploring Realistic Mathematics Education in a Flipped Classroom Context at the Tertiary Level
(Peer reviewed; Journal article, 2020)Flipped classroom (FC) pedagogical frameworks have recently gained considerable popularity, especially at secondary school levels. However, there are rich opportunities to explore FC at tertiary levels, but progress on the ... -
Analysis of relations between attitude towards mathematics, prior knowledge, self-efficacy, expected and actual grades in mathematics
(Chapter, 2022)The purpose of this study is to analyse relations between students’ attitude towards mathematics, prior knowledge, self-efficacy, expected grades, and performance in mathematics among 115 firstyear engineering students. ... -
The sine anecdote in Kovalevskaya’s memoirs
(Peer reviewed; Journal article, 2022)In Sofya Vasilyevna Kovalevskaya’s memoirs there is a rather ambiguous story about how she came to understand trigonometric functions on her own as a teenager by reading the chapter on optics in Tyrtov’s elementary physics ... -
How are proof and proving conceptualized in mathematics curriculum documents in the USA and Japan?
(Chapter; Peer reviewed, 2022)Only a few international comparative studies have reported on proof and proving in curriculum documents. This report proposes a method of comparing the meaning of proof-related words in two specific countries’ curriculum ... -

In-Service Teachers’ Perception of the Usefulness of Analyzing their Lower Secondary Students’ Written Argumentation
(Peer reviewed; Journal article, 2022)This study investigates how in-service teachers perceive analyzing their own lower secondary students’ written argumentation as useful. The participants were lower secondary school teachers enrolled in a university mathematics ... -
An Extension of Weyl’s Equidistribution Theorem to Generalized Polynomials and Applications
(Peer reviewed; Journal article, 2020)Generalized polynomials are mappings obtained from the conventional polynomials by the use of the operations of addition and multiplication and taking the integer part. Extending the classical theorem of Weyl on equidistribution ... -

Isometric factorization of vector measures and applications to spaces of integrable functions
(Peer reviewed; Journal article, 2021)Let X be a Banach space, Σ be a σ-algebra, and be a (countably additive) vector measure. It is a well known consequence of the Davis-Figiel-Johnson-Pełczyński factorization procedure that there exist a reflexive Banach ... -
Grunnskolelærerstudenters erfaring med eBok-basert undervisning i matematikk
(Peer reviewed; Journal article, 2022)I denne artikkelen analyserer vi grunnskolelærerstudenters respons på en eBok-basert undervisningsform i matematikk. Denne eBoka besto av oppgaver med både skriftlige og videobaserte løsningsforslag. Oppgavene ble hentet ... -
Abstraction and embodiment: exploring the process of grasping a general
