En ungdomsskolelærers oppfatning om bruk av praktiske aktiviteter i matematikkundervisningen
(Master thesis, 2015)The aim of this study was to illuminate a teacher’s beliefs and attitudes towards practical activities in mathematics. To reveal this, I developed a teaching plan consisting of four activities. In which the students were ... -
Energy dissipation and hysteresis cycles in pre-sliding transients of kinetic friction
(Peer reviewed; Journal article, 2023)The problem of transient hysteresis cycles induced by the pre-sliding kinetic friction is relevant for analyzing the system dynamics, e.g., of micro- and nano-positioning instruments and devices and their controlled ... -
Engaging Mathematical Reasoning-and-Proving: A Task, a Method, and a Taxonomy
(Journal article; Peer reviewed, 2019)This article is the second paper in a series of papers on studies focusing on teaching mathematical reasoning-and-proving in elementary mathematics classroom. Participants are in-service teachers enrolled in a continuing ... -
Ergodic theory of simple continued fractions
(Master thesis, 2022)This thesis combines two fields of mathematics: number theory and ergodic theory (as part of dynamical systems). We study a special representation of numbers throughout the thesis: the simple continued fraction. We ... -
Et introduksjonskurs til GeoGebra : en designstudie av introduksjonskurset med fokus på å lære å bruke i 1T i videregående skole
(Master thesis, 2016)As a teacher, I have observed over the past years a change in focus on the use of tools in the teaching of mathematics. Starting in spring 2015 the use of digital tools by students will be a requirement in the examinations ... -
Euclid’s proof of the infinitude of primes: distorted, clarified, made obsolete, and confirmed in modern mathematics
(Journal article; Peer reviewed, 2014) -
EVU-studenters oppfattelse av nytte ved analyse av egne elevers resonnement og argumentasjon – En kvalitativ casestudie
(Master thesis, 2021)This qualitative case study investigated what in-service teachers viewed as useful in evaluating their own students' reasoning and argumentation. This was done in response to the following research question: How do in-service ... -
Exploring Affordances of an Online Environment : A Case-Study of Electronics Engineering Undergraduate Students’ Activity in Mathematics
(Journal article; Peer reviewed, 2019) -
Exploring grade 9 students' assumption making when mathematizing
(Chapter; Peer reviewed, 2015) -
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 ... -
Exploring students’ metacognition in relation to an integral-area evaluation task
(Peer reviewed; Journal article, 2021) -
Exploring Students’ Metacognitive Knowledge: The Case of Integral Calculus
(Peer reviewed; Journal article, 2020) -
Exposing Empirical Links between COVID-19 Situation Report and Available Data: The Case of Nigeria
(Peer reviewed; Journal article, 2020) -
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 ... -
Factorizations and Singular Value Estimates of Operators with Gelfand–Shilov and Pilipović kernels
(Journal article; Peer reviewed, 2017)We prove that any linear operator with kernel in a Pilipović or Gelfand–Shilov space can be factorized by two operators in the same class. We also give links on numerical approximations for such compositions. We apply these ... -
First-year engineering students’ use of their mathematics textbook - opportunities and constraints
(Journal article; Peer reviewed, 2012)The role of the mathematics textbook at tertiary level has received limited exposure in previous research although it is likely that students work individually and that some of this work depends on the use of the textbook. ... -
Forms of epistemic feedback
(Chapter, 2022)Feedback in a digital learning system has two functions, a pragmatic and an epistemic one. In previous papers, we were concerned with the pragmatic function, showing how digital feedback initiates acting with the system ... -
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 ... -
A framework for reasoning in school mathematics: analyzing the development of mathematical claims
(Peer reviewed; Journal article, 2024)This study introduces a framework for analyzing opportunities for mathematical reasoning (MR) in school mathematics, using MR-relevant claims and their derivation as the unit of analysis. We contend that this approach can ... -
Frequency-based ensemble forecasting model for time series forecasting
(Peer reviewed; Journal article, 2022)The M4 forecasting competition challenged the participants to forecast 100,000 time series with different frequencies: hourly, daily, weekly, monthly, quarterly, and yearly. These series come mainly from the economic, ...
