Random dynamical system generated by the 3D Navier-Stokes equation with rough transport noise
(Peer reviewed; Journal article, 2022)We consider the Navier-Stokes system in three dimensions perturbed by a transport noise which is sufficiently smooth in space and rough in time. The existence of a weak solution was proved in [26], however, as in the ... -
Solution properties of the incompressible Euler system with rough path advection
(Peer reviewed; Journal article, 2022)The present paper aims to establish the local well-posedness of Euler's fluid equations on geometric rough paths. In particular, we consider the Euler equations for the incompressible flow of an ideal fluid whose Lagrangian ... -
A Collaboratively-Derived Research Agenda for E-assessment in Undergraduate Mathematics
(Peer reviewed; Journal article, 2022)This paper describes the collaborative development of an agenda for research on e-assessment in undergraduate mathematics. We built on an established approach to develop the agenda from the contributions of 22 mathematics ... -
The Limit Notion at Three Educational Levels in Three Countries
(Peer reviewed; Journal article, 2022)This paper documents how the limit concept is treated in high school, at a university and in teacher education in England, France and Sweden. To this end we make use of vignettes, data-grounded accounts of the situation ... -
Variational principles for fluid dynamics on rough paths
(Peer reviewed; Journal article, 2022) -
Asymptotic geometry and Delta-points
(Peer reviewed; Journal article, 2022)We study Daugavet- and Δ-points in Banach spaces. A norm one element x is a Daugavet-point (respectively, a Δ-point) if in every slice of the unit ball (respectively, in every slice of the unit ball containing x) you can ... -
Grade 8 students appropriating Sankey diagrams: The first cycle in an educational design research

Third grade students’ multimodal mathematical reasoning when collaboratively solving combinatorial problems in small groups
(Peer reviewed; Journal article, 2022)The aim of this study is to investigate Norwegian primary school students’ multimodal mathematical reasoning when solving combinatorial problems. The data collection took place in four small groups of altogether thirteen ... -

A transition to online teaching and learning of mathematics in Norwegian higher education institutions: the perspectives of lecturers and students
(Peer reviewed; Journal article, 2022)This paper reports a study of university lecturers’ and students’ experiences of teaching and learning mathematics following the abrupt requirement to switch to online teaching in 2020. A goal of the study is to share ... -
Geometric rough paths on infinite dimensional spaces
(Peer reviewed; Journal article, 2022)Similar to ordinary differential equations, rough paths and rough differential equations can be formulated in a Banach space setting. For α ∈ (1/3,1/2), we give criteria for when we can approximate Banach space-valued ... -
Advancing engineering students’ conceptual understanding through puzzle-based learning: a case study with exact differential equations
(Peer reviewed; Journal article, 2022)Current views on the teaching of differential equations (DEs) are shifting towards the use of graphical and numerical methods. Motivated by recent research suggesting that puzzle-based learning (PzBL) can improve the ... -
Improving students’ mathematics self-efficacy: A systematic review of intervention studies

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, ... -
Programmering i matematikkfaget
(Master thesis, 2022)Tema for denne masteroppgaven er programmering i matematikkfaget. Programmeringen har fått betydelig plass i faget etter at Fagfornyelsen trådte i kraft som ny læreplan høsten 2020. Dette medfører faglige og didaktiske ... -
Hvordan kan lærere skape motivasjon i matematikk gjennom formativ vurdering?
(Master thesis, 2022)I denne masteroppgaven forskes det på hvordan lærere kan skape motivasjon i matematikk gjennom formativ vurdering. Dette gjøres gjennom en aksjonsforskning med tre faser, og for å undersøke elevenes motivasjon i formative ... -
Implementering av programmering i matematikkfaget
(Master thesis, 2022)Ved innføring av ny læreplan LK20 er programmering kommet inn som en del av kompetansemålene i matematikk på i alle trinn i ungdomsskolen. Det er derfor interessant å undersøke i hvilken grad og hvordan matematikklærere ...
