Onset of Convection in an Inclined Anisotropic Porous Layer with Internal Heat Generation
(Peer reviewed; Journal article, 2019)The onset of convection in an inclined porous layer which is heated internally by a uniform distribution of heat sources is considered. We investigate the combined effects of inclination, anisotropy and internal heat ... -
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 ... -
Perspectives and reflections on teaching linear algebra
(Peer reviewed; Journal article, 2020)This paper presents ‘expert opinions’ on what should be taught in a first-year linear algebra course at university; the aim is to gain a generic picture and general guiding principles for such a course. Drawing on a Delphi ... -
Prospective mathematics teachers? self-referential metaphors as indicators of the emerging professional identity
(Peer reviewed; Journal article, 2019)Ideals play a key role in a student teachers’ identity work. They form targets to strive for and a mirror for reflection. In this paper, we examine Finnish mathematics student teachers’ metaphors for the teacher’s role ... -
Qualities in mathematical discourses in kindergartens
(Peer reviewed; Journal article, 2020)In this study we investigated qualities of the mathematical discourse in four kindergarten classes in which kindergarten teachers and 5-year-old children engaged in mathematical learning activities. We analysed differences ... -
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 ... -
Recent Nordic research in mathematics education illustrated by examples from NORMA17
(Peer reviewed; Journal article, 2021)A characterization of recent Nordic research in didactics of mathematics is presented based on the 32 research reports from the Nordic and Baltic countries in the proceedings from NORMA17 (The eighth Nordic conference on ... -
Researching Mathematics Pedagogy
(Research in Mathematics Education, Chapter; Peer reviewed, 2020) -
Richard von Mises’ work for ZAMM until his emigration in 1933 and glimpses of the later history of ZAMM
(Peer reviewed; Journal article, 2020) -
The Role of Feedback When Learning with a Digital Artifact: A Theory Networking Case on Multimodal Algebra Learning
(Peer reviewed; Journal article, 2023)How digital feedback supports teaching/learning with a digital tool is not yet well understood. In a networking of theories approach, Activity Theory and the Instrumental Approach are combined to investigate the role of ... -
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 ... -
Self-efficacy and approaches to learning mathematics among engineering students : empirical evidence for potential causal relations
(Journal article; Peer reviewed, 2020) -
Self-Efficacy Between Previous and Current Mathematics Performance of Undergraduate Students : An Instrumental Variable Approach to Exposing a Causal Relationship
(Peer reviewed; Journal article, 2021) -
The sine anecdote in Kovalevskaya’s memoirs
(Peer reviewed; Journal article, 2022) -
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 ... -
Some remarks and documents concerning the emigration of Polish mathematicians during the 1930s and early 1940s
(Journal article; Peer reviewed, 2019) -
The spirit of mathematical modelling – a philosophical study on the occasion of 50 years of mathematical modeling education
(Peer reviewed; Journal article, 2023)We mark the 50th anniversary of mathematical modeling education by reviving the term the spirit of mathematical modeling (SoMM), which idealistically reflects core aspects of mathematical modeling. The basis of our analysis ... -
Switching to Fully Online Teaching and Learning of Mathematics: The Case of Norwegian Mathematics Lecturers and University Students During the Covid‑19 Pandemic

Task Contexts in Dutch Mathematics Education
(Chapter; Peer reviewed, 2020)This chapter offers a description of task contexts in mathematics education in the Netherlands. International comparative studies show that the Dutch average percentage of mathematics tasks with real-life connections per ...
