Learning to teach a mathematical emotional orientation
(For the Learning of Mathematics; no. 40, Chapter; Peer reviewed, 2020) 
Linear instability of mixed convection of cold water in a porous layer induced by viscous dissipation
(Journal article; Peer reviewed, 2009)An analysis of linear stability of the stationary laminar Darcy flow in a horizontal porous layer is performed. The porous layer is saturated with cold water. The upper plane boundary is assumed to be subject to heat ... 
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. ... 
Mathematical learning opportunities in kindergarten through the use of digital tools: Affordances and constraints
(Journal article; Peer reviewed, 2013)This study aims at scrutinising the mathematical learning opportunities of children engaging with digital tools and the emerging affordances and constraints faced in such settings. By adopting a sociocultural perspective ... 
Mathematics teaching development: Learning from developmental research in Norway
(Journal article; Peer reviewed, 2014)This paper is a product of mathematics teaching developmental research projects based on establishing communities of inquiry comprising schoolteachers working at all grades and universitybased teacher educator/researchers ... 
Mathematics Video Podcasts as Integrated Elements of Online Lessons in Further University Education: InService Teachers’ Flow Experiences
(Journal article; Peer reviewed, 2017)This casestudy examined inservice teachers’ perceptions of learning by means of online mathematic lessons consisting of a mix of text and video podcasts. The investigation is part of further university education directed ... 
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 socalled ‘didactic triangle’ form the basic ... 
A NonnormalMode Marginal State of Convection in a Porous Rectangle
(Journal article; Peer reviewed, 2019)The fourthorder Darcy–Bénard eigenvalue problem for onset of thermal convection in a 2D rectangular porous box is investigated. The conventional type of solution has normalmode dependency in at least one of the two spatial ... 
Nonstandard Problems in an Ordinary Differential Equations Course
(Journal article; Peer reviewed, 2018) 
On Science Museums, Science Capital, and the Public Understanding of Mathematical Modelling
(International Perspectives on the Teaching and Learning of Mathematical Modelling; no. 6, Chapter; Peer reviewed, 2020) 
On stability of linear dynamic systems with hysteresis feedback
(Journal article; Peer reviewed, 2020)The stability of linear dynamic systems with hysteresis in feedback is considered. While the absolute stability for memoryless nonlinearities (known as Lure’s problem) can be proved by the wellknown circle criterion, the ...

(Journal article; Peer reviewed, 2020)Abstract. The stability of linear dynamic systems with hysteresis in feedback is considered. While the absolute stability for memoryless nonlinearities (known as Lure’s problem) can be proved by the wellknown circle ... 
On the asymptotic behavior of solutions to a class of thirdorder nonlinear neutral differential equations
(Peer reviewed; Journal article, 2020)By using comparison principles, we analyze the asymptotic behavior of solutions to a class of thirdorder nonlinear neutral differential equations. Due to less restrictive assumptions on the coefficients of the equation ...

On the thermal instability in a horizontal rectangular porous channel heated from below by a constant flux
(Journal article; Peer reviewed, 2014)The onset of thermoconvective instability in a rectangular horizontal channel filled with a fluidsaturated porous medium is studied. The channel is heated from below with a constant flux. The top wall is maintained at a ... 
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 ... 
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 ...
