‘I finally understand my mistakes’ – the benefits of screencast feedback
(Peer reviewed; Journal article, 2023)This study explores the impact of screencast feedback on maths tests for junior and high school students. While prior research emphasises the influence of feedback on learning, its effectiveness varies with type and delivery. ... -
Interdisciplinary primary school curriculum units for sustainable development
(Journal article; Peer reviewed, 2020)Education for sustainable development (ESD) provides crucial opportunities for young people to be involved in complex sustainability issues. This study contributes to existing knowledge about primary school teachers’ ... -
Inverse problems for a model of biofilm growth
(Peer reviewed; Journal article, 2023)A bacterial biofilm is an aggregate of micro-organisms growing fixed onto a solid surface, rather than floating freely in a liquid. Biofilms play a major role in various practical situations such as surgical infections and ... -
«Jeg ble langt mer skjerpet» – erfaringer med digitalt samarbeid om undervisningspraksis
(Peer reviewed; Journal article, 2021)I denne artikkelen presenteres en studie som undersøker hvordan et kollegialt samarbeidsprosjekt formes og påvirkes av digital teknologi. Studien er et selvstudium gjort av fire lærerutdannere i barnehagelærerutdanningen ... -
Kritisk matematikkundervisning - en vei til demokratisk dannelse
(Others, 2023)Sørger matematikkundervisningen for at våre fremtidige samfunnsborgere får den matematiske kompetansen de trenger for å kunne forholde seg kritisk til samfunnsutfordringer? Denne artikkelen presenterer Critical Mathematics ... -
Markov Chain Monte Carlo Methods Applied to a Synchronous Generator Model
(Peer reviewed; Journal article, 2023)Markov Chain Monte Carlo (MCMC) approaches are widely used for tuning model parameters to fit process measurements. While modern probabilistic programming languages (PPLs) such as Stan, PyMC, and Turing have made it easier ... -
A mathematics teacher’s storylines about CME-teachings, mathemacy and newly arrived students’ mathematical competence
(Peer reviewed; Journal article, 2023)This article highlights storylines that have emerged during interviews with a teacher who is trying out Critical Mathematics Education in his multicultural and multilingual class of 10th grade students. The aims for the ... -
Merging and comparing three mitochondrial markers for phylogenetic studies of Eurasian reindeer (Rangifer tarandus)
(Journal article; Peer reviewed, 2016)Phylogenetic analyses provide information that can be useful in the conservation of genetic variation by identifying intraspecific genetic structure. Reconstruction of phylogenetic relationships requires the use of markers ... -
"Minoritised mathematics students are motivated by gratitude": An analysis of storylines in Norwegian public media
(Peer reviewed; Journal article, 2021)As part of a larger participatory research project, we examine storylines about mathematics education and students from minoritised cultures and/or languages in Norwegian news media. We identify some of the positionings ... -
Modeling and Analysis of Fluid Flow through A Non-Prismatic Open Channel with Application to Drilling
(Journal article; Peer reviewed, 2018)This paper presents the development and validation of a simplified dynamic model of a Venturi channel. The existing dynamic models on open channels are based on the open channel flow principles, which are the shallow water ... -
Modelling and Simulation of Detection Rates of Emergent Behaviours in System Integration Test Regimes
(Peer reviewed; Journal article, 2021)System level testing generally lacks coverage due to cost of performing realistic tests on the “system as a whole”. This lack in test coverage gives rise to seemingly emergent aviour at system level. The interactions between ... -
Norske jenter og gutter i ungdomsskolen har blitt likere i naturfaginteresse – men mer ulike når det gjelder miljøengasjement. Første resultater fra den norske ROSES-undersøkelsen 2020
(Peer reviewed; Journal article, 2022)I denne artikkelen presenterer vi data fra en spørreundersøkelse i 2019/20 blant norske 10. klassinger om naturfag og teknologi. Undersøkelsen (kalt ROSES) bygger på ROSE-prosjektet, som ble ledet av Svein Sjøberg i første ... -
