I dette kapitlet belyses vilkår, utfordringer og muligheter for samspill mellom teori og praksis i matematikkdidaktikk, der målet er å utvikle matematikkundervisningen i skolen. Dette gjøres ut fra analyser og erfaringer fra et større forsknings- og utviklingsprosjekt, SUM – Sammenheng gjennom Undersøkende Matematikkundervisning. Prosjektet omhandlet implementering av utforskende matematikkundervisning ...

Det kan gis forskjellige læringsteoretiske begrunnelser for utforskende undervisning, som illustrert i kapittel 1. Men læreres forståelse for og bruk av utforskende undervisning i klasserommet kan ikke utledes utelukkende fra et læringsteoretisk grunnlag. Hvis utforskende undervisning skal fungere i klasserommet, så må undervisningspraksisen utvikles og tilpasses i tett samarbeid med lærere (Blomhøj, ...

Det er mange menneskelige aktiviteter i Nord-Norge som kan påvirke tilstanden for miljø og natur i landsdelen, i tillegg til både klimaendringer og menneskelige aktiviteter utenfor landsdelen. For å beskytte og forbedre miljøet bør den samlede påvirkningen vurderes når ulike myndigheter skal treffe sine beslutninger, inkludert i ulike typer sektorforvaltning. Denne rapporten presenterer 1) en ...

Uncontrolled over-fishing has been exemplified by the UN as a serious ecological challenge and a major threat to sustainable food supplies. Emerging trends within governing bodies point towards digital solutions by deploying CCTV-based video monitoring systems on a large scale. We conjecture that such systems are not feasible when reliant on satellite broadband in remote areas, and expose workers ...

In the context of Edge Computing or Cyber-Physical Systems, cross-functional, and cross-geographical DevOps teams are in charge of automating deployments, configuration, and management (i.e., reconfiguration) of complex, large-scale, highly dynamic, and geo-distributed service-oriented software systems. In this context, DevOps teams cannot reasonably manually coordinate their reconfiguration operations ...

Unmanned aerial vehicles (UAVs) are regarded as a potential platform for deploying airborne free space optical (FSO) fronthaul/backhaul links. The challenge emerges from the UAV hovering mobility which deteriorates beam alignment. To solve this challenge, we conducted two hover flights using a quadrotor UAV to measure vibration levels and hover fluctuations offering practical insights into the ...

The liver is an organ with many facets, facilitating numerous physiological functions. This chapter concentrates on the role of the liver as an immune organ, with a special focus on the unique role of each cell type that builds the liver. The hepatic sinusoids are the interface between the blood (and thereby the rest of the body) and hepatocytes, and host several cell types intimately involved in ...

This study aims to identify factors that are important to improve the retention of foster parents, which is crucial to meet the increasing need for good and stable foster homes. Using data from a survey conducted by the Norwegian Foster Homes Association, we assessed which variables could predict the willingness of foster parents to take on the same foster care placement again. Multinomial logistic ...

Crystal plasticity models enhanced with coupled or uncoupled damage and fracture criteria give an opportunity to account for the role of microstructure in ductile fracture, most directly representing the local variations of stress and strain fields inside and between the grains, voids and particles. Some computationally efficient crystal plasticity, damage and fracture models have recently been ...
