Matematisk ekvivalens i en femteklasse - en kasusstudie
2017
Masteroppgave matematikkdidaktikk MA502 – Universitetet i Agder 2017 This master thesis is a study of a fifth-grade class and their understanding of mathematical equivalence and if their understanding affects how they solve algebraic word problems. Within their understanding of mathematical equivalence the equal sign plays an important part. This study is based on former research about the main topic (Chesney & McNeil. 2014; Kieran. 1981; Knuth et al. 2006) that detected many pupils in elementary school with an operational understanding of the equal sign. Therefor the pupils have misconceptions about the meaning of the equal sign not being a relational mathematical symbol, but they view the…
On concept images of monotonicity of Finnish secondary students – with comparison and reference to tertiary students
2017
Master's thesis Mathematics Education MA502 - University of Agder 2017 This study is titled “On concept images of monotonicity of Finnish secondary students – with comparison and reference to tertiary students”. The aim is to examine: (1) What kind of aspects of monotonicity are present and, possibly, dominant in the upper secondary school students’ (advanced level) concept images? (2) What are the most typical misconceptions and deficiencies in mathematical reasoning that the participants have concerning monotonicity? (3) To what extent do the results and answers to (1) and (2) compare with the results of university students? This thesis makes use of the study of Tossavainen, Haukkanen and…
Tiendeklassingers problemløsningsstrategier i matematikk : En studie av et utvalg tiendeklassingers strategibruk under arbeid med tre problemløsnings…
2017
Masteroppgave matematikkdidaktikk MA502 – Universitetet i Agder 2017 In this study I have looked at a sample of tenth graders and the types of strategies they apply while attempting to solve three problem solving tasks in mathematics. According to the national Norwegian mathematics curriculum, students are supposed to be able to apply problem solving strategies flexibly and efficiently by the time they finish grade 10. My impression is that mathematics teachers in general tend to put more emphasis on other goals and learning outcomes, the ones that will be tested in particular. With that as a backdrop, I wanted to investigate how students undertake different kinds of problem solving tasks; …
Motivasjon ved bruk av digitale verktøy : Hvordan kan bruk av digitale verktøy påvirke motivasjonen til elevene i matematikk?
2017
Masteroppgave matematikkdidaktikk MA502 – Universitetet i Agder 2017 The theme for this master study is motivation related to the use of digital tools. In this thesis, motivation is about what motives lie behind the pupils’ behaviour, and what influences the pupils to act a certain way The aim with this study is to see if the pupils’ motivation is influenced by using digital tool in mathematics education. My research question is: How can the use of digital tools influence the pupils’ motivation in mathematics? In order to answer this, I have looked at the following questions: 1. Is there a connection between the pupils’ understanding of mathematical concepts and the pupils’ motivation in ma…
On the existence of solutions to the higher order : Korteweg de Vries-Burgers equation

Master's thesis Mathematics MA503 - University of Agder 2019 Vi studerer eksistensen av løsninger til den høyere ordens Korteweg deVries-Burgers likningenut+ 2uux−uxx+uxxxxx= 0. Ved ̊a jobbe medestimater i Sobolev rom finner vi at det eksisterer unik løsning i SobolevrommetHsfors >1/2. Ved ̊a bruke det relativt modderne Bourgainrommet klarer vi ̊a redusere denne verdien betraktelig, og vi viser at deteksisterer løsninger iHsfors >−2.
Calcium Carbonate and Phosphate Reference Materials for Monitoring Bulk and Microanalytical Determination of Sr Isotopes
2017
In situ laser ablation analyses rely on the microanalytical homogeneity of reference materials (RMs) and a similar matrix and mass fraction between unknown samples and RMs to obtain reliable results. Suitable carbonate and phosphate RMs for determination of Sr isotope ratios in such materials are limited. Thus, we determined Sr-87/Sr-86 ratios of several carbonate (JCt-1, JCp-1, MACS-1, MACS-3) and phosphate (MAPS-4, MAPS-5, NIST SRM 1400, NIST SRM 1486) international RMs using dissolved samples and two different multi-collector inductively coupled plasma-mass spectrometers (MC-ICP-MS). Our Sr isotope data are in agreement with published data and have an improved measurement precision for s…
Design of a VR application for pilots as a complementary tool for procedure training of Abnormal Operations
2021
Master's thesis in Multimedia and educational technology (MM506) The aviation industry has been amongst the early adopters of VR for educational purposes, even since the very beginning of VR’s technology establishment and throughout its further development. Flight simulators are invaluable as they let pilots and instructors replicate any situation for learning full control over the plane and improve situational awareness without paying the price of life-safety if using an actual aircraft. Abnormal operations and their procedures are a key subject of safety training, where pilots have to understand and memorize particular orders of actions in order to solve a dangerous situation on board. A …
VR formidling av en kunstnerisk opplevelse : Dette prosjektet er en interaktiv kunstinstallasjon laget i VR for Sørlandets Kunstmuseum
2021
Master's thesis in Multimedia and educational technology (MM506) I denne masteroppgaven har vi laget en VR-simulering for Sørlandets Kunstmuseum i Kristiansand. Ønsket med denne formidlingen var å vekke kunstinteressen hos publikum og undersøke om dette kan være et medium som kan bidra til økt museumsbesøk. Prosjektet har tatt utgangspunkt i fire verk som er malt av den norske kunstneren Reidar Aulie. Det har blitt utført en metodetriangulering brukeranalyse med VR-simuleringen og tradisjonell kunst, som har vært med på å dra sammenligninger mellom de to ulikeformidlingene. Dette har vært med på å bekrefte eller avkrefte vår hypotese; Bruk av VR i formidling av kunst vil bidra til større in…
Investigating Motion Sickness in Racing Simulators using Virtual Reality and a Motion Platform
2021
Master's thesis in Multimedia and educational technology (MM506) Motion sickness has been a downside of virtual reality since its beginning. According to the "Sensory conflict" theory, simulation sickness and cybersickness often occurs due to the feeling of self-motion. This thesis aimed to investigate if a motion platform could mitigate simulation sickness. By using commercial available motion platform and virtual reality headset, the experiment had three conditions, one without any added motion, one with motion and the last with increased motion. Participants were put in a complete racing set to drive an Edge 6D motion simulator in Asseto Corsa. The participants drove a high-speed car for…
Real-time video transmission in UMTS
2001
Masteroppgave i informasjons- og kommunikasjonsteknologi 2001 - Høgskolen i Agder, Grimstad Universal Mobile Telecommunication System is denoted as a 3rd cellular system and has been designed with the objective to be a system with global coverage. With the major improvement of in bandwidth capability the Universal Mobile Telecommunications System will be able to support real time multimedia services. This thesis starts with a presentation of the possible video services that can be exploited in third generation cellular systems. Video services are known to be bandwidth consuming and have rigid requirements to the real time requirements. Though the major increase in available bandwidth in the…
