Teachers’ awareness, knowledge and practice of information security in school
2020
Master's thesis in Information systems (IS501) We found that the teachers in our respondent schools lacked formal training on topics of information security. Most of them did not know what phishing, backdoors and keyloggers are, and many reused passwords across multiple sites. The teachers were also concerned about lacking the knowledge to properly teach their students about information security and netiquette. The principals did not consider information security to be a primary concernand the IT-department employees had varying knowledge of information security.Meanwhile the municipality has been focused on procuring hardware and softwarefor the teachers and students, and ensuring proper u…
Privacy-enhanced network monitoring
2013
Doktorgradsavhandling i informasjons- og kommunikasjonsteknologi, Universitetet i Agder, 2014 This PhD dissertation investigates two necessary means that are required for building privacy-enhanced network monitoring systems: a policy-based privacy or confidentiality enforcement technology; and metrics measuring leakage of private or confidential information to verify and improve these policies. The privacy enforcement mechanism is based on fine-grained access control and reversible anonymisation of XML data to limit or control access to sensitive information from the monitoring systems. The metrics can be used to support a continuous improvement process, by quantifying leakages of private o…

Analysis of relations between attitude towards mathematics, prior knowledge, self-efficacy, expected and actual grades in mathematics
2022
The purpose of this study is to analyse relations between students’ attitude towards mathematics, prior knowledge, self-efficacy, expected grades, and performance in mathematics among 115 firstyear engineering students. We combine two statistical techniques to analyse the data we generated by questionnaires and two tests. First, item-level modeling, in terms of confirmatory factor analysis, which we use to compute the factor scores of construct-validated measures, and to control for measurement errors. Second, composite modeling, in terms of path analysis, which we use to test the research hypotheses. The findings show that both self-efficacy and expected grades have substantial effects on …

An exploration of how social science students utilise an opportunity to learn about simulation-based research methods : A design-based study
2021
Paper I, Paper III and Paper IV is excluded from the dissertation with respect to copyright. Paper III and Paper IV is not published yet. At the core of this thesis lies an exploration of how social science students utilise an opportunity to learn about Modeling and Simulation (M&S)-based research methods. The study is framed within the Cultural Historical Activity Theory (CHAT). The thesis also utilises local theories such as the community of practice theory, the theory of objectification, and the theory of semiotic representation, and these are used to analyse, interpret and discuss the data generated in the study. During the analysis, boundary-crossing, boundary objects, tension and cont…
The resource decisions and documents of undergraduate engineering students in mathematics courses
2020
This thesis concerns a multiple case study, carried out at three Norwegian universities. The goal was to find similarities and differences between how engineering students from different university contexts used resources to learn mathematics, and how they made decisions regarding their use of resources. My project had an inductive focus, networking thematic analysis (Braun & Clarke, 2006) with the theoretical framework of the documentational approach to didactics (Gueudet & Trouche, 2009). After my analysis, I also compared my results and conclusions to those of authors who have conducted research projects with a similar focus (i.e. Anastasikis, 2018; Gueudet & Pepin, 2016; Kanwal, 2018; P…
The development of students’ mathematical competencies : The case of biology students
2023
This research focuses on the development of mathematical competencies of first-year university students in a Biology department as they engage in nonroutine open-ended mathematical tasks set in the context of biology. The research employs a scaling instrument on a modified extant competence framework to identify evidence of student competency development by exploring situations where students activate particular mathematical competencies. The scaling instrument is designed to evaluate the quality of competence activation. The research creates individual competency profiles for volunteer students who participated in a series of calculus classes addressing several mathematical areas over one …
Undergraduate students’ performance in mathematics : Individual and combined effects of approaches to learning, self-efficacy, and prior mathematics …
2021
Paper VII is not published yet. This dissertation concerns an exploration of factors that affect the learning outcomes of students in higher education mathematics. It is framed within a quantitative research paradigm in which the existence of personal factors such as prior knowledge, self-efficacy, and approaches to learning are assumed and that these factors may be operationalised and measured. The aim of this study is to investigate effects of prior mathematics knowledge, approaches to learning and self-efficacy on students’ performance in a first-year introductory calculus course for students on engineering programmes. Further, the interrelatedness of these factors and their combined eff…
Grunnskolelærerstudenters erfaring med eBok-basert undervisning i matematikk
2022
I denne artikkelen analyserer vi grunnskolelærerstudenters respons på en eBok-basert undervisningsform i matematikk. Denne eBoka besto av oppgaver med både skriftlige og videobaserte løsningsforslag. Oppgavene ble hentet fra tidligere gitte eksamensoppgaver knyttet til nasjonal deleksamen i matematikk. Formålet var å undersøke: a) hvordan studentene benyttet de ulike læringsressursene i eBoka, og b) på hvilke måter studentens bruk av læringsressursene hadde pragmatisk og epistemisk verdi (Artigue, 2002). Analysene bygger på kvantitative og kvalitative data fra en spørreundersøkelse (N = 60) om bruk av eBoka og viser at nesten alle studentene benyttet de videobaserte løsningsforslagene, mens…
