Elevers kognitive engasjement i matematikkoppgaver : en kvalitativ studie som bygger på oppgavebaserte intervjuer i en yrkesrettet, videregående skole
2011
Masteroppgave i matematikkdidaktikk- Universitetet i Agder 2011 The theme of this master‟s thesis is cognitive demands in mathematical tasks. There has been done a lot of research within the field, and Stein and her colleagues (2000) have developed a theoretical framework to help analyze and implement mathematical tasks according to their cognitive demand. This framework is called the Mathematical Tasks Framework (MTF) and it describes four different levels of cognitive demand. The quality of mathematical tasks has been an area of interest for me for a long time, and I decided that I wanted to follow up the work of Stein and her colleagues (2000), but I wanted to pay more attention to the c…
Bruk av video i matematikkundervisning En kvalitativ studie av produksjon og bruk av undervisningsvideoer i matematikkundervisning.
2015
Masteroppgave matematikkdidaktikk- Universitetet i Agder, 2015 The aim of this thesis is to gain insight into three teachers ' thoughts about their own educational videos in mathematics. In addition, I will examine how a course with extensive use of videos can work in practice. The teachers' production styles will be presented, both in terms of my observations and their own statements. The structure of a course with the widespread use of educational videos will be explained, and looked at in terms of observation, the teachers' considerations, feedback from students and relevant theory. Qualitative data was collected through interview with the teachers and students, in addition to observatio…
Utfordringer i matematikkoppgaver på 10.trinn En komparativ studie av to 10.trinns oppgavebøker og eksamensoppgaver i perioden 2010-2014, med hensyn …

Masteroppgave matematikkdidaktikk- Universitetet i Agder, 2015 The main goal of this study is to figure out what type of challenges and to what extent pupil can expect to get challenged when they are working in textbooks from school and on the exam after 10th grade. Mathematics is often sees in the media, and often in a negative context. Pupils are bored at school because they don’t get challenges enough or people are complaining about the bad score on the exam in mathematics in the 10th grade. That’s some of the reason why I wanted to figure out more about what kind of challenges pupils get in textbooks and to what extent they get challenges. My research question is therefore; What types o…
En ungdomsskolelærers oppfatning om bruk av praktiske aktiviteter i matematikkundervisningen
2015
Masteroppgave matematikkdidaktikk- Universitetet i Agder, 2015 The aim of this study was to illuminate a teacher’s beliefs and attitudes towards practical activities in mathematics. To reveal this, I developed a teaching plan consisting of four activities. In which the students were going to construct fraction problems, knowledge of reciprocal fractions and perceive knowledge of correlations between different representations of the same value. This representation was: fraction, decimal numbers, percentage and geometrical. The research questions for the study are: 1. How does a teacher evaluate a teaching plan emphasizing practical fraction activities? 2. How does a teacher evaluate use of p…
Matematikkundervisning i skolen - Grunnskolelærerstudenters egne erfaringer som elev i skolen
2015
Masteroppgave matematikkdidaktikk- Universitetet i Agder, 2015 The purpose of this study has been to gain some insight into how pre-service teachers experienced mathematics and the teaching of mathematics from school age up until they meet the subject in their formal education. In order to be able to do more research into this topic, I have used collected data from a complete survey. The respondents were 105 pre-service teachers, some of who have mathematics as an obligatory subject (GLU 1-7), while the rest have mathematics as a chosen subject (GLU 5-10). The students were supposed to respond to different statements in the survey, regarding personal experiences from mathematics in school. …
Learning mathematics through mathematical modelling : a study of secondary school students in Nigeria
2014
Masteroppgave i matematikkdidaktikk – Universitetet i Agder 2014 The focus of this study is to investigate the impact that mathematical modelling activities may have in the learning process of mathematics amongst observed Nigerian secondary school students. I also wish to find out in what way mathematical modelling activities may help the observed Nigerian secondary school students to see the relevance of mathematics to real life. From a pedagogical perspective, I wish to examine if the application of modelling in the learning process of mathematics may be a vehicle for the enhancement and support of students' learning of mathematics as a subject. I started this thesis by looking at some pa…
Eberlein–Šmulian theorem and some of its applications
2014
Masteroppgave i matematikkdidaktikk – Universitetet i Agder 2014 The thesis is about Eberlein-Šmulian and some its applications. The goal is to investigate and explain different proofs of the Eberlein-Šmulian theorem. First we introduce the general theory of weak and weak* topology defined on a normed space X. Next we present the definition of a basis and a Schauder basis of a given Banach space. We give some examples and prove the main theorems which are needed to enjoy the proof of the Eberlein-Šmulian theorem given by Pelchynski in 1964. Also we present the proof given by Whitley in 1967. Next there is described the connection between the weak topology and the topology and the topology o…
Schauder bases and locally complemented subspaces of Banach spaces
2014
Masteroppgave i matematikkdidaktikk – Universitetet i Agder 2014 The thesis is about Schauder basis in infinite-dimensional Banach spaces and locally complemented subspaces. It starts with the notion of bases and it proves that it is equivalent with that of Schauder basis. It follows with some general theory about bases, and gives the notion of basic sequences and equivalence of bases. It proves that every Banach space has a basic sequence. Next it gives some general theory about unconditional basis. To give an other version of the definition of complemented subspaces, we present adjoint operators and projections. We prove that c0 is not complemented in l∞. The Principle of Local Reflexivit…
Laboratory mathematics: learning equations with a double-winch as a tool
2014
Masteroppgave i matematikkdidaktikk – Universitetet i Agder 2014 Many studies show that algebra is perceived by pupils as an abstract, difficult to understand subject with almost no connections to every-day reality. Therefore, the motivation for this research was to find out what helps to make the abstract topic of algebra more meaningful to pupils and how we can assist them in discovering that algebra can be useful for establishing connections between different variables. Using mechanical tools with pairs of weights that move with different velocities could be promising for instructional purposes. First of all, the different velocities of the weights make variables and their relationship t…
IKT som læringsverktøy i matematikk : en studie av lærer- og elevrollen ved bruk av TI Interactive (og andre programmer) i 4 matematikklasser i vider…
2006
Masteroppgave i matematikkdidaktikk 2006 - Høgskolen i Agder, Kristiansand Temaet for masteroppgaven er en studie i hvordan bruk av IKT påvirker og forandrer læringsmiljøet i matematikk. Jeg har undersøkt anvendelsen av CAS-programmene TI Interactive (og Derive) i fire klasser på to videregående skoler, og prøvd å dokumentere hvordan slike dataprogram nyttes for å fremme matematisk forståelse. Bruken av CAS-verktøyet er studert ut fra både lærer- og elevperspektiv. Problemstilling: • Hvilke pedagogiske overveielser gjør læreren når han bruker IKT-programmet TI Interactive (og ev. andre programmer) som verktøy i læringsprosessen? • Hvordan lærer elevene matematikk ved hjelp av IKT-programmet…
