Statistisk analys av en genetisk studie av typ 2 diabetes
The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

Vad gör vi med texter? : Textarbete i en årskurs 3
????Enligt styrdokumenten skall elever rustas inför dagens samhällsliv, fortsatta studier och kommande arbetsliv vilket förutsätter att eleverna kan möta och förstå texter av olika slag. För att klara de nationella proven i åk 3 krävs att eleverna behärskar olika texttyper och vi vill med denna studie se hur arbetet med olika texter i en åk 3 ser ut samt vilka relationer mellan klassrummets textarbete och styrdokumentens intentioner vi kan utlä-sa. Vi är även intresserade av om undervisningen kring texter är inspirerad av literacy-forskning eller en mer traditionell syn på läs- och skrivinlärning. Vi tänker oss att denna studie kan leda till att verksamma lärare och lärarstudenter får upp ögonen för hur arbe-tet med olika texter kan se ut för att uppnå styrdokumentens intentioner.
Matematiskt innehåll och förmågor : Lärares tankar om en uppgift i matematik
Lärare planerar undervisning och väljer vad eleverna ska arbeta med. Denna studie syftar till att undersöka lärares tankar om vilket matematiskt innehåll elever möter samt vilka förmågor elever tränar i arbetet med en uppgift i matematik. Studien genomfördes genom intervjuer med fem lärare som fick svara på frågor kring en uppgift i matematik. De övergripande frågorna handlade om matematiskt innehåll och förmågor, men även uppgiftens koppling till Lgr11 efterfrågades. Lärarnas svar kopplades till de specifika kunskaper som behövs för att undervisa i matematik.Studien visade att lärarna i hög utsträckning sorterade in uppgiften inom området kombinatorik och att de framförallt såg uppgiften som en problemlösningsuppgift.
Med en fot i varje värld - en studie av medie- och informationskunnighet inom svenskämnet
I dagens medielandskap lever många människor en stor del av sitt liv genom digitala medier, något som även påverkar skolvärlden. Denna studie undersöker den digitala utvecklingen i relation till lärarrollen och svenskämnet. Det empiriska materialet består av kvalitativa intervjuer med lärare som arbetar med medie- och informationskunnighet (MIK) inom svenskundervisning och skolutveckling samt en kompletterande intervju med Statens medieråd. Syftet med studien är att genom svensklärarnas upplevelse av att arbeta med MIK försöka förstå den digitala utvecklingens betydelse i relation till svenskämnet. Min hypotes är att dagens lärare behöver öka sin medie- och informationskunnighet för att kunna möta elevernas behov och kunna utföra sitt allt mer komplexa demokratiuppdrag.
Norska och Svenska pedagogers uppfattningar om arbetet med läs- och skrivsvårigheter i barnehagen/förskolan
AbstractThe purpose of this study is to illuminate if the preventive practices and the identification of early signals about reading and writing difficulties is different between two Norwegian and two Swedish teachers' work in preschool. Research questions focused on the differences as well as similarities between Swedish and Norwegian educators working preventively current literacy in preschool, and their efforts when they identify signals to reading and writing difficulties.The study has been conducted through interviews with four female teachers, two who work in Norway and two in Sweden.Swedish and Norwegian teachers work preventively on reading and writing, analysis resulted in three categories; books in text and pictures, words and rhyming chants and songs. No differences between Norwegian and Swedish pedagogues? prevention methods could be identified, however Norwegian teachers put more focus on rhythm and rhythmic pat exercises than the Swedish educators.The conclusions are that the Norwegian teachers mention more preventative approaches and early intervention for children with suspected dyslexia, than the Swedish teachers in the study makes. The Norwegian teachers also seem to have access to more expertise in connection with suspected dyslexia, compared to the Swedish teachers.
y måste bero av x ? gymnasieelevers förståelse av det matematiska begreppet funktion
Objective: The aim of the study is to describe pupils' understanding of the mathematical concept of function. How do pupils define the concept of function? What images of the concept of function evoke when they solve tasks, which involve identifying and constructing functions?Theory: A student's thinking about a mathematical concept depends on more than just the formal definition of the concept; therefore Tall and Vinner introduce the term concept image to describe the role cognitive structures play when students learn about concepts. The cognitive structure includes all mental images, associated properties and processes that an individual associates with a given concept. According to Sfard, an individual's understanding of mathematical concepts may have different character: an operational conception, where a concept is conceived as a process and a structural conception, where the given concept is conceived as an object, that is, as a whole.Method: 16 pupils at the Science Program at two different upper secondary schools inSweden answered a questionnaire on the mathematical concept of function.
Modersmålsundervisning, läs- och skrivutveckling i Sameskolan : Lärares erfarenheter och arbetsformer
The overall aim of the study was to take part of teachers' experiences and work force mother-tongue education and literacy development in the Sámi School. The study was conducted through interviews with twelve teachers who teach at two Sámi schools. The focus has been on looking how to work with native speakers teaching at the Sámi School, what factors promote / hinder students' development of their first or second language, and the importance of collaboration between the schools` various professions work with multilingual students reading and writing skills. Through interviews of various categories of teachers, I have tried to visibility problems of the education of minority language children and their reading and writing skills. I discuss the teaching, the importance and the lack / availability of communication and consensus between different categories of teachers.
Reklam och kritiskt tänkande i gymnasieskolan
I mitt arbete vill jag visa på hur man med hjälp av reklamanalys kan uppnå läroplanens för kritiskt tänkande i gymnasieskolan, samt ge eleverna en möjlighet att utveckla en förmåga att kritiska granska media. Detta sker först genom en teoretisk ram och här utreder jag begreppet media literacy och genom att finna en definition på vad kritiskt tänkande är. Sedan lyfter jag fram två pedagogiska verktyg som kan användas i arbetet med att analysera reklam, semiotisk bildanalys och textanalys. Slutligen gör jag en analys av en reklamannons och gör pedagogiska och didaktiska kopplingar till analysen. Jag visar genom mitt arbete varför det är viktigt att odla kunskaper och förmåga att kritiskt granska medietexter, och vilka pedagogiska verktyg man som lärare kan rusta sig med..
Ungdomars fysiska aktivitet och dess betydelse för prestationen i skolan
This study where designed to investigate if there are any positive relationship between the extent of physical activity during adolescent's leisure time and the academic performance, and also if there are any negative relationship between the academic performance and the time spent in front of the television or computers. Another part of the study tried to find out if physical activity has a direct and immediate influence on the performance in school. 91 pupils (51 girls and 40 boys) in the 8:th year of the Swedish primary school, from three different schools participated in the study. All 91 pupils first responded to a questionnaire concerning there activities in leisure time. They where then tested in a mathematical test and the results where compared with the extent of physical activity and TV/computer time they had stated in the questionnaire.
Förskolebarns matematik
This report is a qualitative study on children aged three to five years who are in the Swedish preschool. The purpose of the study is to investigate how five experienced preschool teachers view the way children between three and five years acquire basic mathematical concepts, basic numeracy and geometry. The aim is also to find out whether teachers feel that the size of the group of children affects their learning.The study contains information about what preschool teachers think about the way children learn mathematics and how the size of the group of children affects this learning. From the results it can be seen that children learn Mathematics, both in everyday situations and when playing. Moreover, the group size does not seem to affect the mathematical learning of the child.

Syftet med den här studien är att undersöka högläsningens funktion i förskolan. Genom intervjuer med förskollärare och observationer av förskollärare högläsning i barngrupp vill jag skapa förståelse för hur högläsning kan användas som ett pedagogiskt redskap i förskolan. Mina frågeställningar är:
1. Hur gestaltas högläsningen i förskolans praktik?
2.
Kan man räkna till 100, kan man mycket : Barns tankar, funderingar och förståelse kring matematik
This study was designed to describe and understand how children perceive and explain mathematical situations. During our work based training we have met several students who have been insecure in the subject of mathematics and therefore come to think that it's difficult and boring. The questions we have asked ourselves are why and how this insecurity occurs. In preschools around the country teachers actively worked to create opportunities for children to meet and discover mathematics. The question is whether the teachers are aware of how children perceive mathematics and how children think in mathematical situations. We chose to conduct a qualitative study using different methods of data collecting in order to approach the children's world.
Laborativ matematik : - Fem pedagogers syn på laborativ matematik
The students are usually eager to develop their mathematical learning. However, the Skolverket can see that this eagerness passes in the early years of school. A study shows that a varied mathematical education creates enthusiasm to learn, which can decrease the negative view of mathematics.The purpose of this study is to see how five pedagogues use laboratory mathematics, their approaches to laboratory mathematics as well as to find out their role in the laboratory education. The result of the study is based on interviews with the pedagogues, who are all teachers for students in year F-3. All of the pedagogues work in a laboratory way, but to different extents.The study shows that the pedagogues aim to make the mathematics as concrete and everyday as possible.
