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.

This is an empiric, qualitative, case study of cooperation between two public organizations in Ystad, Sweden (Försäkringskassan and Ystad kommun). The aim of the study is to illuminate why they cooperate and what happen with the idea to cooperate and the organizations when they do. The theoretical tools used are influenced by institutional theory. A translationmodel is used to illustrate what the local actors do with the idea when a decision is made to adopt it and how it affects the actors. The study suggests that the cooperation in Ystad called One Stop Shop is partly done because it's a popular way of organizing public organizations in Sweden and partly because försäkringskassan, aim to upgrade their organization identity.

This is the end report of my final exam at Medieteknik. It covers the planning, work process and review of a Flash based web application that I set out to do. The goal was to create a user friendly, interactive e-shop with embedded functionality for playing music, displaying rich media content and researching possible payment solutions, to enable buying music files online. The project involved creating the user interface, the programmatic functionality of a Flash client (an SWF file). Also, setting up an Apache HTTP Server and establishing a working ?bridge? between the Flash client and the web server with Flash Remoting components and AMFPHP.

The world?s consumption is increasing at an accelerating rate and it´s produced and consumed more goods and services than ever before. A large part of people's consumption consists of clothing that is bought and discarded increasingly leading to a number of environmental problems such as global warming, pollution, loss of biodiversity and the depletion of natural assets. One way to save the earth's resources is to buy used clothing, so called second hand, instead of new ones. The store chain ?The Ants? (in Swedish ?Myrorna?) has specializing in second-hand goods and sells, among other things, clothes.

Under denna studie så hade författarna ett uppdrag från en uppdragsgivare som var att skapa en ny agil projektmetod åt denna, för att främja deras arbete med ett projekt som de genomför årligen, som heter Jobb Shop. Projektet hade under det senaste genomförandet inte genomförts med hjälp av någon särskild projektmetod. Författarna till denna studie skapade under arbetets gång en specifik agil metod åt uppdragsgivaren som de kan använda under kommande år vid genomförandet av Jobb Shop. Vid sidan av detta så gjorde författarna även en metaanalys av den nya metoden där de studerade hur den nya agila arbetsmetoden, rent teoretiskt, kan främja kreativitet och innovation. Resultatet av studien visade att den teoretiska grunden för ovanstående fråga var god, och de drog slutsatsen att agila metoder, teoretiskt sett, mycket väl kan främja kreativitet och innovation..

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.

The Squares Family is a game developed as a learning aid in mathematics. With its graphical representation of the decimal system, the four basic arithmetic operations and positive and negative numbers together with a learning agent as pedagogical approach, the game?s primary purpose is to motivate students in their learning of mathematics. Although the game is strictly based on mathematical rules it attempts to encourage students to play and work with math without experiencing it as mathematics as this is initially not obvious. The game being internationally tested on normal performing students, this project introduced the game to six Swedish students who experience low motivation for and/or difficulties in mathematics.

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.

Som väl det flesta känner till är datoranvändningen i Sverige och i övriga världen ett ständigt växande fenomen. Många ting som förut varit manuella ersätts av elektronsik data och kan nu användas och appliceras på ett väldigt effektivt vis. Elektronisk handel även kallat e-handel brukar beskrivas som skedet där man som konsument eller företag köper eller säljer varor via en internetbaseradbutik vilken är en utav otaliga grenar inom denna genre som haft stor genomslagskraft på nätet och är för det flesta ett väldigt smart, bekvämt och tidsbesparande köpalternativ. Denna rapport behandlar just e-handel och vad man som e-handlare bör tänka på vid design utav e-shopar. Eftersom man inte kan ge sina kunder samma support som i en traditionell markbutik finns det vissa aspekter att ta hänsyn till för att fånga sina kunders förtroende och intresse.

This paper presents a study of the computer game ?Minesweeper?. The aim of the game is to search through a rectangular area of mined squares without hitting any mines. By using a strategy based on making every operation as safe as possible, series of the game have been simulated. The size of the playground is four times four squares.

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.

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.

The survey Distanshandeln idag 2005, made by the Swedish postal service, tells us that web shops started to pop up in the 1990´s and began competing with the catalogue sells in the end of the decade. Ten years ago, it was said that the web shops would take over the distance trade market. Today we know that did not happen. Internet shopping accounted for 4, 2 % of all distance shopping in Sweden last year. Our inquiry is guided by the observation that the catalogue is still in use and moreover, it seems to have changed very little from when we were kids.

The retailing landscape has become even more competitive with an increasing number of store formats. One result of this can be seen within different retail-chains as they launch different formats that operate under the same name. Thus, consumers now have many alternatives and substitutes when it comes to choosing which format to shop from. This phenomenon has led consumes to shop across stores for the same brand. The objective of this study is to explain how consumers respond to various offers in different store formats and to determine whether the results differ if we compare a familiar brand with an unfamiliar brand.

Strategiska allianser eller förvärv är idag ett populärt sätt för företag att öka sina marknadsandelar och säkra den framtida utvecklingen för företagen. Detta är dock ingen enkel lösning och många strategiska allianser och förvärv misslyckas. För att undvika detta måste företagen vara medvetna om de risker som finns med denna sorts samarbeten. Strategiska allianser och förvärv innebär även förändringar i företagets försörjningskedja. Detta är den problematik som ITAB Shop Concept står inför då de nyligen har förvärvat och inlett ett samarbete med två fabriker i Tjeckien, dit de skall flytta sin produktion av IKEA:s kassadiskar.
