The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning.  An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.

Bakgrund:Läraryrkets komplexitet och bristen på lärares teoretiska förankring öppnar för att i en variationsteoretisk ram fokusera ett lärandeobjekt som ett sätt att utveckla lärarnas lärande samt lärarprofessionen.Syfte:Syftet med studien är att undersöka några lärares föreställningar om innehållet i deras undervisning, deras föreställningar om elevernas lärande samt hur detta innehåll gestaltas under en lesson/learning study.Metod:Genom deltagande i planerings- och analysmöten samt genom observationer studeras lärarnas samtal om och deras gestaltningar av ett innehåll i vad som kan sägas vara en mix av en lesson study och en learning study.Resultat:Lärarnas samtal under planeringsarbetet och genomförandet kännetecknades av en låg grad av teorianknytning, där innehållets strukturella aspekter inte synliggjordes. I lärarnas samtal synliggjordes inte heller elevernas lärande vilket däremot kom till uttryck i undervisningssituationerna..

The purpose of my study is to examine why five primary school teachers chose to start using the method ?Learning reading by writing on computer? in their teaching. How do they perceive that the method works in their classroom and do they perceive that the method affect the children?s literacy?The study consists of a qualitative method in form of interviews with five primary school teachers and also some observations made by me in the classrooms. I will use the findings I made during the interviews and observations and contrast these to relevant literature and research that I have collected.The result of my study shows that all of the interviewed teachers had a self-interest in working with the method ?Learning reading by writing on computers? and that they also worked closely with colleagues.

Avsikten med denna uppsats har varit att undersöka om det är möjligt att bygga upp en kursmall i en lärplattform, i det här fallet It´s learning, som ska kunna användas av lärare för att bygga upp både distanskurser och närundervisningskurser. Fokus lades på att dels hitta minsta gemensamma nämnare för en sådan kursmall och dels på att vidareutveckla arbetet med It´s learning på Örkelljunga Utbildningscentrum där jag är anställd. Undersökningsgruppen var i första hand lärare med sina kunskaper och erfarenheter av undervisningen både på distans och i klassrummet, i andra hand elever med sitt behov att ha insyn i vad som gjordes, vad som ska göras, vad har man missat och vilket är resultat av deras lärandearbete i form av lärarens feedback och betyg. Metoder som användes var enkät, intervjuer och samtal. Arbetets slutsats är att man kan, med en kursmall som grund, bygga upp både distanskurser och närundervisningskurser i It´s learning, det kräver dock mycket tid och engagemang från lärarnas sida då mallen ska fyllas på med vettigt undervisningsmaterial och planeringen synliggöras för eleverna. Allt handlar inte bara om tid och engagemang, även bristande datakunskaper hos en del av undervisarna är ett grundproblem som måste övervinnas. Projektet utmynnade i att de flesta av mina kollegor började använda sig av lärplattformen, dock ej alla som målsättningen var från början. Kursmallen underlättade arbetet initialt men den stora insatsen ligger under årets lopp då varje påbörjad kurs ska fyllas på med lektionsplaneringar och digitalt undervisningsmaterial av hög pedagogisk kvalité. Nyckelord: lärplattform, utbildningsplattform, It´s learning, distansundervisning, närundervisning, kurs, struktur, kursstruktur, kursmall.

The aim of this master thesis is to examine the opinions of the students of Linköping University regarding the role of the university library in their learning process. The study addresses the student?s expectations and satisfaction regarding the library services. The questions we seek to answer are: What are the students? conceptions of Linköping University Library as a part of their learning process? What expectations do the students have regarding Linköping University Library? Does the library fulfil the students? expectations? In what way has the library?s pedagogical ambition reached the students? What are the students? opinions about the user education? The study is based on a web survey complemented with interviews.

The purpose of this study is to describe how the employee appraisal is perceived by managers, employees and representatives from human resources departments. The empirical material con-sists of 15 interviews: respondents were two representatives of the human resources departments, four unit managers and nine employees who work at a state institution or municipal management. In the study, I adopt a sociocultural perspective, with the communicative relational perspective. The latter is a special education perspective in which the interpenetration of participation, com-munication and learning emphasized.The result shows that the majority of employees would like to see that the talks will be held more frequently than once a year. One of the managers has in cooperation with his co-workers devel-oped a model based on that each year, in addition to salary talks, have an individual conversation, a conversation with each group and individual follow-up talks.

Syfte: Syftet med undersökningen var att studera lärares erfarenhet av att arbeta med learning study som modell för undervisning. Avsikten var att försöka förstå om modellen kan bidra till att öka den beredskap som behövs för att möta elevers variation i undervisningen genom att ge lärare redskap för reflektion och förändring. Syftet var också att undersöka om learning study skulle kunna vara ett redskap för specialpedagogens arbete inom ramen för en inkluderande pedagogik. Teori/Metod: Undersökningen baseras på intervjuer med fem lärare från två grundskolor,7-9. Inför studiens genomförande gjordes en auskultation i learning study, för att bättre kunna förstå dess upplägg inför intervjuundersökningen.

I begin my essay with a story that illustrates how a preschool activity organized on a modular work can be perceived. I describe how the environment has been rebuilt and modified to accommodate one large group of children instead of two smaller groups as before. Management´s justification for the change is that it is carried out to give the children better conditions for their learning, but my understanding is that it also hampers preschool-teachers´ abilities to implement their assignment.I try to understand what benefits module work by examining what well-known researchers believe is important for children´s learning in environmental and preschool teacher´s importance. When I use what I have learned to analyze my story, my opinion is that the change of the preschool activity not have just a positive impact but also entails that preschool teachers find it difficult to be present and in interaction with the children as several well-known researchers notes is important for children´s learning. I discuss how a large and rich environment at the same time can be perceived as incalculable for teachers, which can result in not all of the children being paid attention to in the preschool activity.

Syftet med denna studie var att beskriva skillnaderna i sättet som lärandets innehåll behandlas i matematik under två lektioner i årskurs 4 om ekvivalens, samt titta på om det intentionella lärandeobjektet var förenligt med det iscensatta lärandeobjektet. Studien kommer även att titta på ifall eleverna lärde det som var intentionen med lektionen samt vilken invarians och variation som skapas under lektionen. För att besvara dessa frågor används learning study som en forskningsmetod i denna studie. Studien visar att grupp 1 inte erbjöds lika goda förutsättningar att erfara det som var intentionen med lektionen som grupp 2 gjorde. Resultatet visar också att skillnaderna var väldigt små mellan de båda grupperna, men att grupp 1 i stort sett endast hade förbättrat sig på uppgiften de undervisades om under lektionen.

The information society creates new demands on the knowledge making individual; besides being literate one has to be information literate. And in the educational society there is an ongoing change from teaching to learning, the focal point being the active student and life long learning. The aim of this dissertation is to within a context of learning and teaching elucidate the relation between user education and subject education by examining what significance the academic libraries user education has for the development of information literacy within students. Some epistemological theories connected with learning is presented as well as aspects of the information search process and of information literacy. Universities and their libraries view of information literacy and the goal of their user education is being focused on in an empirical study.

The purpose of this work is to explore and illuminate the circle times function and importance of preschool by the pedagogue perspective and the circle time design in relation to children's age group composition. The study questions are:What is the purpose of circle time in preschool educational activities according to the teacher and how does the teacher look at his own role?How do the teachers plan, design and perform the circle time of small children and big children's section? What similarities and differences exist?This is a qualitative study based on interviews with four preschool teachers and observations of their circle times. Research and theories showed that the circle time is a social training, provide a sense of community and is a ritual that gives a good daily rhythm.The results of the study demonstrate that the circle time is an important routine that occurs for a short time daily in early childhood education. The circle time organizes and structures the day for both children and staff group.

Abstract The amount of evil that we can see in our world might make the thought of a kind and caring God as its creator paradoxical. This is what is generally called the problem of evil and the topic of this study. This is a litterary study which is based on qualitative analysis and hermeneutics as our method. We have chosen to research this problem with the emphasis on two different theodices. One of these theodices is written by John Hick and the other by C.S Lewis.

Background and problem discussionThe temporary employment industry has grown extensively during the past two decades since the market was deregulated. Companies today need to be flexible to meet fluctuating demand and economic climate in society which has made the market expand. When using employees not directly employed by the company there is a risk that long term effects appears that the companies have not thought of.Aim of studyTo create a model of what negative aspects companies should consider when making the decision to use temporary employees.Methodological frameworkThe study performed through an abdicative literature study and with an empirical data collection method of a qualitative approach where we interviewed five hiring companies and one temporary agency on the decision of hiring temporary employees.Frame of referenceProblem areas with the use of temporary employments were identified through four perspectives of the organization; the structural, human resource, symbolic and political perspective. The problem areas we address are organizational learning, motivation, risk of eroding human capital, belongingness and conflicts. These will be described and presented together with management control to counter the problems.EmpiricsThe empirics are focused on what aspects the companies of the study considered when making the decision to use temporary employment, what the companies? different reasons for using temporary employment are and what they do to minimize possible negative effects.Analysis and conclusionsCompanies use temporary employees mostly to become more flexible, both numerically and in their competence.

The purpose of this study is to examine how pre-school teachers think about the importance of circle time in regard to the child's language and social development from a sociocultural perspective. Furthermore the study will include what role the educators? have during the circle time.To answer our purpose we have chosen the following question:What is the role of the teachers in the circle time?What are the teacher?s thoughts about the circle time?s importance to children's social development?What are the teacher?s thoughts about the circle time?s importance to children's language development?The study is constructed on qualitative methods, where we conducted structured interviews with six preschool teachers and observed their circle time to collect our empirical material. The study is also based on Vygotsky's sociocultural perspective which says that all learning takes place through relations and interaction with other people in the cultural context you are in. The results have shown that pre-school teachers are aware of the circle time?s importance to children?s development, and purposely plan the circle time to give children the opportunity to develop both socially and linguistically skills..

The aim of this study was to determine the self-perceived learning needs in patients with Coronary Heart Disease (CHD). CHD is the leading cause of death worldwide. Poor compliance is one of the causes of rehospitalisation. Patients suffering from CHD need education in order to manage their disease and prevent readmission to hospital. As hospital stays diminish the time available for patient education is limited.
