Tankar om pedagogrollen : en vetenskaplig essä om vad som utmärker en god pedagog i dagens förskola

In this essay I reflect on what makes a good preschool teacher today. I discuss the importance of education, the importance of experience and practical knowledge, but also the importance of capacity for self-reflection and listening. I bring up examples from my workplace, where some think more about their limitations than on what and how much they actually can. Others are more satisfied by what they can and see less of their limits. Some are also lack of the will to see differently and to do changes.

Sveplaserns användning till inventering/befästning/kontroll av vägmarkering

The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

Effektivt nyttjande av högeffektslysdioder i mobil belysning

The purpose of this master thesis has been to find different solutions to the design of a headlamp with a cluster of three or possibly four high power LEDs (Light Emitting Diodes). During the work, two different problems have been considered; how to design a lens in order to shape the light beam in a desirable way, and how to design a cooling system which will lower the temperature of the LEDs as efficiently as possible, still taking into account the geometry set by the optical solution as well as other given geometries. The results presented in this thesis are partly the outcome of a literature study, but derive mainly from a number of tests and measurements made on two test rigs and one concept prototype..

Samarbete - lek med mening : multiprofessionell interaktion och meningsskapande

The intention of this study was to create an understanding of how multi-professional interaction could convert into inter-professional collaboration, which takes advantage of and acknowledges the individual professional identity. The intention was to understand the meaning of collaboration through the study of meetings between professionals who use different symbol systems. In particular, we wanted to study inter-professional interaction from a symbolic interactional perspective with a focus on Self, Identity, Symbols, Meaning and Professional community. The employed method was semi-structured interviews with ten questions. A convenience sample was used to identify working groups composed of different professions, such as teachers, social workers and therapy assistants.

Utveckling av mobilapplikation: Med återanvändning av programkod

Återanvändning av programkod inom programutvecklingen idag finns i många olika nivåer och hjälper till att skapa en bred programutveckling. Med hjälp av objekt-orientering och arv skapas möjligheten att dela information mellan olika projekt och applikationer för att minimera risken att samma kod skrivs flera gånger. Syftet med detta arbete är att utreda vilka för- och nackdelar som finns vid återanvändning av programkod vid utveckling av en mobilapplikation. Vid utvecklandet av denna applikation till Windows Phone® har ett delat kodbibliotek kallat Portable Class Library (PCL) använts. För att utreda de för- och nackdelar som kan finnas med återanvändning, kommer programkod från en applikation för Windows Store® finnas tillhands.

Varför tvivlar jag? : En essä om att omsätta vetenskapliga teorier med praktisk kunskap

This essay is about the development process I have undergone during my experience-based preschool teacher education. I write about my internal process, about how I as a childcare worker go from assertiveness and believing in myself into fighting doubts, thoughts and feelings as a preschool teacher. The purpose with this essay is to make the difficulties with managing new knowledge and practicing it in real life visible, and at the same time overcome your uncertainty in a new professional role. The essay is based on two stories from my professional life where I, in the first one portray my actions and behavior as a childcare worker and in the second one as a preschool teacher. Based on my stories I try to answer questions as what does the individual learning process look like when going from one professional role to another in the same profession? What impact does theoretical knowledge have on practical knowledge?I have used reflection and writing as methods for my paper.

Nycklar till frihet : Hur idrott, jazzmusik och dans påverkade ett afro-amerikanskt identitetsskapande och rasrelationer i USA under åren 1925-1939.

The aim of the study is to show how children and adults are described in three picture books, examining how children and adults are portrayed in text-and-picture narrative and how this has changed over time. We have analysed how the characters in the books are presented and how the representation of children and adults has changed in our own times.The material for the study consists of three picture books from different periods, with the focus on how children and adults are described as the common point of departure. The analysed picture books are: Tomtebobarnen (Beskow 1919), Aja baja, Alfons Åberg! (Bergström 1972) and Snäll (Dahle 2008).We have arrived at the conclusion that a text-and-picture narrative is in very large measure a reflection of the outlook on children, childhood and child rearing at the time when the book was published. The result shows that the greatest change that has happened is that parents? and adults? dominance in the books has declined over the years, and that children have been given a more prominent role.

Eva och lagen - En studie av bibliska syner på kvinnor utifrån skapelseberättelsen i Gen 2-3 och lagar i Gamla testamentet

The purpose of this C-essay within the subject of religion is to form a notion as to how the attitudes towards women and their position in a theoretical biblical society might have been perceived, based upon a select number of texts from the first five books of the Bible (the Pentateuch).Since this essay was written under the framework of the teacher education programme, it is also integrated with the pedagogy subject. This manifests itself with the didactic reflection at the end of this essay, where I try to relate the subject of this essay to the teaching profession.The material, which consists of excerpts from the first and second chapters of Genesis, and aselection of the laws in the first five books of the Bible (from Genesis to Deuteronomy), wasanalysed according to an ideological model, where themes and patterns have been more important than specific word choices.The analysis showed that the views on women vary depending on who writes and who interprets a specific text extract, and the conclusion was that since laws reflect the society it is likely that they were created to improve women's status to make it as equal to the man's as possible.The didactic reflection offers suggestions for lesson plans on the themes gender, feminism andfeministic theology..

Det finns ju inga patentlösningar : En studie om kompetensutveckling i kunskapsföretag

The aim of this study is to investigate how employees in consulting companies develop their competence in order to perform their daily work. The focus is on informal competence development. The theoretical framework consists of theories concerning learning and competence development in working life, theories on organizational change and evaluation, a well as professional reflection. The methods applied are narrative research and interviews based on the assumption that knowledge about reality is only obtainable through language and communication.The main results show that competence is developed through experience, social interaction, communication and dialog with co-workers and customers. The post-modern conceptions of the rapid (technical) development and need to be up-to-date has a strong hold on the informants apprehension of working life, as does the notion of not having enough time for all the competence development they would like.

Vanans makt : Betydelsen av vana i praktiska verksamheter i naturen

AbstractOur life-experiences and our background form the way we act and the activities we are involved in. The overall purpose in this thesis has been to study what habits are to be found in different activities related to the outdoors and how these habits have been developed. Hopefully this work can contribute to a better understanding of the meaning of habits in our lives and thereby play a part in a further differentiated talk about habits and knowledge in society. The background and my theoretical approach has been three views of habits:In practice these patterns of habits are not separable so this approach should be seen as a way of making the development of habits clearer. Another purpose is to study how the following concepts can be related to habits: Reflection, master-apprentice, episte?me, techne, phronesis, interest and tacit knowledge.

Tänk om hon ville leka titt ut? : En essä om olika förutsättningar till kommunikation hos barn med flerfunktionshinder

My essay begins with a story in which I portray different communicative situations at the preschool unit Myran. The children in my story are at an early stage of development and they all suffer from multiple disabilities which inhibit their ways of communicating. Through my story, I describe how I perceive different communication dilemmas in my work place. A difficulty I cover in my essay is how the educator knows if he or she has interpreted a child correctly when it does not have a verbal communication and therefore is completely dependent on the educators? interpretations of its communication efforts.

Nationell Moralsyn? : Om betydelsen av nationell tillhörighet för ungdomars moral.

Denna undersökning syftar till att undersöka nationella skillnader i moralutveckling och innehåll i moraliskt resonemang. Studien omfattar 445 svenska och 148 amerikanska ungdomar i åldern 14-19 år. De svenska fpp är hämtade från högstadium och gymnasium i Stockholmsområdet, och de amerikanska från två katolska privatskolor i New York. Dessa tog del av ett moralfrågeformulär av Gibbs (Gibbs & Widaman, 1982; Socio-moral Reflection Measure; SRM) som är en reviderad version av Kohlbergs intervjumetod för bedömning av en individs moralutveckling och kvalitativa, moraliska synsätt i frågor rörande moral. Vid analysen förelåg inga nationella skillnader i moralutvecklingsnivå.

OCT inom ögonsjukvård : noggrannhet hos mätfunktion

Denna rapport handlar om optisk koherenstomografi, Optical Coherence Tomography (OCT), en relativt ny teknik som blivit allt mer attraktiv på sjukhusens ögonkliniker. En OCT-apparat används bland annat för diagnosticering av ögonsjukdomar lokaliserade i gula fläcken och runt optiska disken. I maj 2007 köpte Ögonkliniken på Blekingesjukhuset in en 3D OCT-1000 av märket Topcon. Hos denna OCT-apparat finns en mätfunktion, Caliper, som mäter näthinnetjocklek. Studien i denna rapport syftade till att ta reda på vad Caliper mäter, hur den mäter och om den går att lita på.

Åh, det här klarar jag! : Samtalets betydelse för matematikförståelse

The aim of this study is to investigate into the use of discussions in the classroom to help the pupils develop a deeper understanding of mathematical concepts and operations. The empirical data contain interviews with two teachers and observations from their lessons. The purpose of the interviews was to find out what importance the teachers ascribed to the ability of their pupils to talk about mathematics, and how they organised their classes to encourage mathematical discussions. With the observations, I was able to see the interaction in the classroom and hear discussions between the teacher and the pupils, as well as between the pupils themselves.The interviewed teachers proved to share my own belief in the results of researchers like Malmer (1999) and Löwing (2006) about the importance of verbal discussion, argumentation and reflection during mathematics classes. But convictions derived from the research of others are one thing, the practical application of the wisdom in the classroom another.
