Språkinlärning-medvetenhet och reflektion. : En komparativ textanalys av fyra lärarhandledningar i spanska för grundskolan.

This study is about language learning and language development. The purpose of the survey is to investigate how current learning theory and language research reflect on teaching instructions for the teaching material in spanish, with focus on the student´s awareness and reflection.The survey is based on a comparative textanalysis of four teaching instructions for the seventh year in the nineyear compulsory school.The result show great variations between the teaching instructions, regarding execercises as well as instructions. A theoretical approach and an explicit connection to research is something that is constantly missing in the instructions to the teachers..

Hur ser framtiden ut för OCR?

Examensarbetet handlar om OCR (Optical Character Recognition). OCR-tekniken går ut på att konvertera inskannade bilder från maskinskriven eller handskriven text (siffror, bokstäver och symboler) till datorformat. Syftet med detta examensarbete är att utforska OCRs framtid och vilka användningsområden som finns idag för tekniken. Det intressanta är att se hur OCR klarar sig när mer och mer material är digitala. Genomförandet till detta examensarbete har gjorts med information från böcker, Internet, mejl och genom att tittat närmare på ett företag inom den grafiska branschen som använder sig av OCR, nämligen Aftonbladet. Jag har även testat ett OCR-program, ABBYYs FineReader 8 och gjort tester med några testteman, exempelvis matematiktest och olika tester på artiklar från några tidningar. Mina slutsatser är att OCR har en framtid men tekniken har en del förbättringsmöjligheter, exempelvis tolkning av handskrivna texter. OCR kan finnas kvar även när mer och mer material blir digitala om det integreras i befintliga tekniker, som i ett spam-filter för att tolka texten i bilden.

Asperger syndrom-en studie av två aspergerenheter

The objective of this project is to study how two asperger units, one at a junior school and one at a senior-level school are carrying at their work. I have interviewed one pedagouge at each unit to find out how they organize the education at the units and how they work to develop the students' social skills based on the students' functional handicap. The interviews showed that the following factors are providing the foundation for the pedagouges' work with the students: knowledge of the Asperger syndrome and the symptoms shown by each individual, the pedagouges being explicit and well structured as a professional and as adult combined with him/her being humble and showing respect towards the students and self reflection.Keywords: Asperger syndrome, functional handicap, social interaction, attitude..

Ett kommunikationssystem för fiberoptisk överföring av bilddata förvärvad av en miniatyriserad undervattensfarkost

This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

Yrkespersonlig utveckling på Musikhögskolan i Malmö - En undersökning av lärarstudenters tankar kring självreflektion i lärarrollen.

The aim of this thesis is to investigate whether personal development, from the professional perspective, could be a relevant part of the music education department at Malmö Academy of Music. The thesis explores whether students would gain a better understanding of the professional teacher's role through personal development, and also the kind of educational structure that would be most suitable to achieve this understanding. A qualitative focal group interview was used as a method, and the participants where four students at Malmö Academy of Music. The results show that the students generally would be open-minded to integrate personal development in their educational program, and they also have a lot of interesting ideas regarding how a framework for the integration of personal development in the educational program could be structured. A number of suggestions how to integrate self reflection in the educational program are presented in the thesis.

Pedagogiskt drama ur ett radikalt perspektiv

In this development essay, we are trying to answer how drama studies in education could develop as a subject. Through participation observations and drama lessons in a development group we investigated how drama could develop within multimodality and how this new thinking could promote the identity among the youth. Two different drama lessons and one test lesson constitute our qualitative method. The methods we mainly used were participation observation and reflection. Through Lalanders and Johanssons, Skolan och den radikala estetikens and Ziehes theories we are trying to answer our questions.

Medveten lärare? : Om självreflektion i undervisning

In this paper I have examined how aware teachers are of their influence on pupils development. The method I´ve used are interviews with three teachers and one pupil each aboutMusicality - how do the teachers and pupils look at the concept musicality generally and personally?Influence I- do the teachers believe that their thinking about musicality influence the pupils self-confidence and development?Influence II- do the teachers think that other pedagogues have influenced them in their teaching and thinking?My main results show that both the teachers and the pupils have similar apprehensions as their teachers, which points towards that influence can exist. The basis is however too limited to make any extensive generalizations.The conclusion of the paper is that we have to be aware of how we influence our pupils. They carry this ?knowledge?, whether it is positive or negative, all their life..

Optimering av driftläggningar i Fortums nät

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

To be or not to be : en kritisk studie av vår teaterkanon,och dess eventuella påverkan bland kvinnliga dramatiker idag

Our theatre tradition has a long history where men have written most of the plays. If we want that the theatre should be a place, which should be built as much around womens experience as mens experiences, how can we relate to the canon? This is a study based on questions around our theatre tradition. Three women dramatists have been asked questions like: What do you think about the classics? About the women roles? Do the classics inspire you, in your writing? Is there a difference in being a female dramatist than being a male dramatist? Femi-nist theatre- theories have been used to guide us through the canon.

Kristen etik i en nazistisk kyrka : En analys av Deutsche Christens etik

This is an analysis of the ethics of the Deutsche Christen, a pro-Nazi christian movement in the Third Reich. The movement was a part of the German protestant church and attracted as much as one third of the church members. They incorporated Nazi symbols in the church activities and aimed to ?cleanse? the church from what they called jewish influenses. It is debated if a group that supports Nazi ideals can be considered ethical, or even christian, but this analysis examines their etchics and raises the question if the ethics of the Deutsche Christen can be compared to other christian ethical models.

Studier av nitreringskinetiken för järn-kromlegeringar i
ammoniak-vätgasmiljö

Kinetiken för nitrering av en järn-kromlegering med en gasblandning av ammoniak och vätgas har studerats vid temperaturer mellan 500°C och 600°C. För ett gasatomiserat pulver (Fe-7%Cr) har inverkan av syrepotential (H2O/ H2) och olika förbehandlingar (förreduktion och förnitrering) studerats med hjälp av en termogravimetrisk metod. Dessutom har laserablering som förbehandlingsmetod för nitrering av solida ytor studerats med hjälp av GD-OES-analys (Glow Discharge Optical Emission Spectrometry). Resultaten har diskuterats och tolkats med avseende på faktorer som kan påverka ytreaktionens hastighet, kärnbildningsförhållanden samt diffusionsvillkor. Syrepotentialen har visats påverka nitreringshastigheten via komplicerade samband mellan syrepotentialens storlek, kvävehalt i materialet och nitreringstemperatur.

Entreprenöriellt lärande Utvärdering av ett utvecklingsprojekt

Abstract This study is an evaluation of a development project, seeking to work for entrepreneurial learning, starting from John Hattie's findings on the significant factors for visible learning. The study is based on action research a method together with a questionnaire, focused interviews and observation, by the issue of How do students perceive entrepreneurial learning? The results show that the methodology contributes to a more active learning and greater work satisfaction among students. The results also reinforce the thesis of the formative assessment and the importance of reflection for increased metacognition. The work identifies the project's educational shortcomings and strengths, and lays the foundation for further development towards full implementation of entrepreneurial learning in a secondary activity that works to prepare students with special needs for the labor market..
