There are different ways of developing a second language. The purpose of this qualitative study is to investigate whether and possibly how music, focused on singing, can improve the development of Swedish as a second language. Through interviews with three vocal teachers, from three different schools in Sweden, and observations of one of the vocal teachers, information about how they work and think about the subject has been collected. The vocal teachers teach groups of second language learners by singing songs made especially for second language learning. The vocal teachers consider singing beneficial in the development of the pronunciation and improvement of the prosody, which affects the students? capacity to sound like a native Swedish speaker.

During the milling of Sandvik Coromant?s world leading Drill with replaceable inserts,the CoroDrill880©, burrs appear around the milled surfaces. The burrs are removedusing different methods, one of which is deburring with special brushing machines thatare integrated into milling cells. The machines of the type Sinjet, use a Siemensguidance system. The deburring results are not satisfying and manual deburring isrequired afterwards.

A high quality is highly requested in today?s thinnings, since these are the base for continued value development of the forests. Thinning quality often means a minimization of damages on soil, stems and roots during the cutting. One way to reach a high quality is to set up goals that will be followed up after the cutting is made. Self-checking gives information of the machine drivers work and guarantees the customers a good quality of work.

The Swedish School Board reported in 2007 that students with a foreign background to a larger extent than Swedish students leave school without grades in one or more subjects in the ninth grade. The report also reveals that during the year 2007/2008 17 percent of elementary school pupils had the right to home language instruction. Students with an other mother tongue than Swedish are considered a separate group that doesn?t perform as well in school.My study investigates how eleven Arabic-speaking ninth-graders at age 15-16 perceive the importance of their mother tongue for learning and identity development. To this purpose I have conducted semi-structured interviews ? one comprising six students in group and five individual ? in a school in one of the suburbs of Stockholms.

This study investigates how Arabic-speaking students in Sweden use syntax and prepositions in Modern Standard Arabic (MSA), and how their writing is influenced by Swedish grammar and Arabic dialects. The focus is on identifying systematic patterns of cross-linguistic influence and variation between different groups of learners. The data consists of written translations by 30 students in grades 7?9 who receive mother tongue instruction in Arabic. All students translated the same Swedish source text into MSA, and the translations were analysed with attention to syntactic structures and the use of prepositions. The theoretical framework draws on transfer theory, interlanguage theory, and the interdependence hypothesis, complemented by perspectives on multilingualism and diglossia. These frameworks make it possible to capture both external influences from Swedish and Arabic dialects, as well as internal processes of second language development.

Lärare använder IKT i olika utsträckning i verksamheten och de har olika kompetens när det gäller hur verktygen ska användas (Skolverket 2009). Kompetens och kunskapssyn är två begrepp som är nära förbundna. Lärarens kunskapssyn påverkar hur verktygen används i verksamheten och kompetensen påverkar om läraren kan använda verktygen på rätt sätt för att skapa möjligheter till lärande. I uppsatsen studeras lärarens kunskapssyn och hur den påverkar undervisningen med IKT.  Frågeställningar:   Hur kommer kunskapssyner till uttryck i lärarens undervisning med IKT? I uppsatsen görs en litteraturstudie av ett urval av studier som tolkats utifrån hur syner på kunskap kommer till uttryck genom lärarens undervisning med IKT.

In this thesis, two real-time stereo methods have been implemented and evaluated. The first one is based on blockmatching and the second one is based on local phase. The goal was to be able to run the algorithms at real-time and examine which one is best. The blockmatching method performed better than the phase based method, both in speed and accuracy. SIMD operations (Single Instruction Multiple Data) have been used in the processor giving a speed boost by a factor of two..

Det finns flera olika varianter på språket engelska. Dessa varianter kommer från både olika geografiska och sociologiska platser. En sådan variant är afrikansk engelska. Engelska blir vanligare och vanligare i Afrika, så olika varianter av afrikansk engelska växer fram hela tiden. För en lärare i engelska är det viktigt att lyfta fram även denna variant av engelska i undervisningen.

Syftet med detta arbete var att få ökad förståelse för hur åtta specifika instrumentallärare utnyttjar möjligheterna och hanterar utmaningarna under lektioner i grupp och enskilt i cello- och blockflöjtsundervisning. Vi intervjuade åtta lärare (fyra cellolärare, tre blockflöjtslärare och en brasslärare) för att undersöka hur de uppfattade grupp- och enskild undervisning samt möjligheter och utmaningar med dessa undervisningsformer.Resultatet visar på att det är enklare att få en personlig kontakt under den enskilda lektionen och att lektionsinnehållet blir mer individuellt anpassat. Fokus på tekniken ses dock som både positivt och negativt. Relationen mellan läraren och eleven under den enskilda lektionen kan lätt bli osymmetrisk varför lärare bör försöka ?bjuda in? eleven att vara mer delaktig i diskussioner och planering.

I den här uppsatsen behandlas lärares arbete vid läs- och skrivinlärning i år 1. I dagens samhälle är det av stor vikt att varje individ utvecklar en god läs- och skrivförmåga. Forskning visar på att lärarens kompetens kan vara avgörande för att alla elever ska utvecklas till goda läsare och skrivare. Därför har jag intresserat mig för hur lärare arbetar. Jag har, genom kvalitativa intervjuer med fem verksamma lärare, undersökt hur deras arbetssätt ser ut samt tittat på vad som förenar dem och skiljer dem åt i detta arbete.

Föreliggande studies syfte är att vara en första byggsten i skapandet av ett praktiskt användbart tillvägagångssätt för interaktionsdesign som bygger på programmerad inlärning och tillämpad beteendeanalys. Litteraturstudier och logiska resonemang resulterade i en iterativ metod. Denna tillämpades sedan på fallet Dice Arena för att generera kunskap inför framtida utveckling av denna eller liknande metoder. Slutsatsen var att designmetoden är ofullständig men till viss del användbar. Designmetodens huvudsakliga bidrag var en sekvensdesign, en delmetod som strukturerade och tydliggjorde designuppgiften..

In visual programming the developer specifies her code, using visual tools. Within the range of visual programming languages lay icon-based languages, form-based languages, and diagram languages.Mediator is a multimedia authoring tool that allows the user to create interactive CD-ROM presentations, dynamic HTML pages and Flash projects, without any coding or scripting. The user can create interactivity in her project, using event driven and icon-based visual programming, through a ?drag and drop? user interface. This report intends to determine some of the qualifications of a tool of this kind, as well as its limitations.The report is based on a case study, in which a smaller software application was to be updated using Mediator 9.

Title: How do you get a pupil from Year 7-9 in secondary school to communicate in German?  Five high school teachers views on how to develop pupils oral communicative skill within the German language The aim of this essay is to explore Swedish secondary school teachers, from Year 7-9 in the German language, opinions regarding which work models and verbal strategies that are used and taught in order to foster the pupils oral communicative skill in the classroom. To achieve this aim, semi-structured interviews with five teachers are used.The results show that the teachers find that they encourage the pupils to speak German through creating possibilities for them to practise their oral language skills. The teachers also emphasize that they believe that alternating assignments in groups or pairs, where the students get the chance to be creative, activates the pupils to speak German the most. They also express an awareness for the fact that open or information questions encourage the pupils to use their creativity and speak more German.
