Anpassad undervisning till sent anlända elever : Hur ämneslärare på högstadiet anpassar undervisningen till sent anländna elever

This research paper has examined how three teachers in a Swedish state secondary school adapt their teaching to immigrant pupils aged 13 to16 who have recently arrived in the country. The study is based on observation in the classroom and interviews with the teachers. The study showed that all the teachers adapted their teaching methods in the different subjects by actively working with language development during their lessons. The methods employed included explaining words and definitions, using visual methods of teaching and setting frequent written exercises. In this way the pupils developed their language skills whilst covering the subject coursework.

"Förbrända men icke förintade" : en osteologisk analys av kremerade individer från förromersk järnålder från gravfältet Smörkullen, Alvastra, Östergötland

Cremated remains have long been regarded as a highly complex material that often provides unsatisfactory results. This essay discusses the problems that arise when methods commonly used on unburned bone material are used in a cremated skeletal material. The present essay discusses the results from osteological analysis of seven cremations from Pre-Roman Iron Age from a large cemetery in Alvastra, Smörkullen. Several methods were ultimately not applied in the present study as they were insufficient for application on the relevant material. Since the methods were inapplicable and fragments available for gender assessments too low, no sex assessments were made.

Styrkor och svagheter med problembaserat lärande-en metastudie

AbstractProblem-based learning (PBL) was from the beginning developed in medical school, but is today used in education in other programmes as well. Investigations about PBL have been conducted in different disciplines and there is also metastudies. In this paper, a metastudy of 8 bachelor degree papers have been conducted. The questions answered were: which methods were used to investigate PBL in primary, lower secondary and upper secondary school,which advantages were found in working according to the PBL method, which disadvantages were found in working according to the PBL method and did teachers and students views about advantages and disadvantages about PBL as a method differ and if they did, how? The results showed that mostly qualitative methods were used to investigate the PBL as a method, mostly abilities of social qualities and independence were trained in working according to PBL, a disadvantage was that working according to the PBL method was considered more resourse consuming than traditional teaching methods and teachers and students views about PBL did not differ considerably.

Byte av systemutvecklingsmetod : En verksamhetsnytta eller en nödvändighet?

 AbstractSystem methodology is in the very heart of system development, it is a crucial part of how you define your work, how you choose to approach the actual problem at hand and how to solve it. Researchers in the system development field has shown that not all methods in theory are in compliance with how it is practiced by the companies who use them. In our thesis we have studied a larger international IT- company and one of their local offices in Sweden, who some years back changed their system development method from a more traditional to an agile one. Our aim of this study has been to establish whether both of these methods has differed between theory and in actual use, and if so, why this has occurred and what the underlying rationality might have been to promote this change. Our questions that we sought to answer were; 1.

Statistisk analys av partiella urladdningar

This thesis concerns partial discharges in stator windings and the possibility of analyzing data using statistical methods. Partial discharges, or PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity is. A technique to measure and analyze PD that has become very popular over the last few decades is phase resolved PD patterns.

Enantioselektiv HPLC-analys med kirala stationärfaser bestående av makrocykliska glykopeptider och polysackarider

The purpose of this study was to evaluate enantioselective analytical methods by separation of the enantiomers of four drugs (citalopram, zopiclone, tramadol and methylphenidate) and their metabolites. The analyses were performed with HPLC-UV with columns whose stationary phases were based on macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2).The Chirobiotic V column showed high selectivity for citalopram and its metabolites. High resolution was obtained using a mobile phase consisting of methanol, acetic acid and ammonia. High selectivity for the enantiomers of zopiclone and its metabolites were obtained on the Cellulose-2 column using a mobile phase consisting of acetonitrile and ammonium acetate buffer.The enantiomers of tramadol were separated with the Amylose-2 column. However, changes in the pressure arose, probably caused by the additive NH4HCO3.

Nationella identiteter i det återförenade Tyskland En studie om hur fyrtio års separation av den tyska nationen i BRD och DDR har påverkat den tyska identiteten

Abstract (magisteruppsats, 61-80p)This paper is concerned with the national sentiments in the Federal State of Germany,regarding the east- and west-German cleavages, since the unification of the country in 1990.The point of departure is the nationalistic theory crafted together by the scholar AnthonyDavid Smith, which implies an ethno-symbolistic perspective on the dynamics of nations.The main question in the paper is to which extent you can consider the East- and WestGermans to be a unity, considering the past and the forty-year-division. For this reason theauthor basically uses two different sources: scientific books and the German journal DerSpiegel.Founded on Smith's theory, the study contains a broad explanation for national identities incontemporary states, which ranges from pre-modern times, when the ethnic communities werecreated, to the national world of today.The discontinuity of the German case, represented by the separation 1949-90 of the Germannation into two entirely different societies, makes it possible to draw conclusions about whichfactor that has the pivotal impact on national identities.The result turns out to be that the national historical core-values and symbols of the currentGerman state and nation are more profound than the splitting national sentiments. Thus theGerman nation is likely to recover from its Cold War break-up.Keywords: German unification, A. D. Smith, Nation and nationalism, National identity, DerSpiegel.

Berättandets betydelse i förskolan : En undersökning av pedagogers syn på och tillämpning av berättande för att främja barns språkutveckling

AbstractThis study investigates the impact of storytelling for children's language development in preschool from a sociocultural perspective. The purpose is to find what narrative methods teachers use to promote children's language development. I also want to examine whether the children are involved in the storytelling. To get answers to my questions which include what methods teachers use, narrative meaning and function, and their children's participation, I have used qualitative interviews with four preschool teachers at four different preschools.The results of my survey show that teachers use a variety of methods at storytelling. The most common methods were reading, rhymes and daily storytelling while eating.

Fl?ckreducering ? Bl? Vinranka En j?mf?rande studie av tv? efterbehandlingsmetoder vid reng?ring av glaserad keramik

This study explores the effects of two different post-treatment methods on stain reduction in glazed creamware from the late 20th century. The objects stains have been characterized by type one and type two stains which is the result of prolonged contact with food residues, were subjected to the same initial stain reduction. The two post-treatment methods examined are soaking the objects in deionized water and surface rinsing with deionized water. The comparative analysis included photographs under normal and UV-light exposure to assess stain visibility, weight measurements before and after treatments to monitor the absorption and evaporation of liquids, and observations throughout the experiment. The results revealed that while type two stains showed significant alterations after treatments, specifically after soaking, type one stains remained unaffected by both methods.

Matematik - En studie om hur sex lärare i årskurs 1- 3 resonerar kring olika val av arbetsmetoder i matematik

The aim of my study is to examine how six teachers discuss their choices of work methods in teaching mathematics, as well as the methods they are currently using and what they have based their choices on. This study also covers how these teachers approach educational planning and where they get inspiration for their teaching material, and finally the advantages and disadvantages of each method according to the teachers. To be able to fulfill my purpose of this study some questions had to be considered: How do these teachers approach the planning of studies of mathematics and where do they find ideas for their lesson planning? Which methods do these teachers use in the teaching of mathematics and what are the reasons behind their choices of methods? Which advantages and disadvantages do these teachers see in the methods they use during the teaching of mathematics? This is a qualitative study, mainly based on qualitative research interviews according to an interview guide. Six teachers, from five different elementary schools, grade 1- 3, have been interviewed for this study.

Avlivning av häst : en enkätstudie

Today there are various methods to use when euthanizing horses. Earlier the use of free or captive bullet was the most common method, but in recent decades this has changed and chemical euthanasia is now considered the most common method. The chemical euthanasia has in Sweden been dominated by the use of barbiturates. Somulose® entered the market in the beginning of the 90?s as an alternative to previous chemical euthanasia.

Anisotrop friktion - ett sätt att förhindra separation?

En slät yta som förses med längsgående rillor får ett minskat friktionsmotstånd i strömmande medier. Ytor med denna struktur används i många olika applikationer, allt från segelbåtar och simdräkter till flygplan. Även naturen har upptäckt dessa egenskaper. Hajar har en ytstruktur i sitt skin som är av liknande karaktär och med samma egenskaper. Hajskinnet har också en anisotrop friktionsegenskap med ökad friktion i ena riktningen.

Föräldrar till sjuka barns upplevelser av ambulanssjuksköterskan: En kvalitativ intervjustudie

Att vårda sjuka barn i ambulansen innebär ofta en stressad situation för ambulanssjuksköterskan. Föräldrarna kan vara mycket oroade, rädda och stressade i samband med dessa vårdmöten vilket kan försvåra situationen ytterligare. Det är viktigt att kunna etablera en god kontakt med barnet och föräldrarna i samband med dessa vårdmöten och bemöta familjen professionellt. Ambulanssjuksköterskan har som uppgift att få föräldrarna att känna delaktighet i vården av sitt barn och då behövs kunskap om hur föräldrarna upplever dessa vårdmöten. Denna kunskap kan öka tryggheten för föräldrarna och barnen i samband med att barnet vårdas i ambulansen.Syftet var att belysa föräldrars upplevelser av vården av sitt barn i samband med ambulanssjukvård.Metoden som användes i denna undersökning var en kvalitativ halvstrukturerad intervjustudie med sju föräldrar till barn i åldrarna noll ? sju år som vårdats i ambulansen under 2012.

Captr.net - Utveckling av iPhone-applikation och hemsida

Within the literature and film sciences there are clear models of storytelling and methods of creating a good story. In the game industry it's more difficult because the games are often non-linear, and games are a less established medium than the other two. With this study our purpose was to examine game developers and methods they used when creating a videogame, with focus on storytelling. Four interviews were made with representatives from four different videogame companies in Sweden. The information from the interviews was put in relation to theories regarding the structure of videogames and an established model for creating videogames.

Dolt i det öppna

Communication is a part of everyday life. The more sensitive information we handle, the more interesting the question around security of your information becomes. There are two ways of handling security around the information you want to communicate, either you control the means by which you are communicating. Or you control the way you communicate, making you able to use existing communication channels. Existing methods within cryptography enables two parties to communicate information securely.
