Bakgrundsbrusets effekt på kognitiv prestation samt skapandet av falska minnen : Om bullrets inverkan i öppna kontorsmiljöer

This study aimed to explore how 31 collage students' cognitive performance and their ability to create false memories were affected by the exposure of an extraneous background noise. The studies main hypotheses were based on previous research on how extraneous noise affect the cognitive ability and the creation of false memories: 1) that an extraneous background noise increases the ability to create false memories, 2) that an extraneous background noise impairs the learning of cognitive information, 3) that an extraneous background noise contributes to an increased representation of fictional words, 4) that an extraneous background noise impedes the ability to understand speech . The results showed a tendency in which false memories increased in the condition without background noise, a result which goes in the opposite direction of the hypothesis. Furthermore, the result supported the hypothesis that the extraneous background noise impairs the learning of cognitive information. The results also showed that there was no effect between the conditions regarding the representation of fictional information.

Kvalitetsprocesser och mätning av pinnfräsar : ? Empirisk studie av produktionsmätutrustning vid frästillverkning

This master thesis investigates quality procedures and measuring of solid carbide end mills, with the main focus on measuring equipment. The thesis has been written in collaboration with a special production department for solid carbide end mills at Sandvik Coromant in Gimo. The department?s needs and constraints have been the foundation of the project and the main research question is: how to measure end mills in order to ensure good quality of the produced end mills. The project has contained both a theoretical study consisting of a literature review and practical studies in the workshop with the objective to identify an end mill?s main parameters and the relationship between an end mill?s geometry and the manufacturing processes.

OMSTÄLLNINGSBEREDSKAP - En kartläggning av omställningsberedskap i kommunala förvaltningar i Västra Götalandsregionen

The study focuses on mapping how well prepared the counties in the west region of Sweden is in case of restructuring. The study explores what kind of activities and routines that contributes to prepare the organization for restructuring. The study also aims to investigate the effect of precedent restructuring, and if the counties who experienced restructuring are more prepared than others.The research within the field of restructuring characterizes of an evaluating nature and the focus has been after the restructuring occurred. There have also been a lot of studies of the negative consequences on individual and organizational level. Since downsizing is a frequently used method by management despite its consequences is it important to investigate how organizations can learn and thereby be more prepared for restructuring.

Lärstilsanalyser, till vilken nytta? : Vuxenstuderandes upplevelser av att göra en lärstilsanalys

Studiens syfte var att belysa vuxenstuderandes upplevelser av att göra en lärstilsanalys samt beskriva dess betydelse för lärandet. Vår avsikt var också att fokusera på deras åsikter om den information de fått innan analysen och det uppföljande samtalet med läraren. Vi ville även belysa de vuxenstuderandes tankar kring användbarheten av att göra lärstilsanalyser. Kvalitativa intervjuer genomfördes med sju vuxenstuderande på omvårdnadsprogrammet, förlagt till en mindre ort i södra Sverige. Det framkom att de vuxenstuderandes upplevelser av att göra en lärstilsanalys i huvudsak var positiva, trots att flertalet inte hade förändrat sitt sätt att lära i någon större utsträckning.

Kan cooperative learningmetoden STAD förändra elevernas attityd till matematik?

Genom min verksamhetsförlagda tid (VFT) upptäckte jag att matematikundervisningen huvudsakligen bestod av lärargenomgång och enskild räkning. Denna form av undervisning stämde inte med min bild av hur man skapar en bra lärandesituation för eleverna. Syftet med detta arbete har varit att hitta en undervisningsmetod som stämmer överens med min syn på effektivt lärande. Jag fann cooperative learning som är en undervisningsmodell som bygger på interaktion mellan elever och där alla elever är beroende av varandra för att lyckas. Med hjälp av enkätundersökningar ville jag se om cooperative learningmetoden STAD kunde förändra elevernas attityd till matematik samt vilken attityd eleverna hade till undervisningsmetoden.

"Jag har blivit en bättre mamma" : En studie om deltagarnas upplevelser av föräldrastöd i grupp

The aim of this qualitative study was to investigate the participants experiences of a parent support group and the effect of their participation on their parental role from a learning perspective. As the parent support group takes place as a group activity, the focus was on the individual learning processes which, in turn, are influenced by both the group itself as well as the leaders of the group. The empirical data was collected from a focus group interview with four mothers, and analyzed using empowerment and coping theories. Based on the participants´ narratives, the result showed that the parent support group had a great social and pedagogic effect on the participants. As a result of the received knowledge in the group from both leaders as well as from other participants, they felt less stressed and more confident in their parental role.

De mångbottnade männen och de enkla kvinnorna : En feministisk och genusinriktad undersökning av det manliga och kvinnliga i Stephen Kings Pestens tid

The purpose of this study is to explore specific pedagogical activities that benefit the student's verbal language development and to learn more about how our schools use teaching methods to achieve the ambitions in the governing documents in Sweden. The aim is finding the correlation between theory, research, governing documents and the educational work in our schools. This study contains an empirical survey in intention to see how teachers, pupils and school administrators experience school activities, to see if those activities are formed with the intention for pupils to reach the learning goals according to the governing documents.The aim of this study has been achieved by relating empirical data with theories and previous research on conversation analysis. Goffman's and Norrby's research on the importance of dialogue and previous research on dialogicity studied by Dysthe, Vygotsky and Bakhtin are presented. Those are related to empirical data and show that most teachers realize the importance of integrating dialogues in daily activities and in different learning contexts.

Kartläggning av kapacitetsutnyttjandet och ställtider på Stålöv AB : Survey of the use of capacity and set up times at Stålöv AB

The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented.Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production.To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events.

På riktigt : Fyra lärares erfarenheter av blogg i undervisningen

The purpose of this thesis was to find out what experiences teachers have from using a class blog in teaching. What are the advantages and disadvantages by the use of blogs in education?I have used qualitative interviews with four teachers in grades 1 to 6 who have worked with a class blog in teaching between one and three years.The study has shown that teachers' experience is that the blog serves as motivation and promotes learning for many different pupils and that, together with other digital tools is more equal. The main benefits that teacher mention is the expanded concept of text that offers multiple forms of expression and the authentic reader, which makes it more real, important and meaningful. Other benefits that come up are that it helps students to see their learning and learn from and with each other.
