När delar blir till helheter eller helheter blir till delar : En studie om olika läsinlärningsmetoder

AbstractThe present thesis examines reading acquisition. The aim of the study is to gain a deepened understanding of various methods used for reading acquisition, how teachers? are dealing with these methods and what aspects require special attention. The overall research question of the thesis is: How can one assess children?s future reading ability and identify a method that is appropriate to this ability? The overall aim leads to several more specifically addressed issues.In the theoretical part, different perspectives and theories about reading acquisition are presented along with different methods for how to work in order to facilitate reading.

Jämförelse av två mätmetoder för mindre gasvolym

Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

A comparison of transporters? paddle use when unloading pigs at slaughter

Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.

Utveckling av en ytmonterad fördelningsmätare som underlag för individuell debitering av vattenförbrukning i fastigheter

The master thesis, conducted at Metrima AB, concerns the development of a non-intrusivedistribution meter as a basis for individual tap water billing in apartments.The project is conducted in response to the market interest in individual tap water billing inapartments as an answer to environmental concerns regarding water consumption. Due to thehigh installation cost of traditional water meters, a new method of determining waterconsumption, without having to cut water pipes, is proposed.The proposed method distributes the total water consumption for an apartment complex toindividual apartments according to distribution meters, measuring water run-time, in eachapartment. The water run-time is estimated by measuring the water pipe?s outward vibrationsand temperature changes.A test environment was established and a prototype built, using a tilt- and vibration sensor forvibration sensing and a precision temperature sensor to measure temperature changes. As bothsensors work well in the test environment, further testing was done in 3 apartments for aduration of 5 days.

En studie i användbarhet: En kritisk analys av användbarhetsstudier i biblioteks- och informationsvetenskap

Usability studies are not a central field of research in library and information science. Although literature in library and information science treats the importance of usable user interfaces quite extensively, the literature does not significantly treat potential problems in measuring usability. The aim of this master thesis is to investigate, through a critical analysis, the methods used when conducting usability studies in library and information science. The critical analysis is based on potential problems in measuring usability identified through a literature review from the field of studies Human-Computer Interaction, the concept of usabilitys original domain. The material which is to be analysed, is chosen from one library and information science journal Journal of the American Society for Information Science and Technology.

Att förbättra elevers läsförståelse : Hur lärare undervisar elever för att eleverna ska nå ökad läsförståelse i årskurs 5

The purpose ot this study is to investigate how two teachers of fifth grade say they are working with reading comprehension in their teaching. Furthermore the aim is to investigate how the teachers' instruction in reading cmprehension expresses itself. The study was conducted from a teachers perspective and the questions that the stydy will answer are: How do two teachers in fifth grade believe they should teach in order to develop reading comprehension among their own students, and what methods, activities and materials are the teachers using in order to develop students' reading omprehension in the educational practise. The methods used during the study were interviews and observations. The observations were made in order to complete the picture from the interviews.

Agila metoders påverkan på testare

To assure good quality the software needs to be tested to find errors and to verify that the programme meets the customer?s expectations. Traditional methods are usually used in software development and means that a number of predetermined steps are followed. By using agile methods the development can more easily be adapted to the changes on the market. With these methods the testing is carried out continuously throughout the project.

Kyrkan som immateriellt kulturarv En studie i kulturvårdens förhållningssätt till liturgiska värden

This master thesis aims to examine the methods of the conservation field and their visionabout maintenance and change, in terms of liturgical values. This is to be able todetermine if there is a need to develop the methods that the field of conservation has tosafeguard the intangible cultural heritage of the churches.This is mainly a literature review, focusing on different tutorials from the Swedish nationalheritage board, and different texts on liturgy aswell as Unesco's Convention for theSafeguarding of intagible Heritage (2003), ratified in Sweden in January 2011. A casestudy of the practical work has been carried out on three churches that have undergonechange. The application process and the results were important for this study.The conclusion is that the conservation field have ambitions to preserve the liturgicalvalues, but they do not have sufficiently developed methods to do so. Nevertheless, itappears that most cases of change in churches, increases the liturgical values..

Slumpmässig Informationssökning eller ?Jag talar hellre om inspiration?. Skådespelares slumpmässiga informationsanskaffning

The aim of this study has been to investigate actors? methods for acquiring information that is necessary for their profession, with a focus on the more random methods they might possibly use. The study is based on the following questions: What information needs do actors have in relation to their profession? Which methods do actors use to procure information? Which information systems do actors use? What role does the library play in the actors? acquisition of information? Through an interview study with 10 informants a picture is formed of the actors? information behavior. With the help of theoretical ideas regarding random methods of acquisition, we describe which information needs actors have and how they acquire that information.

By using a strategy based on making every operation as safe as possible, series of the game have been simulated. The size of the playground is four times four squares.

Bråkiga barn -Att förstå och bemöta utagerande barn i förskolan

Inspired by the article Special support on dubious grounds published in Teachers News (2010), we chose to examine the methods and procedures regarding acting out children without diagnosis. In preliminary work, we discussed the various forms and causes of acting out behavior among children in preschool and supervision and conflict management. The topic seemed relevant since we on several occasions experienced a feeling of inadequacy and lack of knowledge in our educational role both in teacher training placement time and during our working years as supply teacher and graduated child minders. Based on our past experiences and interests of acting out children without the diagnosis, work limited extent and time aspect for the course of the work we chose to only interview three pedagogues. Through the interviews, we wanted to compare these three pedagogues description of their work around acting out children without diagnosis in relation to accepted theories such as structure and clarity.

Utformning av sidoområden med hänsyn till vägens livscykelkostnad

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

Gapet mellan teori och praktik i pappersprototypande : en studie i diskrepans mellan det ideala arbetssättet akademin förespråkar och hur praktikern faktiskt arbetar

This study presents an alternate viewpoint to the strive to overcome the gap between research and practitioners within paper prototyping in interaction design. Earlier research identifies three aspects of this gap, which is:Practitioners being unaware of interaction design methods and theoriesPractitioners being aware, but choosing not to apply these methods and theories, due to time, budget and constraints of labourPractitioners and research having different perspective on similar design issuesOur study was done by carrying out qualitative interviews with interaction designers based on two digital design bureaus. One of the bureaus has an expressed link to research: the other has not. Our hypothesis is that the gap would manifest as a difference in work practice between the two bureaus.Our study shows that the two bureaus have similarities in work practice and that this work practice is based on scientific methods and theories, but is adapted to fit the client and/or the project. We conclude that the overcoming of the gap might not be necessary.
