Att bryta tystnaden: kommunikation i matematikklassrummet
The purpose of this study is to investigate how teachers approach communication in their
mathematics instruction. The communication involves concepts such as teachers'
mathematical language, incorrect answers, and various interaction patterns. In line with this,
the study also examines how these types of communication may affect students in the
classroom. Furthermore, observations and interviews were conducted with five different
teachers in Sweden using an observation scheme and an interview guide. The results reveal
that four out of the five teachers use both child-directed and adult-directed language when
addressing students at different levels of mathematical understanding.
C?RONIS BIVAXFERNISSA En unders?kning av inneh?ll, l?slighet och ?ldringsegenskaper
The aim of this study is to provide a comprehensive overview of C?ronis beeswax varnish by Lefranc &
Bourgeois; its contents, aging properties, solubility, and possible removal methods, with G?teborgs
Konstmuseum?s ?Gothenburg Museum of Art? collection as the stud??s material? The purpose of the
study is to provide a basis for decision-making regarding the treatment of works treated with C?ronis
wax varnish. The study is based on contemporary conservation theory and interpretation-based
decision-making and utilizes FTIR, microscopy, and solubility tests to examine the properties of the
varnish. The study shows that C?ronis does not appear to be harmful to the treated works and has
retained its solubility properties and transparency over time.
Vad ?r en funktion?
The concept of function represents a major part of mathematics and becomes more significant
in school during high school. Throughout history, it has been a difficult concept to define and
may create challenges for contemporary students. This literature study aims to identify students'
difficulties with the concept of function, as well as to account for how the definition of a
function has evolved historically. The literature study has been conducted through database
searches in ERIC, Education Research Complete and MathSciNet via EBSCOhost, as well as
through chain searching. The study results in identifying that students' difficulties with the
concept of function primarily include the graphical and algebraic forms of representation.
Kvalitetsredovisning och undervisning i matematik
The aim with this master thesis is to analyze a scientific material concerning the context between learning and child/student development, and factors which controls process of learning, to create an image with quality account and teaching in mathematics, which then can raise the mathematical knowledge among students.The phenomena which stand in focus for the investigation is: why there is a negative tendency for development of knowledge in mathematics, among the Swedish students that TIMSSs investigations showed in intercultural comparison within the years 1993, 1999, 2003 and 2007.The method is the ethnographical method, which is based on: analyzing scientific theories about learning child/student development, factors which controls process of learning, and factors which controls process of learning the most and qualitative empiric investigation with qualitatively analyzes the questionnaires, which is about factors which are controlling the process of learning and factors which are controlling the process of learning the most.Result of the theoretical and empiric analyzes shows that factors as school environment, attitude for subjects and teaching, controls and influence the learning. To end a unenthusiastic tendency as a negative development of mathematical knowledge among students that is shown in TIMSS investigation and to elevate the students' performance in mathematics, an elevated qualitative account and teaching in mathematics, by the factors named. Safe school environments as the intercultural meeting place, the teachers influence part to the students' subjects' attitude in mathematics and goal related grading criteria in teaching, is all required for e qualitative teaching in mathematics..
Att se sitt barn med nya ögon: en narrativ studie om föräldrars upplevelse och meningsskapande när deras barn får diagnosen autistiskt syndrom
Based on phenomenological hermeneutics and narrative theory the study explored how parents experience and create meaning when the child receives the diagnosis of autistic disorder. Interviews were conducted with eight parents and the analysis concerned both contents and form in their stories. The resulting aspects of the contents is presented in seven areas: stories about the time before the diagnosis, seeking help, receiving the diagnosis, the meaning of the diagnosis, coping, living with autism and stories about the future. The six resulting aspects of form included: chronology of the stories, creating order out of chaos, cultural norms, rewriting the story about the child, aspects of metaphors and changing perspective. The conclusion of the study is that the diagnosis serves as a way for the parents to transform experiences into a meaningful whole.
Kontaktfamiljsinsats beviljad... till vad och vilken nytta?
The purpose of this study is to describe and analyze a group of participants (social workers, contact families and the young adults who had been given a contact family as children) and monitor their experience of the intervention contact family and its goals, contents and design. We also wanted to look into what goals and guidelines are available regarding the interventions design and contents. We also looked into parts of the intervention which the participants found most useful for them individually. The method we used in our study was qualitative interviews. We compared and analyzed our results to research made on the subject and the theoretical frame.
Miljödifferentierad fastighetsskatt
It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.

En bra Chef går hem : - en undersökning av Landstinget i Värmlands chefsbrev
Internal communication is very important for the success of an organization. The county council Landstinget i Värmland is a large organization with many managers on different positions. Every one of these managers gets an email every week, with the message that a new manager letter, called Chef, is published on the intranet. With my paper I am examining what the managers think of this letter, how they use it and if managers on different positions differ from each other in opinions about and use of the letter. I want to find out if there is a need of Chef as a part of the internal communication of Landstinget i Värmland.To answer these questions, I have chosen a quantitative method in the form of a questionnaire which is send to all the receivers of the manager letter.
Effekt av karbonatisering med biogas på aska från trädbränslen

Solar energy on Swedish pig farms : a sunny story?
In Sweden there is a large interest in renewable energy but the market for solar power is still small compared to other countries such as Germany. Here many farmers produce their own electricity. The Federation of Swedish farmers have acknowledged the potential for Swedish farmer to produce electricity and there is an interest among the farmers. The agricultural branches in Sweden most suitable for solar power are pig production and poultry due to the even electricity need throughout a year. Swedish pig farmers are going through a period of unsteady profitability which makes it interesting to see whether producing their own electricity can affect the economic situation.
Hållbarhetsredovisning : En studie kring skillnader mellan granskade respektive icke granskade företag
The purpose of this study was to examine the differences between non-audited and audited sustainability reports and in that way indicate the significance of auditing to the contents of a sustainability report. The study was delimited to include three companies that create sustainability reports according to GRI guidelines, and also have changed from non-audited to audited reports.The study is an exploratory study where we started from companies that follow GRI's standard and who have changed from being non-assured to assured and certified. In order to examine any differences we have started out from corporate sustainability reports and with the basis of these latter gather those changes which may have occurred during the changeover. We therefore chose to conduct a literature review on each company's non-audited sustainability reports and compare them with each company's audited and certified sustainability reports. Furthermore our study has been made on the basis of an assessment model based on the concepts of materiality, completeness and comparability.The study showed that the audited sustainability reports in all companies were more focused and more detailed about the aspects GRI established for the performance indicators.
Mandatfördelning i Sverige
This essay will cover the Swedish electoral system with a focus on the proportional representation andthe process involved from the conversion of votes to seats in the parliament. This process consists ofseveral methods which are created by political decisions as well as mathematical formulas and is notalways perfect in terms of equalization. An increment of six adjustment seats would have made thegeneral election of 2010 more proportioned. Despite this, the Swedish electoral system is wellconstructed and the essay will highlight areas which could be subject for improvement as well asexplaining fundamental concepts of the process..
