Title:              Not just words, classroom communication about subtraction in year 2Language:      Swedish with summary in English.Keywords:     Communication, mathematics, subtraction, teaching The purpose of this study is to analyze the mathematical communication in a classroom during a lesson in the field subtraction, and to find out how students describe their perception of mathematics that is communicated in the classroom.The study consists of the observations through the videotaping of two lessons in primary school grades 2 and student and teacher interviews related to these lecture occasions.Research indicates that Swedish pupils' mathematical skill continuously deteriorates in a national and international perspective, and that student experiences of mathematics in general are negative. The literature emphasizes the importance of communicating mathematics in various forms to deepen and develop understanding of concepts and mathematical operations. Communication must be generated between teachers and students but also between student and student to have a beneficial impact for the student.Our result demonstrate the different types of communication in the classroom but that communication does not always have a clear mathematical content in spite of teachers' mathematical intentions with teaching. The result also indicates that the mathematical communication that takes place, in essence, is a one-way communication where the teacher has a great opportunity to speak. The teachers perceived as oblivious to their own ways of communicating, but stressed in the interviews with an understanding of the importance of communication learning.

The purpose of this study is to provide a description of how mathematics teachers in grades 3 choose to work with mathematics and how it affects of student performance in national tests. The categories I will use are outdoor education, textbooks, learning materials and problem solving. Laboratory materials can be everyday materials and educational materials in which pupils have an abstract understanding of the subject. This survey was conducted through interviews and observations. The survey was also conducted in relation to student performance in national math tests.

A change has occurred in terms of recruitment to teacher education. From having been an educationof high status and reputation, a reduced application rate has led to lower admission requirementsand thus that students with much lower educational qualifications entering, which in turn means thatthe education status and reputation have been reduced significantly. Mathematics, on the other hand,has always been a topic of high status and reputation. Although there are few students who chooseto study to be a mathematics teacher. By conducting a survey of students on teacher educationtoday, both with mathematics and other approaches, I wanted to get answers to my questions aboutwhat influences students' choice of education: who are the students studying to be teachers inmathematics? Do they distinguish themselves from the student teachers who studies to be teachersin other subject specializations? Pierre Bourdieu's sociological ideas about cultural capitaltransmitted from parent to child constitute the theoretical framework of the study.Early in the study, I noticed that there is a difference between students studying to be a teacher inpreschool, primary or middle school and them studying to be a teacher in secondary and highschool, especially in terms of the mathematics student teachers.

According to both national and international political regulations, the school should as far as it is possible include students with special needs in regular education. However, when implementing these political intentions regarding an including school environment, problems often arise. The aim of this studie has been to investigate the opinions of teachers and students when it comes to inclusive education in mathematics. The study has partly been based on interviews with students with special needs in mathematics. These students were included in regular mathematics groups.

In the western world, strokes are the third most common cause of death, hitting mainly the elderly population. Smoking, high blood pressure, diabetes and overweight are known risk factors for causing strokes. Previous studies show that an increased level of particulate matter, PM, is also related to an increased number of strokes. The population in this study consists of patients over 65 years old who live in Malmö. Levels of particulate matter were measured from October 2004 to April 2005 at a central outdoor monitoring site in Malmö.

 In his book Wittgenstein on Rules and Private Language (1982) Saul Kripke claims that Wittgenstein argues for a certain form of scepticism in his book Philosophical Investigations (1953), namely a new form of philosophical scepticism, a result of Wittgenstein´s idea of language as language games. Nihilism, scepticism of meaning or of concept, constitutive scepticism are other commentators´ different names of the same phenomenon. The philosophy of Wittgenstein accounts for how our words, including the words of mathematics, have no meaning and there are no a priori justified objective facts as to what I mean about a word. We follow the rules blindly and without justification. We are unable to find any facts against this proposal.

The aim of this research is to examine how the homes of children, in cooperation with the schools, are offered opportunities to communicate and discuss mathematics together with the children in relevant situations. The overall intent of the study is manifest in scientific questions with focus on how parents view the subject and the opportunities to support their children with math homework as well as possibilities to actively support their child´s mathematics progress. The paper has a pfenomenographic approach, which means that it in a qualitative way describes similarities and differences in the ways the homes perceive this issue. The examination is implemented through a survey in which responds from 73 parents in four classes have been studied. Within this study six semi constructed interviews have been conducted.

A unified model of stress and affect consciousness was proposed. The connection between affect consciousness and perceived stress was studied. Teachers (n = 19) were interviewed using Monsens affect interview, followed one month later by a questionnaire containing Perceived Stress Scale (PSS), State-Trait Anxiety Inventory (STAI-S, STAI-T) and Twenty Item Toronto Alexithymia Scale (TAS-20).Statistical analysis showed no connections between level of total affect consciousness and perceived stress. Though there were some indications of a negative relationship between affect consciousness and trait anxiety. There were also indications, using a complementary analysis, of a connection between level of affect consciousness on the subscale distress in the interview and perceived stress.

Som en del av forskningsprojektet Young Operator 2020 så syftar den här studien till att vara ett första steg mot en produkt, som med hjälp av av tekniken augmented reality ska vara en del av framtidens tillverkningsindustri. Studien utgår från kognitionsvetenskap och människa-datorinteraktion för att ha användaren och användarens interaktion med prototypen i fokus. Eftersom olika typer av användare kan behöva olika saker av ett system, kommer den här studien också att utgå från teorier om kompetensnivåer. Ett system som är användbart för exempelvis en novis behöver inte nödvändigtvis vara användbart för en expert. En prototyp har skapats som en del av ett annat projekt och den utgår från det arbetssätt som operatörer på Volvo GTO i Skövde har idag.

This thesis concerns how the power quality in the grid is affected by the connection of wind power plants. As things are at present, Fortum Distribution AB has a number of wind turbines and wind parks connected to the own grid. As the pressure on building and connecting additional wind power is increasing, so is also the interest of how the already existing wind power generation affects the power quality in the nearby distribution grids. The study is performed by direction of Fortum Distribution AB and is limited to the 10 kV/40 kV-grid in Bohuslän, Sweden. The methods for calculation of power quality are compared to the results of a number of measurements.

This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which measure of prediction one prioritizes..

One of the purposes of this work was to find out what it means to have a conceptual understanding of geometry. It describes how the geometry evolved from history and the geometry that is taught in grade one to nine and collage. The area examined was based on fundamental geometric objects for example two- and three- dimensional objects and its characteristics and especially focusing on the areas of perimeter, area and volume. The literature- review showed that the conceptual understanding was primary to developing a good knowledge of geometry. The second purpose of his study examined whether pupils achieved the goals in geometry by working with a Mathematics Book.

Christendom has under a long period of time in Swedish history been the central component in legitimating the monarchs' power, a continuous process than can be clearly observed through the customs of royal coronation and baptism rites. However, during the 20th century those close ties between the state and the church of Sweden have been dissolving at a steady rate, alongside a growing societal democratization and modernization process. Officially the monarch still had a clear constitutional power legitimated through the transcendent, but unofficially his power was in reality heavily reduced. How do the Swedish monarchy relate to a rapidly changing society and secularization process? This pilot study investigates this relation by analyzing the news reports of the royal coronation and baptism rites between 1858 and 2012 from two leading newspapers, Aftonbladet and Dagens Nyheter.

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

The purpose of this essay is to explore how social workers view a possible connection between exposure to honour violence and development of mental illness and/or substance abuse. We first heard of the possible connection from a voluntary organization who work in this field and who believe that this connection could be common. We therefore wanted to explore this from the perspective of social workers who come into contact with victims of honour violence: was this something they had noticed? How did they deal with it if it was noticed? We also asked how the possible connection could be interpreted and, supposing the social workers had failed to notice the connection, why this could be. We made five qualitative interviews with six social workers working in different contexts whom within their work come across honour-related issues.
