Vi som har skrivit arbetet har haft olika erfarenheter kring läsning av matematiska textuppgifter. Intresset växte, då vi blev intresserade kring varför det kan vara svårt att läsa en matematisk text. Syftet med studien är att undersöka hur elevers läsförståelse binds samman med läsning av matematiska textuppgifter samt se vilka inre och yttre faktorer som påverkar förståelsen. Kvalitativa intervjuer tillsammans med en kombination av fallstudier och observationer ligger till grund för metoden som använts i studien. I undersökningen deltog 63 elever och fyra lärare.

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.

To read and understand are essential competences for everyone in our society; at the same time reading comprehension among Swedish pupils is on the decline. The Swedish school must therefore try to improve their instructions to increase the students' reading comprehension. The aim of the study was to describe how three reading comprehension strategies, if possible, could improve the reading comprehension for the students, including children with learning disabilities, when reading texts of natural science in a third-grade class. The three strategies that were introduced were: to activate prior knowledge, to structure information and to record contents. The questions of the study were: How are the three strategies introduced in the classroom? Can the children with learning disabilities see any benefits for their reading comprehension when working with the strategies? How do the children with learning disabilities experience working with the strategies? Can the teacher see any benefits when working with the strategies? Is it possible to see any differences among the students' results, before and after completed intervention? Method: The results have been collected through observations and qualitative interviews, which make this a qualitative study.

It is not uncommon for math difficulties and reading difficulties to occur simultaneously. Despite this, math and reading difficulties are thought to have different cognitive profiles where math difficulties are linked to number sense; an innate ability to understand, approximate and manipulate both quantities and numerical information, whereas reading difficulties are linked to phonological ability; an innate ability to understand, create representations of and manipulate phonological information. A possible link between the difficulties is that phonological abilities also could affect mathematical ability. Support for this comes from studies where comorbid math and reading difficulties are associated with more severe difficulties in arithmetic ability compared to those with isolated math difficulties. The purpose of this study is to examine whether isolated math difficulties, isolated reading difficulties and comorbid math and reading difficulties can be linked to deficits in number sense, phonological ability or both of these, and whether comorbid math and reading difficulties differ in performance in mathematical tasks compared to isolated math difficulties for children in second grade.

This work is an exploration of a method and how to find balance between it and its contents. One part consists of a technical study on how to use UV light to yellow distinct surfaces on paper and the other is about how to find use of the method. The common denominator is determined as the consequence of the relationship between light and time. The result is three images that shows various traces of time with time as a graphic expression..

This study is based on the will to understand the importance of a specific theory within social work. From the concept of neo-liberal governmentality, the aim is to critically examine and discuss how governance and self-governance is manifested in social work methods and interventions, exemplified by the theory cognitive-behavioural therapy (CBT). This will be accomplished through an analysis of:? How governance (and self-governance) is manifested in text through the advocacy of CBT and methods based on CBT.? How (governance and) self-governance is manifested in text through the contents of CBT and methods based on CBT. The study has a deductive approach including the hypothesis that the discourses inherent in social work methods and interventions, exemplified by the theory of CBT and methods based on CBT, may be related to the West?s development of a neo-liberal concept of governance.

This paper presents a study of the computer game ?Minesweeper?. The aim of the game is to search through a rectangular area of mined squares without hitting any mines. 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.

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.

Unlike previous research, this thesis considers the possibility of regarding the morning prayers in Swedish schools as preaching, rather than teaching. 28 morning prayers, delivered in the church of S:t Johannes in the city of Malmö during 1939-1954 by the religious teacher Astri Heimer (1889-1986), constitutes the material for analysis. The purpose of this thesis is to examine if Heimer's morning prayers may be regarded as preaching, and to discuss the significance of this, in particular considering her role as leader of morning prayers.The examination is conducted in three steps. The first step investigates how morning prayers in general ought to be understood - as teaching or preaching? This is done by describing and comparing the literary genres of religious teaching and preaching, looking into the rules and principles which define the field of application.

In this essay I have described ecocriticism as a theory with several different subfields that are inspired by a cross-disciplinary approach, such as green culture studies, ecofeminism, and postcolonial ecocriticism. After a short summary of the background of ecocritical studies I analyze the various subfields, take a closer look at their contents and present various examples of ecocritical thinking. A presentation of the commonly used concepts within the discipline and some reflections on these is followed by my final discussion, where I state that even though ecocriticism is a relatively new theory and the concept doesn?t have a clear definition as yet, it is in my view a useful tool for analysis and can with time make valuable contributions to literary studies, not least by introducing a number of new perspectives..

In my study I have chosen to examine the mathematics in children's free play and everyday situations, with focus on sorting and classification. The purpose of the study was to see how children express their mathematical knowledge. I have chosen to use a qualitative method in my examination, here I did observations in a children's group where the children were between three and six years old. I also did interviews with the teacher's on the department to see how they relate to the mathematics and how they formulate the department to achieve as good a learning environment as possible.The result shows that the teacher's approach is incredible important to the children's learning ability and that they are always present to challenge and discuss together with the children. The observation indicates that children use mathematics all the time in their everyday situations and that it is the interaction between individuals and environment that affects children's development. .

Bacteria are exposed to evolutionary pressure to an extent unlike other organisms. This leads to a high degree of adaptation to its surrounding. This thesis investigates the degree of adaptation towards higher accuracy in the transcription of DNA to RNA in coding sequences in the DNA of the E. coli bacteria. Two coding sequences with different nucleotide contents were investigated.

We where asked to write a webapplication, with similar functionalityas an existing desktop application. The application can todayrecord sounds from a person, mix it together at the optimal place withanother, similar sound and play back the result.The application used mathematical calculation that the developerswhere not familiar with, therefore it was decided to focus on the partsthat involved recording and playing sound, to pave the way for anyfuture implementation.The follwing prototypes where implemneted:1. Read a sound clip from a file.2. Splicing of two sound clips at different points in the clips.3. Generate the sound of a guitar.The result of this evaluation is that web browsers today are notready for this type of application, but that there is potetial as soonas W3C have standardised the use of a microphone as a source to theexisting DSP functions..

Matematikämnet och elevers bristande kunskaper i ämnet, har starkt uppmärksammats senaste åren. Vi har konstruerat ett matematikspel i syfte att införa ett arbetssätt i undervisningen, som bygger på pedagogiska faktorer såsom kommunikation, reflektion, social aktivitet och motivation. Målgruppen har främst varit förstaårselever vid gymnasiet. I denna undersökning har såväl elever som lärare och andra pedagoger deltagit i syfte att värdera spelets funktioner som en del av undervisningen. Det centrala har varit hur och om spelet kan stimulera elevers motivation och kommunikation i positiv riktning för att på så sätt skapa förutsättningar för ett bättre lärande.
