The aim with this study is to illustrate the underlying causes of students? difficulties in Mathematics from a teacher perspective. The approach that has been used through this study is qualitative, method wise interviews were used. The selection for the study consists of five teachers with many years? experience in the subject of Mathematics.

Agriculture has to be performed in a sustainable way in order to sustain high yields and to support a globally growing population. Functional soil properties are fundamental for high yields and in order to achieve good soil conditions sustainable management is a key. Loss of soil organic material and increased soil acidity are problems associated with degradation of soils and hence less sustainable agriculture. In this thesis, the effect of different agricultural systems on soil organic matter, pH and yield was examined. The systems examined are a cereal system with straw removal or returning and a ley system, all with different nitrogen levels.

The aim of this report is to improve the fire safety at Hallsta Paper Mill in Hallstavik, Sweden. In order to do so large parts of a fire-protection management system for the paper mill has been created. The report begins with giving a general description of management structures and fire-protection management systems. An account is given for how management structures are designed, and how they should be implemented, maintained and updated. Thereafter follows a description of what routines and instructions should be included in a fire-protection management system..

ABB Capacitors Ludvika started their LEAN-project in november 2010, but still has not the whole factory been introduced to the LEAN-tool called 5S. 5S is only implemented on the ?easiest? work-areas.By implementing 5S, at the workingstation called inburkningen, would make the workstation and the area around it much more structured, clean and systematized. The operators are a little bit skeptical to the work that includes continuous improvement today, because they can not see any progresses. If 5S were implememted the operators would be able to avoid searching for tools because with 5S, each tool will have a specified place at the workstation.5S would simplify the cooperation between the shifts, because 5S includes clear instructions for how the workstations will be cleaned after each shift.This report will include my recommendations, thoughts and opinions regarding however ABB Capacitors Ludvika should implement or not implement the LEAN-tool 5S.

The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

Recently I discovered that preschool education has evolved from integration of various subject contents and working methods. The purpose of my study is to investigate preschool teachers' attitudes and ways of working with a theme-oriented approach. I also want to examine their opinions regarding the integration of subject content in terms of mathematics and science subjects (NO) in preschools theme-oriented work approach.My questions for this study are:What is a preschool teacher's attitude and their ways of working to a thematic-oriented approach?What is a preschool teacher's opinions regarding the integration of subject content, especially in mathematics and science subjects (NO) in their pre-schools theme-oriented work approach?I have used myself a qualitative method of investigation to produce materials for my research project. I collected my empirical material for my study from the semi-structured interviews that was done with four preschool teachers in two preschools in Botkyrka municipality.

This paper is a study of some of the mathematics textbooks that were used in Swedish public schools from 1842 to the present. During this period several revisions of the curriculum took place and led to a change of contents in the various books. The first part is a description of the books chosen and highlights from each are given and compared with the corresponding curriculum. Also social and political change and the role of men and women can be studied in the examples presented. A comparison between similar topics and how they were accounted for in the older versus the newer books follows suite.

The project group is participating in a measuring project that is a cooperation between CIT EnergyManagement AB, the Measuring unit of Chalmers and College of Dalarna.The results from the measurementswill be put together and presented in a brochure.When designing the brochure a great deal of planning has been made how to attract the targetgroup.To make the contents of the brochure more attractive, which mainly will contain text, a lot of imageswith a symbolic substance have been used. To keep the brochure together it has been divided into fivechapters that each has been given one specific colour. The colours are consistent on initials, headlinesand images.At the moment the results of the measurements are not yet ready and the text for the brochure is notpossible to complete now. This project is expected to finish in the fall when all the measurements havebeen compiled..

The aim of this paper is to analyze how syllabus plans for the course Swedish for immigrants have changed in the past 40 years. The paper focuses mainly on how different theories on learning in general and second language acquisition in particular have influenced the syllabus. Furthermore, the paper attempts to identify changes in how the teachers? role is described in the documents. My results indicate that syllabus plans from the 70?s were influenced by behaviorism, progressivism and the sociocultural view on learning, while syllabus plans from the 90?s and 00?s show only influences from the two latter perspectives.

Before the European construction standards were introduced in January 2011, it was mainly themethod in BBK04 that was used for calculating punching capacity in concrete structures, and in lesscommon cases the method in BHB. The method of BBK04 is easy to use and have had the samestructure since the first was published in 1979. The Concrete handbook method (BHB) where usuallyonly used when a higher punching capacity was needed and the cross-sectional height where fixed,calculations using this method entails more work, but will in return usually give a higher capacity. Italso allows the use of shear reinforcement to increase the cross-section capacity. The method ofcalculating punching shear in EC2 differs largely from the methods of BBK04 and BHB.

The thesis first objective was to develop field instructions for forest planning of native forests in Andean Patagonia, and the second objective was to test the plan on an actual property in the area. The thesis was limited to studies in the province of Rio Negro. Today, there are no official forest management plans for native forests in the Argentinean province of Rio Negro; thus, there is an obvious need for an official forest management plan with clear guidelines. To be granted permission to manage, i.e. through thinning, the native forests on a property it is required to have a forest management plan that is approved by the Forestry Board in the province in question (Thill, B.

Many people turn to documentaries for knowledge about animals, but do documentaries give us a truthful portrayal of animals and their behavior? This study looks at how the communication behavior of the portrayed animals is depicted in three episodes of The Life of Mammals. These episodes were observed after which the contents were compared to scientific literature on the same topics. The results show that quite little communication is actually shown in the episodes about plant predators and meat eaters and relatively much of it is shown in the episode named Social Climbers, involving primates. The matching literature suggests that based on the narrative and the accompanying footage, the viewer is getting a realistic picture, with the exception of a few questionable cases..

In 2010 there will be a political resolution to ensure that the Swedish society is accessible to all citizens including people with disabilities. For this purpose a national action plan for disability policy "From patient to citizen" (Govt. Bill 1999/2000:79) has been set out with the aim of ensuring that the disability perspective will permeate every sector of society and that the approach and response to people with disabilities will be improved. The Swedish National Council for Cultural Affairs is responsible for implementing the disability policy in the cultural sector.Since public libraries in Sweden are a part of the public cultural sector, they will also be affected by the political resolution regarding accessibility. The concept underpinning library services for disabled people must be that of equality of access.

In this thesis, the four types of math problems that occur in the digital educational math game Zcooly Affären 2 have been analyzed. Focus has been aimed at how the problems mediate instructions and mathematical concepts to players, and how the mathematical content is supported by the context within the game. The result shows both positive and negative aspects of the math problems, based on the theories for math education used in this thesis. Apart from the analysis of the game, this thesis also presents earlier research regarding what possibilities digital games possess as tools for learning. Researchers have partly different views on how digital games should be designed to enhance learning, and whether or not games are efficient to use for learning purposes..

In many earlier investigations a recall advantage of auditory lists spoken in a single voice has been found over recall of lists spoken in two alternating voices. One explanation proposed is an organization strategy which makes recall of alternating-voice lists so difficult. The strategy implies sorting same-voice words into same-voice groups at encoding. Based on this proposition, it was assumed that voice-by-voice recall would be better than recall in order of presentation, as then the recall instruction and the organization of items in memory would be in concordance. The present experiment tested and was unable to support this hypothesis.
