Måste vi ha NO? : Elevers uppfattning om sin NO-undervisning i skolan

During my education I have frequently noticed that pupils do not like science or find it hard and dull. The purpose with this investigation is to find out how pupils experience their science education and if they can understand the arguments for studying the subject at school.I have made a questionnaire study among pupils in grade 8 and 9. After analyzing their answers I have interviewed some of the pupils to get answers on further questions.The investigation resulted in conclusion that pupils have hard to connect their science-education to their everyday lives. The most important element in forming the pupil?s opinions about science is their relation to the teacher and how the lessons are set-up.The following questions will be answered in this paper:Do pupils understand why they have science at school?Can the pupils see the use of scientific knowledge in their everyday life?How do pupils look upon their science education?.

Thomas Kuhn och paradigmteorin idag : Från normal till postnormal vetenskap

This essay describes the philosophy of science that Thomas Kuhn puts forth in his work The Structure of Scientific Revolutions. The question is, does his description of the scientific paradigm work as well today as in the examples he gave in the book?The conclusion is that there are certain factors that make for a number of differences between science today and, for example in the seventeenth century. There is also a growing theory or vision of a post normal science laid developed by among others Jerome Ravetz. This theory or vision is an idea of a science close to peer-communities and fast as well as critical decisions involving opposite values..

Barns föreställningar om de första djuren som utvecklades på jorden

No previous studies have been conducted on elementary school in Sweden about children`s thoughts about the first animals on earth. The work takes up the children`s ideas of the first animals and the difference between girls and boys knowledge. The purpose of this work was to determine if student`s views are consistent with the science know today. In the interview, five girls and five boys participated. Mankind is asking where it all began, today we know that the first life arose for 4 billion years ago and it was from the water.

Skrylleområdet - naturupplevelse som motivation till motion? :

Our lives in urban areas are becoming more and more inactive with negative effects on our mental and physical health. Natural environments and physical activity have the power to both prevent and reduce mental fatigue. Meanwhile we engage ourselves with physical activity, the nature fascinates us with its complexity. In April 2006, some of the visitors to the recreational area of Skrylle were asked to fill in a questionnaire which included questions about their habits within physical activity and the experience of nature. The questionnaires were then divided into two groups: those filled out by persons who exercise on regular basis (i.e. three or several times/week) and those who rarely exercise.

Naturlig nedbrytning av klorerade lösningsmedel i grundvatten

Chlorinated solvents are common contaminants in soil and water. Under anaerobic conditions microbes are capable of transforming chlorinated solvents into ethylene which would result in a remediation of the contaminated area. In order to use natural attenuation as a remediation method evidence of continuous degradation is required. Furthermore, the degradation must occur at a sufficient rate and continuous monitoring of the site is needed until the demanded levels are achieved. A field study was performed on the basis of data from a dry-cleaning facility contaminated mainly by perchloroethylene.

Androidvetenskapen och den kusliga dalen: Japanska robotar som forskningsplattformar och filosofiska leksaker

The primary aim of this essay is to analyse, contextualise and problematise the scientific and technological goals of android science. The starting point of this investigation is the history of automata and man?s attempts to recreate himself by technological means. Drawing on the no-tion of boundary work this essay also analyses the efforts of the proponents of android science to establish and demarcate a new interdisciplinary field. A secondary aim of the essay is to evaluate the scientific support for the uncanny valley hypothesis and to investigate how this hypothesis contributes to android science.

Förlorad i övergången från aritmetik till algebra : Hur gymnasieelever översätter aritmetik till algebra

The aim of this thesis is to look for signs of students? understanding of algebra by studying how they make the transition from arithmetic to algebra. Students in an Upper Secondary class on the Natural science program and Science and Technology program were given a questionnaire with a number of algebraic problems of different levels of difficulty. Especially important for the study was that students leave comments and explanations of how they solved the problems. According to earlier research, transitions are the most critical steps in problem solving.

Humanioran och Open Access ? en kvalitativ studie i drivkrafter och strategier hos litteraturvetare inför publicering

The Natural sciences and the humanities are associated with differentpublishing patterns. Open Access publishing are mainly associated withthe publishing patterns of the Natural sciences. Many Swedishuniversities and research funders are proponents of Open Accesspublishing, what will that trend mean to the scholars with a publishingpattern not corresponding to Open Access? In this paper literary scholarsare interviewed for the purpose of learning the motives and strategieswhich form their publishing pattern, and how they relate to Open Accesspublishing. The results show that literary scholars are less competitiveand hold a more gentle knowledge-sharing ideal, than natural scientists.The drive to gain acknowledgment and the recognition of colleagues inorder to collect academic capital as Bourdieu describes the academicfield is still present though.

Förbättring av upplösningen i Landsat 7-bilder med hjälp av bildfusion

The purpose of this master's thesis is to evaluate whether it is feasible to use the panchromatic band of Landsat 7 in order to improve the spatial resolution of colour images. The images are to be used as texture in visual databases for flight simulators and for this reason it is important that the fusion preserves natural colours.A number of methods for fusing panchromatic and multispectral images are discussed. Four of them are implemented and evaluated. The result is that standard methods such as HSI substitution are not suitable for this purpose since they do not preserve natural colours. However, if only high frequencies of the panchromatic image are used the resolution can be improved without noticeable colour distortion..

Den kommunicerande forskaren : Forskares tankar kring och arbete med forskningskommunikation

As the western society gradually turns into a knowledge- and risk society, where science and scientific innovations increasingly both promise to save the world and destroy it, a shift in the relation between the scientific community and the rest of society has emerged. A shift from a top-down one-way transfer view regarding communication, to a dialogue-based interactive co-production model, where the public are part of setting the agenda for research and contribute to the knowledge production. Or at least in theory, in EU documents and in many different country's policy documents. In practical application however, one might have a hard time see the implementation of such model.As a more comprehensive and dialogue-based science communication is depending on the possibility for scientist themselves to engage and fell the need to engage, we have focused on their thoughts.In this thesis we have examined six scientists view on, and work with, science communication, as well as their perceived social and structural conditions. We have also examined action plans and strategy documents from three Swedish universities that in different ways mention science communication and interaction with the broader society.

Naturvetenskap i förskolan : En intervjustudie om förskollärares tankar och arbetssätt

The aim of this study was to investigate how preschool teachers think about preschoolscience, what they consider science to be and how they deal with specific curricular objectivesrelated to science.Science is a part of our everyday life, it is a prerequisite for understanding everydayphenomena and how the world is working. Nevertheless it is often dropped in favour of othersubjects in Swedish preschools.The eight preschool teachers participating in this study are all working in the samemunicipality in the western part of Sweden with children aged 1- 5 years. The method used inthis study was interviews. The interviews were recorded to facilitate the transcriptions.The results show that preschool teachers find that science is an important subject that shouldbe introduced to the children early on in life. They also show that preschool teachers considerscience to have a preventive effect on the learning to the children, and it is needed for them tounderstand everyday processes and phenomena.

Natur på skolgård : värdet av naturlika miljöer och deras utformning för barn

As a result of my fascination for nature I have chosen to study the possibilities to introduce natural environments on schoolyards. Too many schoolyards are lacking vegetation and many of them look like sterile asphalt deserts. The master thesis consists of two parts. The first part is based on literature studies and the second part in which findings from part one are put into practice. Five examples are presented; four schoolyards in Malmö; Kryddgårdsskolan, Kirsebergsskolan, Rörsjöskolan and Lindängeskolan and one in Kalmar; Åbyskolan. Malmö Naturskola has been working with the chosen areas on the schoolyards in Malmö.

Tätortsnära skogsbruksplan i Borås stad

This report is part of an Bachelor of Science work in forestry, conducted for the community of Borås, Sweden. In order to create a forest management plan for the area of Hestra, a survey was conducted. People living in the area were given the opportunity to reply to the survey. The questions in the survey are both personal and forestry-related. The aim is to reach out to the different categories of people when it comes to age, living and the different aspects of visiting the woods.

Trafikklasser för markplattor av natursten : förslag till klassificeringstabell

This report deals with hard surfaces and the factors which are behind the criteria for dimensioning, also dependent on the level, or volume, of traffic. A test was made on slabs of two kinds of natural stone. This was made to see if the values that were reached for breakload was transferable to the same tables that the concrete industry is using for surface dimensions of slabs and paving stones. The test showed very high values and the result, together with the written study, led to the author?s suggestion for a classification table where slabs of natural stone were divided in to different classes depending on traffic, thickness and durability..

På färd genom glömda landskap : Rumslig analys av bronsåldersbygden i Mönsterås

This paper deals with the relations between landscape rooms and monuments in an area north of Mönsterås in Kalmar län. After archaeological excavations had been carried out in the area 1991, an article promote it to the ?Bronze Age district of Mönsterås? (Källström 1993). There are two main problems that I deal with in this paper. First: The relations between the natural places and the monuments or memorials.
