Att skapa förutsättningar för lärande på science center
Uppdraget som låg till grund för detta examensarbete var att utveckla Vattenfall Science Centers utställning och verksamhet. Uppdraget formulerades i ett syfte att studera hur sciencecentret som koncept kan utvecklas genom att pröva hur ett sociokulturellt perspektiv pålärande yttrar sig i skapandet av en interaktiv installation. Målet med arbetet är att föreslå hurett science center kan formas och utvecklas för att skapa förutsättningar för lärande.Arbetet delades upp i tre delar. Första delen består av en studie av litteratur med syfteatt få en övergripande bild av den forskning som berör lärande på museer. Målet var att belysaviktiga aspekter för lärande på museer.
"I will go now to my pyre" : Isaks bindande läst genom J.R.R. Tolkiens The Lord of the Rings
This paper investigates the science fiction novels of Swedish crime writer Per Wahlöö, most famous for his collaboration with his writing partner Maj Sjöwall on the ten Martin Beck mysteries. During two important years, 1964 and 1968, Wahlöö wrote the novels Murder On the 31st Floor and The Steel Spring, set in a near future land ruled by a social fascist power structure where political opposition is eradicated. The pretexted notion of this paper is that these novels consists of extensive quantities of criticism against the Swedish welfare state and the monopoly-capitalistic Swedish press during the sixties. Through the lens of science fiction theory and the notion of the novels as historical sources this paper concludes that PerWahlöö´s science fiction becomes a bridge between the classic Swedish detective novel and the new social critic crime fiction in the style of Sjöwall-Wahlöö and others. The novels are also representations of the historical process in the mid-sixties during the radical turn: the sci-fi novels as social criticism of the contemporary society ? an utopian flare.
Interaktion i klassrummet
I den här rapporten beskrivs hur elever mellan åtta och tolv år upplever
användningen av datorn och Internet i skolan. Genom att studera användningen av
Internet med hjälp av intervjuer, deltagande observationer och informella
samtal har författaren i den här rapporten valt att utifrån elevernas
perspektiv beskriva deras situation. Utifrån den etnografiska studie och de
konstruktionistiska teorier författaren gjort utnyttjas sedan erfarenheter från
utbildningstiden för att försökta skapa ett koncept om hur ett framtida
klassrum skulle kunna komma att se ut.
Undersökningar har gjorts om hur information, kunskaper och erfarenheter utbyts
i klassrummet och vilken betydelse det har för användningen av Internet. Men
även hur elevernas själva utvecklas och skapar sig ett kritiskt tänkande och
att lära sig sortera, för dem, relevant information. Jag har även studerat hur
lärarens roll förändras och hur det påverkar undervisningskulturen.
Att Synliggöra det Osynliga : GIS som verktyg i sökandet efter bosättningsområden från bronsåldern på Gotland
In this bachelor essay an attempt is done, to recreate a probable Bronze Age landscape on Gotland, with GIS as a tool. The landscape on Gotland is situated with many different monuments dated Bronze Age, such as cairns and stone ships. In creating of the maps, two possible shorelines contemporary with the Bronze Age have been calculated and marked on the maps. Furthermore, peat lands have been drawn upon the maps, by using the information from geological maps.A landscape variable have been compared between Bronze Age places and Early Iron Age houses; the soil type. On Bronze Age places gravel is the most common, while moraine marl is the most common on places with Early Iron Age houses.From a selection that were made, all Bronze Age places where within 3 km from the water, either the recreated shoreline or peat land.
Det finns 10 sorters människor - de som förstår och de som inte förstår. : Lärares uppfattningar om matematik och matematiksvårigheter.
This report is an attempt to clarify how religious and non-religious views-of-life [livsåskådningar] are created through the collaboration and opposition of religious and scientific elements/ideas. This with the hope of reaching a fruitful result related to the solution of world-view related conflicts, such as the ones existing between science and religion, on an individual and societal level.This is accomplished with the help of two assertions: (1) Mankind has a need to explain its existence and surroundings. (2) Religion and science has their origins in the same seed and aim to serve the same purpose, or function. Together these two assertions lay the theoretical foundations of this report which implies that all humans have an innate need of sustaining a stable world-view.The result of this report is that a final solution to world-view related conflicts are beyond reach as our mental and physical nature limits us. However there are strategies for minimizing world-view related conflicts effect on society..
Jämförelseförsök mellan ogräsharvning och radhackning :
The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010.
The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing.
In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment.
The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment.
Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..

Fyra uppdrag om människokroppen för grundskolans senare år
Recent studies show that the knowledge in and understanding of science, technology andmathematics of Swedish junior high school and high school students is decreasing. As a resultof this the Swedish government has initialized several studies, research and reforms. One ofthe theories for teaching that today is seen as effective is the socio-cultural perspective and itsdescendants, including scientific inquiry. Using the pedagogy of the socio-cultural perspectivefour assignments regarding the human body was constructed for junior high school studentsattending summer research school in the summer of 2008, hosted by AstraZeneca. Theassignments follow a structure (goal of assignment, preparations, experiment and follow-up)inspired by the concept of NTA ? Naturvetenskap och Teknik för Alla (Science andTechnology for everyone).
Ungdomar om bibliotek
The aim of the thesis is to study young peoples, defined as boys and girls between 14 and 16 years old, attitudes to library in two municipalities. Notwithstanding the fact that young people, and children, often is given priority in library work, the reality often seems to be another. Attitudes are founded primarily in childhood and therefore it is of great importance to examine how young people regard libraries. Besides studying former research about young people and libraries that has been performed on library and information science, we also have been using concepts and theories from social science. We give a brief outline of youth research and its development and look at official records and legislation to see if and in what context young people are mentioned.

Kålgallmygga, Contarinia nasturtii Kieffer : en växtskadegörare på kål
The purpose of this paper is to examine what problems cabbage growers have with the
Swede Midge. The last few years the Swede Midge, Contarinia nasturtii, has become
a larger problem for cabbage growers in several countries in Europe as well as in
Sweden. In Canada the problems are so severe that the midge is classified as a
quarantine pest and therefore certain rules have to be followed. I have collected facts
of the biology, host plants and reproduction of the Swede Midge, as well as the
growers experiences and the occurrence of the midge in Canada, Europe and Sweden.
The Swede Midge is hard to control because of its short life cycle and the larvae are
protected between the heartleaves of the plant. When the larva feeds on the growth
point the plant becomes distorted, in some cases several heads develop or none at all.
When the midge infests spring rape its flower buds become undeveloped and rosette
like.
