Räkna med läsning : En undersökning bland elever i årskurs nio om samband mellan läsförståelse och matematisk problemlösningsförmåga
Swedish students' knowledge of both mathematics and reading comprehension has deteriorated in recent years. Scientists are discussing whether there is a connection between these areas and that the pupils deteriorating math skills may have something to do with their increasingly lower results in terms of reading comprehension. To investigate this possible connection, I conducted a survey among students in ninth grade and have come to the conclusion that the scientists are right: this connection absolutely exist. Students who received a high score on tasks designed to test students' mathematical problem-solving skills, also received high results on the reading comprehension test. And students who received a poor performance on the problem-solving tasks, were also low performers in the reading comprehension test.
Serbiens symboler : en fördjupning och bearbetning av den traditionella folkdräkten och dess symboler i kontrast till serbiska kvinnan idag
I have always been told that form follows function. But does it have to be that way? I decided to see it from another angle.Kinesics is a term form non verbal komunication. In my thesis project I have been working with body language in furniture. I believe that furniture, just like us, has an expression and a character. We often tend to desccribe furniture with the same words as we describe people, for example: "A relaxed chair" or "a cocky table".
"Jag skulle vilja köpa 1 öra och 1 par lungor" : En innehållsanalys av uppgifterna i ett digitalt pedagogiskt matematikspel.
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..
Mode & identitet : - Att visa sin insida med utsidan
AbstractAim: The purpose of this thesis is to research how women think about fashion in relation to their self and to others. Can clothes be an expression of who we are who we want to be and how we look at others? What are the main characteristics in this type of communication and what kind of information can be distributed using this tool?Method/Material: InterviewsMain results: Clothes can work as a tool to show who we are and what we are, mainly on short term. We use clothes for different purposes, sometimes we what to be seen and really show who we are and what we stand for and sometimes we just what to go with the flow and not be seen at all. We will always have a physical need for clothes but it is also a natural and important part of our individual expression and our identity.Keywords: Fashion, Clothes, Identity, Lifestyle.
Registrering och avel för brunstvisningsförmåga hos mjölkkor
Dairy farmers using artificial insemination (AI) are dependent on effective oestrus detection. In Sweden, AI is used for a majority of all dairy cows and oestrus synchronisation with hormones is not allowed. There are reports of declining ability to express oestrus with higher levels of milk production. This makes oestrus detection more difficult. Several aids for oestrus detection have been developed, for instance pedometers and mounting detectors.
Modellering och simulering av hovrande helikopter
At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.

Gene expression from a cold-treated Swedish isolate of Haemonchus contortus
Totally 84 differentially expressed mRNA clones from infective L3 larvae of the parasite Haemonchus contortus, a blood sucking nematode, were analyzed with single strand hybridization assay (SSH). Altogether 79 clones were sequenced, edited, and compared with proteins found via BLAST in GeneBank. The aim was to investigate gene expression and potential protein expression following storage at 5 °C for 32 weeks. mRNA was extracted from fresh and stored L3. The SSH derived products were cloned into E.
ATT GÖRA EN FIN DAM HETERONORMEN I EN FÖRVANDLINGSKOMEDI
Analysis of the piece Pygmalion in set at the Gothenburg City Theatrefrom a gender perspective with the purpose to investigate which genders that arepresented and how the piece relates to the heterosexual norm. The method consists inthe analysis and discussion of how the pieces portrays females and males (with focuson feminine and masculine coded expression and presentation of desire) and whatconsequences it brings. This based on various method books of norm-breaking designwork for Aesthetic staff, and a theory based on Judith Butler's research. Primarymaterial consists in a piece analysis of Pygmalion, from a spectator's perspective.Main Results: The designing is consciously working with a set of norm-breakinggender expression, particularly female genders. The set translates socially criticalviews against patriarchal hierarchies.
?-galaktosidas assay för studie av promotorregion i kloritdismutas från Ideonella dechloratans
Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. There are two different kinds of bacteria that can use oxochlorates as electron acceptors in their metabolism, bacteria that break down perchlorate and bacteria that break down both perchlorate and chlorate. A bacterium that can break down chlorate under anaerobic conditions is Ideonella dechloratans which holds the genes for chlorite dismutase and chlorate reductase which are enzymes for the degradation of chlorate. Gene expression and enzyme activity of chlorite dismutase are induced under anaerobic conditions, which makes it interesting to find out how this regulation functions in order to better exploit these bacteria in biological wastewater treatment.
Numerisk värdering av amerikanska optioner
The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.
Utveckling av dynamiska farthinder
The aim of this Master of Science Thesis is to develop guidelines and improvementsuggestions of RiNOVA Traffic AB?s dynamic speed bump. The project started with athorough pre study of the design and its function to find out how passing vehiclesaffects the dynamic speed bump. The majority part of the pre study was to createnecessary mathematical models to explain the arisen forces and strains.The results of the mathematical models gave necessary information about the designregarding weaknesses and flaws. The most critical ones where those which interferedwith the design?s performance and reliability, and therefore needed to be corrected.These problems where more thorough analysed and discussed with experts before thefinal guidelines and improvement suggestions where developed.The parts of the design that had to be redesigned were the extension springs and thebearing that enables the dynamic properties.
Att tala så det träffar : Om konsten att ge och ta feedback
To have a functioning organization where there is a self-development for employees them selves, as well as between managers and employees, where employees are empowered and work for the organization and its goals. Feedback seems to be the main instrument to solve problems and create that organization. At the Military Academy Karlberg and the basic officers training there is a lot of discussions about feedback and how it is supposed to be carried out. This essay discusses the matter of how well we live up to the demands set by leadership classes at the Military Academy, what the platoon leaders do think about how feedback takes its expression. The questions about how feedback is used are to be answered by interviews with five platoon leaders and their thoughts about how feedback is communicated at the Academy.
Lärarens syn kring elevers motivation till matematiken
This survey is a case study with the purpose to find out the teacher´s perceptions about students´ motivation to mathematics. Further this study aims for the teacher´s vision on how they consider students´ motivation in mathematics in secondary school. To collect research data I have used semi structured interviews with four secondary school teachers. The result constructs according to categories that depict the purpose of the study. These categories define students? motivation like achieving different goals, students? basic knowledge, abilities and perceptions of mathematics and external factors that affect students? motivation.
