Gymnasieelevers förståelse av enhetscirkeln och trigonometri : en undersökning av elevers förståelse av matematiska begrepp, samt vad lärarna anser att nyblivna matematikstudenter bör kunna när de kommer till högskola eller universitet
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.
Innovativ utmatningsteknik : Mediumstor bulkförvaringslösning
This master thesis was done for a company called BRUKS which is active in woodprocessing,bio-energy and bulk material handling industry. The idea for the master thesis wasto develop a new reclaiming method for silos where wood chips are being stored. A mediumsegment of between 1000 ? 5000 m3was defined as the segment with the most sales potential.Two different concepts were produced, one for new constructions and one for rebuildingalready existing silos.In the beginning of the master thesis a lot of time was spent on visiting different BRUKSoffices and customers to get an overview of the industry and the product. This informationwas the basis when the idea generating phase began.
Smart plombering och märkning
The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.
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.
Att folkomrösta eller icke folkomrösta? : En analys av debatten om huruvida EU: s grundlag bör antas genom en folkomröstning eller ej
The primary purpose of this thesis is to study how political agents construct and give meaning to the concepts of democracy, representative democracy and referendums. The starting point of the thesis is the pressing issue whether or not Sweden should hold a referendum on the new EU constitution. To analyze this question my choice of method is critical discourse analysis and the topical theories revolve around democracy and responsibility.My study shows that there are three different discourses in this debate: ?the democratic process?, ?the representative democracy? and ?the concept of democracy?. However, the meaning of the concepts in these discourses varies depending on which side the political agents are on.

Livslångt lärande och folkbibliotek
The purpose of this master thesis is to investigate and analyse how the concept of lifelong learning is expressed in political documents concerning public libraries and education and how it can be related to earlier concepts of education within the discourse of public libraries. Focus is the official approach to the concept of lifelong learning and public library. The documents examined contain the political aims for education and culture policy on a national and local level. The theories used in the study concern the background and meaning of the concept of lifelong learning, they describe public libraries and their earlier perspectives of education and they also give a picture of practices of governing within the framework of public libraries. The purpose is to see how the speech in the documents is reflected in discourses of society and public library.
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.

Grov vårdslöshet : om friskrivningens yttersta gräns på det materiella tjänsteområdet
Our purpose with this research is to highlight that there is a scope for increased value creation in the experience room during concerts, and how value-enhancing strategies can be a competitive advantage for different venues. In our investigation of this we have worded the following research question: How is the perceived customer value affected during a concert in the experience room and its physical environment? With the background in this question we have identified three key concepts that we believe are the influence of the total concert experience which are; sensory experiences, interaction and identity. From these concepts we have drafted a number of propositions to test the reality by our empirical data collection. .
Hur lärare arbetar med barns läs ? och skrivinlärning
AbstractThere is a lot of confusion when it comes to defining Special Education. An example of this appears here by a statement from Assarson (2007) "Special Education initiates a special pedagogy, but contains no innate sense of what is the special component in it" (p. 52, authors? translation). This study is an attempt to clarify the elements of the concept.
Ledarskap i Globala Virtuella Projekt
Language is an important indicator of the interdisciplinarity of a certain subject. Therefore this study evaluates the use of central geographical words and concepts, by teachers and students, in seven communal, non-optional subjects in a Swedish upper secondary school. This study provides results after observations of seven subjects on seven occasions, at one upper secondary school. This study shows that by a method of observation, central geographical concepts were used by teachers and students at various extents. Furthermore, the observations provide results of the concept use by over 100 students and 12 teachers.
