Digital elevdokumentation : från implementation till praktiskt arbete

It is statutory that teachers shall document their student's development of knowledge in different subjects. The teachers employed by Sundbybergs municipality have been commissioned to do the documentation in the web-based electronic system Projekt- och Omdömesdatabasen, P.O.D.B. The purpose of this study was to investigate witch effect the IT-solution P.O.D.B has brought for the teachers in their task of student documentation. By conducting interviews and questionnaire studies I have been looking for answers to if the target achievements have increased by using the IT-solution, and if the teachers are aware of what they may or may not write about their students in the system. The conclusions I have been able to draw through my studies are that the teachers have accepted the commission to use P.O.D.B.

IT- och mediefortbildning i gymnasieskolan

Syftet med denna studie var att undersöka attityderna gentemot PIM hos ett fåtal praktiserande gymnasiepedagoger. Jag ville även undersöka om PIM upplevs i samma positiva riktning som Skolverket anger i sin lägesrapport från 2009. Syftet är också att med fokus på gymnasielärare utreda hur innehållet i PIM-satsningen upplevs, huruvida ambitionen med satsningen införlivas efter deltagande och om dessa pedagogers undervisning och didaktik påverkas av att genomföra PIM. Uppsatsens huvudsakliga frågeställning är: Upplever gymnasiepedagoger i Malmö att deras medverkan i PIM bidrar till högre undervisningskvalitet? För att samla in information till studien genomförde jag kvalitativa djupintervjuer med sex gymnasielärare. Den genomförda studien är väsentligt mindre vad gäller informanternas omfattning i jämförelse med skolverkets lägesrapport.

Konstruktion av steghållare till brandbilar

High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.

Konstruktion och utvärdering av diplexer

The report descripbs how a diplexer for a hybrid analog/digital filterbank has been constructed and tested. A diplexer divides the frequency band into two different bands that do not who doesn't overlapp each other. The sampling rate for the two ADC:s is 80 Msps, and therefore it is advantage to have zero at 80 MHz. The reason for this is that a proposed class of hybrid filterbanks with very good quality requires a zero at or close the sampling frequency to work well. The diplexer was made in three versions.

Styrsystem : För en forskningsutrustning

The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.

Omkonstruktion av armled tillhörande Bracke Forest högläggare

One of the main tasks of the Swedish Armed Forces over the past few years has been International assignments, which increased the importance of the Lessons Learned process. Methods of simulator training with computers have become more frequent and the technical ability to collect digital data from sensors has been developed as well. This work demonstrates how the experience of Lessons Learned can be communicated with the computer simulator StriSimPC and how modern technology in future support experiences from the Lessons Learned process at the tactical level in the Army.Currently knowledge sharing consists of several processes and strategies in the Swedish Armed Forces. This is done by written reports, oral presentations and different practical exercises.This case study shows the functions of the simulator StriSimPC, methods of training and how it is used today. The study also describes the future opportunities, where digital metadata acquired from the modern combat vehicles could contribute sharing of experience in the Lessons Learned process.The summarized conclusions indicate that StriSimPC can combine the two strategies for personalization and codification of knowledge transfer to reach a higher level of learning.

IKT i undervisningen som motivationshöjare

Syftet med examensarbetet är att undersöka om användningen av digital teknik i undervisningen har en positiv effekt på elevers motivation, vilka för- och nackdelar undervisningen med IKT kan ha med hänsyn till inlärningens effektivitet och om pedagogens roll i klassrummet förändras när digitala medier används. Jag har upprättat en kunskapsöversikt med relevant litteratur för att belysa undersökningens frågeställningar. Undersökningen av litteraturen har visat att digital teknik kan ha en positiv inverkan på elevernas motivation, men att det ofta är den yttre motivationen som gynnas, och inte den inre som ger en större inlärningseffekt. Arbetet med IKT i undervisningen har många fördelar, bl.a. är möjligheten att arbeta med olika sinnen stor och att det gynnar olika inlärningstyper.

The task has been to develop a holdingsolution that generates force between two rolls and to evaluate the new solution withrespect to functionality, manufacturing, structural stability, costs, assembly etc. Theroll holding solution is a system that is part of a rollpress. The rollpress is used towash and dewater pulp. The existing solution creates forces that have to be absorbedby the gable of the press.

Extra! Extra! En studie i urval och nyhetsvärdering av push-notiser

This case study aims to find out whether the promotion of Swedish news through push technology, and the selection process behind it, obeys the traditional criteria of news values.A months-worth of push notifications, sent out by the mobile phone applications of newspapers Dagens Nyheter and Expressen, were analysed through the application of a number of taxonomies meant to determine their newsworthiness.These taxonomies were, however, based on 20th century media, and do not necessarily adapt well to analysis of digital news publication forms. The purpose of this study is therefore to find out which criteria are still relevant to the news selection behind a digitalformat such as push notifications; and which have become obsolete.The basis of this study is the criteria of news values originally designed by Galtung and Ruge in 1965 and revised by Harcup and O?Neill in 2001; as well as the model of assessing front page news proposed by Hvitfelt. The content analysis was conducted in a manner as similar to that of Harcup and O?Neill?s own study as possible, so as to constitute a re-revisal ?revamped for the digital age.Our results show that the criterion of ?frequency? ? that is the conformance between the time-span of an event and the publication frequency of a medium ? has acquired an ambiguous importance.

Digitala tjänstens registreringsprocess ? hur påverkar den helhetsintrycket?

The outset of this thesis is to raise questions on how we design for the mobile context and the capabilities of smartphones. Not only the presentation but also the use of input and interaction between a service and a user.This work evolves around sign up forms and answers the question: How does the sign up process affect the holistic perspective of a digital service regarding usability and user experience? This thesis consists of a case studies, and design experiments conducted on Twitter, Instagram and Randos sign up processes to explore if and how the usability, and the user experience could be affected and im- proved.This concluded some important aspects to be considered when designing sign up forms for a digital service.The usability, and the user experience is not only affected by user interaction, and the choice of input method but it?s also affected by which data the service is requesting, and more important; if that data is motivated to request by the service..

Posthumanism i förhållande till digitala spel

Detta kandidatarbete undersöker hur digitala spel kan skapas med någon annans synsätt. Vi ville se vad som hände om vi försökte göra spel på ett posthumanistiskt sätt och om detta hade förändrat något. Det har uppkommit speciella möjligheter och konsekvenser under processen, det har även dykt upp frågor. En av dessa frågor är hur skapandet av varelser inom digitala spel kan utföras. Likväl har det under projektet skett diskussioner och tester runt hur ett verktyg för detta ändamål skulle kunna fungera.

En ny teknikkultur : äkthet i sociala medier

Denna studie ger ökad kunskap om hur en digital artefakt inom sociala medier skulle kunna uppmuntra till äkthet, som en motpol till profilering för att skapa en balans mellan profilering och äkthet. Studien barhandlar området ?hur och varför användare presenterar sig och för sig på ett visst vis i sociala medier?. Detta förstås och diskuteras med hjälp av de två ändpunkterna äkthet och profilering. Studien berör även designerns roll i detta sammanhang.Studien undersöker området genom en litteraturstudie, samt en egen kvalitativ studie i form av semistrukturerade gruppintervjuer.

Mjukvarubaserad 3D-renderare

Abstrakt Produkten som jag har utvecklat är en mjukvarubaserad 3D-renderare. För att göra en sådan produkt är man tvungen att gå djupt in i området 3D och utföra alla beräkningar på egen hand. Dessa tar annars grafikkortet hand om. Denna rapport förklarar varför jag har valt att göra en egen mjukvarubaserad 3D- renderare och vad den är för något och i vilka områden den används. Här förklaras även min syn på programmering, digitala spel, vad programmering innebär för mig och hur min syn på spel har påverkat mig med tiden. Jag tar även upp mina tankar om spelindustrin och samhällets misstolkade värderingar av spel samt vad för sorts spel jag anser skulle gynna mänskligheten i framtiden. Vad jag tycker om utbildningen Digitala spel nämns också samt hur jag tror att den skulle kunna förbättras. Slutligen följer en kortfattad beskrivning av hur mitt projekt har genomförts. Abstract The product I have been developing is a software based 3D renderer.

When 2 become 1 : En studie kring betydelsen av samarbeten mellan artister och företag

The aim of this study is to create understanding of why companies should collaborate with artists and how artists and businesses build strong partnerships. We also want to understand the development of relations between the music industry and companies, together with the problems, possibilities and implications it has for both artists and corporate identity and brand. The music industry has been changing rapidly during the digital revolution and new problems and opportunities have emerged which the music industry can choose to either embrace or renounce. This study is made with a qualitative approach based on interviews with relevant individuals from the music industry. We have carefully chosen these individuals to counterpart different segments of the music industry and to execute our purpose from various perspectives.
