The main purpose of this study is to investigate the unintentional learning that happens during the use of computer games. With the use of interviews with students in the ages 13-15 who all have played the game series Assassin?s Creed, and then compared them with students who does not play the game, we have been able to identify that some learning is taking place, but that the student?s attitude towards the subject, and their maturity, also is vital for the learning. Even tough, the students who didn?t really enjoy history as a subject showed better knowledge after playing the game, than the students who hadn?t played at all, which indicates that computer games can be a good source for learning.

This master thesis deals with computer game classics and a possible computer game canon. It looks closer at four computer game genres - adventure, RPG, action and strategy - in order to discern which games are considered classics and what characterizes them. To answer the first question a quantitative research method was used. 675 computer game reviews from 5 Internetsites were examined in order to see which games are mentioned most often in this context and therefore might be considered classics. To answer the second question a qualitative research method was used.

In order to be able to change, to maintain competitiveness as a company in a world where rapid changes is part of the daily life, it is crucial to have knowledge and methods in how to change. One method, originally developed in Finland, is the Change Laboratory. This method is said to be efficient, not only concerning change aspects but also learning, since change and learning in this method is intertwined. This Master Thesis (20p.) tells about the process of conducting a Change Laboratory with a Swedish high-tech company and analyses factors in the process that makes change possible..

 Syftet med den här studien är att undersöka vilka yrkes- och studiebakgrunder yrkesverksamma datalärare har och om olika bakgrund leder till skillnad i uppfattningar om deras yrke och utbildning. Dessutom syftar arbetet till att undersöka hur datalärare håller sina ämneskunskaper ajour och om det finns skillnader i fortbildning beroende på utbildning och yrkesbakgrund. För att besvara arbetets frågeställningar används en kartläggande kvantitativ enkätundersökning som besvaras av yrkesverksamma datalärare från hela landet. För att få fram resultaten görs vissa sambandsanalyser och dessutom presenteras deskriptiv statistik. Undersökningen visar att majoriteten av datalärarna saknar lärarbehörighet samt att ungefär hälften tidigare har arbetat utanför skola och har professionella tillämpningar inom sitt ämne.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

Detta arbete behandlar hur Bluetooth fungerar samt säkerheten kring Bluetooth och några allmänt tillgängliga attack verktyg. Syftet med uppsatsen är att försöka fastställa hur säkert Bluetooth är i dagens läge. Bluetooth har länge varit tillgängligt för att utbyta data över korta avstånd.

För att kunna genomföra denna undersökning så har vi satt oss in i hur Bluetooth fungerar, vilka allmänt tillgängliga attacker och implementationer av dessa, som finns.

The aim of this essay is to describe the historical development of the intercultural teacher training program at Södertörn University in Stockholm. I have also examined how the intercultural teacher training program was started, how and why it became intercultural and how the people in charge of the development of the teacher training program discussed intercultural science. The teacher training program has been an active part of Södertörn University since 1998, but it became intercultural in 2002. I have studied these questions through documents from the Södertörn University archives and literature by the funders of the education. The study shows that the university profile, ambitions and motives have been a key factor in the decision to make the teacher training program at Södertörn a multi-cultural one..

Very few people have any knowledge how to protect themselves from theese threats..

The aim of this study is to highlight the computer as a learning resource in the education and give us knowledge about how the students uses the computer in year one in a selected High School where one computer per student were introduced in autumn 2011. The aim is also to contribute to the discussion about how the computer can become a natural learning resource for all students in all subjects, including the students in need of special support.How are the High School students using the computer?Are there differences in computer use, whether the student is in academic or vocational program?Are there differences in computer use between boys and girls?Do the student experience that the digital competence is increasing together with if they experience the computer as aid?In what degree do the teachers encourage the students to use the computer?How much do the students use the computer to learn mathematic?The study is based on a survey of all students in year one in a municipal High School.The result of the study is showing that the students first of all use the computer to play music, surf the Internet and to be logged in on social media (eg. Facebook). The students have learned to use the computer for the tasks they need, although the teachers don?t encourage the students to use the computer in any higher means, not in mathematics and not in other subjects.

AimThe purpose of the study was to investigate how upper secondary school students experience performance demands during their physical education and health classes (PE-classes). The questions were as following: Are there differing perceptions between the sexes whether students experience performance demands? In what situations do the students feel that the demands on their performance are high during PE-classes? Do the students experience of demands on performance differ whether the physical education and health teacher is male or female? Do students feel unfairly treated by the physical education and health teacher during PE-classes?MethodSeven upper secondary schools in Stockholm?s administrative district were randomly selected to participate in the survey. The principals were contacted for further information and to set a date for performing the survey. The project leaders were present during the days the surveys were taken by students in the social science and natural science programs.

Today?s cell phones include more and more functionality, it is no longer uncommon to be able to connect to the Internet or take photos with the cell phone. In this thesis the question is if the cell phone users are interested in this new functionality. Are there people who are interested in a cell phone that in this thesis is called ?Basmobilen? (the entry level phone), which include the following functions; phone call, SMS, phone book, calling lists, clock and the possibility to change the call signal.

Ibland kan det förkomma problem mellan utvecklare och kund/användare då de tar fram kraven till ett nytt system. En anledning till detta kan vara att utvecklingsgruppen och användargruppen inte har samma kunskaper och erfarenheter och talar då inte "samma språk". En lösning till detta problem kan vara att ta hjälp av en mockup. En mockup är en fysisk och/eller interaktiv modell av ett gränssnitt. I detta arbete har vi, med hjälp av intervjuer och observationer, undersökt om detta hjälpmedel underlättar kommunikationen i verkligheten..

The purpose of this study was to investigate how high school students felt that the computer helped or hindered participation and self-esteem in the learning situation and if the students experienced any differences between when they had been relatively alone in using a computer compared to when everyone had their own computer. The starting point was the national one-to-one projects made to give every student access to a personal computer and how it affected students in special educational needs and previous research. The theoretical approach was based on socioculture/activity theory and theories of self-esteem. Ten high school students in grade one at a senior high school that previously had started up a one-to-one project was interviewed. The results showed that the students primarily used the computer to write and to search the Internet, but even as a alternative or compensatory tool.

This report is focusing on problems with introducing standard enterprise resource planning systems (ERP) in businesses. A study has been carried out on a service and support department at a Swedish heat metering company, SVM North Node. The study aims to help the company become a better customer in choice and customization of a new ERP system. We make a description of the department studied and the work carried out there, on the basis of learning, knowledge and cooperation. As a final point we present some ideas on how computer systems could support their work, hoping that this will result in them making adequate demands on a new ERP system.
