    Agil Systemutveckling: En studie av kravhantering och beställarroll i agila angreppsätt2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper is a degree project on the C-level, 15 points at University West, Department of Business and IT dept. Informatics. This study is about agile methodology and its impact on IT projects. Requirements management is a process within an IT project, where customer has certain requirements that must be met by an IT system. The difference between the traditional and agile development is in the requirements management process and it can cause problems in a project. Requirements change during IT projects and to manage requirements, agile principles apply. Specification and planning in the waterfall model is time consuming. Working agile means to have close contact with the client. This minimizes the risk of project failure. With agile methods, functions can be developed at a faster rate and the customer receives prompt delivery. There are currently several different methods for systems development and project management. Some are based on research, others are new and some have been around a long time in the IT world. This work has identified customer involvement; Risk Reduction and Delivery which contribute to several projects fail under traditional systems. Agile methods are flexible, agile and welcome change and the customer will be able to steer the project. Agile methods have however provided the opportunity for developers to more quickly deliver functionality to the customer.

    Hur väl använder Sveriges stor- och retailbanker alt-attributet på webben?: En kvantitativ undersökning om webbtillgänglighet2023Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    Images are widely used on the internet today. For a part of the population these images are not accessible. Individuals who need a screen reader to access the web content must rely on the use of the alt attribute instead. This research examines web accessibility in Sweden’s commercial and retail banks through quantitative content analysis. We think this research subject is interesting because web accessibility is crucial for people’s online inclusiveness. The purpose of this study is to raise awareness among web developers about web accessibility and to evaluate the use of the alt attribute by the represented banks. 

    Our result points to an understanding throughout the web development community that the alt attribute should be used in the img tag. Though, we find a misunderstanding about how the alt text (text that describes an image) should be used in different types of images. Most of the improperly used alt texts were found in the decorative images. However, when the alt text is used correctly, we can also see good quality in the written text.

    RISC Architecture Compared to x86_64Architecture in Servers2021Independent thesis Basic level (professional degree), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    This examination work is about a comparison between the RISC-architecture, in this case ARM, and x86_64. The question of if RISC is the future of data centers and other server environments is a key point in this report. Using a multitude of tests such as processor performance (ops/s), memory throughput (MiB/s), temperature (°C), and power usage (Watt) several method scenarios are performed. In the report it is shown that RISC is much more effective than x86_64 and only has a marginally smaller performance difference. In conclusion, the report shows that RISC is a more efficient choice overall compared to x86_64.

    Fria och öppna programvaror inom kommunal verksamhet: Vägen mot öppna standarder?2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report deals with the attitudes within municipalities of open source software and open standards and if open source software may be an option to gain open standards. The aim has been to find out if open source software and open standards would be able to solve the lock-in problems that municipalities have against proprietary software. The study is conducted as an exploratory, inductive and qualitative study with depth interviews of subjectively selected informants as data collection method. A literature review has also been implemented by the relevant books and articles. Some economic determinants of municipalities to make use of open source software have not been considered in this study. The informants used in this study are all IT managers in a Swedish municipality and our key informants have been selected in a subjective manner based on the expertise they have in the subject. The conclusions drawn were that municipalities have been difficult to define standards and open standards, and that they do not automatically see the connection between open standards and open software. They also see different areas of interest for standardization.

    En jämförande studie av analysverktyg i QGIS och ArcGIS utifrån ett användbarhetsperspektiv2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Geographic information system (GIS) is a computer system used for various purposes. The main purpose is to analyze different data to give a clear picture of what reality looks like based on measured data. The choice of a GIS program is at least as important. There are different types of GIS programs, those that have a license fee and those that are free. The work will focus on two well-established GIS programs: ArcGIS (license cost) and QGIS (free). The purpose of the work is that it should be an aid for users of GIS to choose which program suits their purpose. In order to fulfill the purpose, a closer examination is made in the programs. The survey was based on selected questions and tools. The work is aimed at those who are already familiar with GIS software.The method that has been used in this essay is data collection because the work has been based on experiments to test how fast the programs are able to produce a result, in other words the process time. Literature has been used only to explain the analysis tools included in the work to provide an overall understanding of them. Most analysis tools in each program have been tested a number of times with the collected data to measure process time and whether there are differences in the results produced. These aspects have a major impact on financial sustainability because municipalities, companies and individuals who use GIS pay a lot of money to use GIS programs that are not free.The analysis tools that have been used in this work are buffer, shortest path, overlap analysis, nearest neighbor, TIN interpolation, spline interpolation and IDW interpolation. The reason for choosing these tools is that they are commonly used in analysis. In each program, these tools have formed the basis for the comparison of the programs. The results of the tests vary from tool to tool. It is largely not possible to claim that one program is better than the other, but depending on the purpose of the user of the GIS program, it is possible to claim that one program is better than the other on some analysis tools

    Robotiserad processautomation inom kommunal verksamhet: En kvalitativ studie om hur automatisering med RPA påverkat en kommun2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the society we live in today analog techniques have been replaced by digital tools. Processes that used to handle forms or letters are now processed in an electronic way which users can access by using a computer, phone or tablet. The function to read, write or send different kinds of documents has been digitized. In an office environment there are monotone and repetitive tasks that are manual, which can be time consuming. Robotic Process Automation (RPA) is a growing automation method which is being used more in municipalities, bigger corporations and organizations to handle these kinds of tasks. With RPA it is possible to make processes more effective in a way to relieve a human resource from time consuming tasks to give them time to do something else of more importance. 

    The purpose of this study is to examine how automation with RPA affects a municipality. What the positive or negative aspects are, and how the attitude of the employees is towards RPA. 

    To collect data qualitative methods have been used with semi-structured interviews and interview guides. A total of six persons from a municipality in Västra Götaland have participated in this study. To analyse the data from the result the literature review has been used as a starting point. 

    In the study it shows that RPA is mostly suitable for repetitive tasks that contain structured data. A robotized process saves both money and time and gives the employees time to focus on tasks that have a higher priority. Some employees have also been worried that they would be replaced, which is one of the challenges with RPA.

    Acceptans och användandet av Internet of Things-teknik i hemmiljön: En undersökning av IoT i hemmet med hjälp av UTAUT Modellen2021Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    IoT, or the Internet of Things, is developing rapidly in our society and this means that there are results in almost all areas, from households, finance, healthcare to smart cities, energy and much more. IoT is something that is on the rise and something that many would consider to be the future. The ability to control, measure and control things automatically, in sync and through apps is what made it slowly but surely weave itself into most homes. In healthcare, it adds another layer of security where things like bracelets can measure differences and deviations in such things as heart rate and other values. The UX design for a single object aims to meet the costumer’s expected needs for the device to be efficient to use, leading to the common goal of and IoT device. Simply put, the goal of IoT is to enable people to live better, work smarter, generate revenue and reduce costs. 

    The purpose of this study is to investigate why people use or do not use this technology in the home environment. But also examine how it is used and determine what affects what is being used. By conducting a quantitative survey with elements of qualitative questions where empirical data is collected, the answers are then interpreted with a modified version of the UTAUT (Unified theory of acceptance and use of technology) model.

    How the use of E-Learning can improve students’ learning process in a Developing Country: A Study of Imo State University (IMSU)2021Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The research examine how e-learning platforms can aid teaching and learning among students at the Imo State University in Nigeria. This study will furthermore identify opportunities students derive in using e-learning platforms and the students' challenges surrounding the adoption and use of the e-learning platforms. 

    The research was based on the qualitative method approach through which data will be accessed and collected. Qualitative research is based upon the ontological assumption that humans socially construct and produce reality. The researcher uses primary data to conduct a semi-structured interview with 10 participants from the Imo State University. Thematic codification was used to analyse the research data into themes, coupled with the theoretical approach for the research study.

    In the study, the results revealed that students appreciated the usefulness of e-learning during this pandemic era to be very effective for teaching and learning, especially with the restriction of social gathering. Students accepted the benefits of e-learning platforms to be influential in the period of the covid-19 for education through information technology. Students exposed to information technology and opportunities appreciate the usage of information communication systems. E-learning has also enhanced learning and development as far as information technology is concerned. The common challenge for using information technology generally in Nigeria is the lack of a constant power supply. 

    The research limitation lacks detailed hypothesis testing, and scientific testing should encourage the established complete findings of the research. Finally, time constraints limit the researcher to apply all the data and information collected to be incorporated into the study, leading to better and comprehensive research outcomes.

    The zoom application was very effective and efficient in delivering teaching and learning during the COVID-19 restriction and lockdown. TAM model was used to measure how many students accepted technology usage as perceived usefulness for information technology. E-learning gives significant opportunities for students through teaching and learning accessible to all.

    Sociomateriality and design – How do we un-pack technology for knowing in practice?: Research in Progress/Workshop2016Conference paper (Other academic)
    Abstract [en]

    Blended e-learning permeates flexibility and school is no longer the only place for learning, rather through e-learning courses new ways of building competences throughout life and integrated in the workplace can be accomplished. Technological artifacts, the material itself do not create learning,rather, social and pedagogical aspects from a participatory perspective in e-learning courses is needed to balance the impact of technology. Challenges to reach balance between material and social is in this paper illustrated as a sociomaterial learning practice through a work-integrated e-learning (e-WIL) project between a university and collaborating manufacturing industries. This learning practice comprise design of e-learning courses, target industry knowledge needs to reach for being a competent employee. Teachers' and course participants' activities show various challenges of work integrated e-learning. Early results from focus group sessions and observations are categorized as knowing-how to design and use digital learning technology, knowing-what knowledge to be learnt for work practice and knowing-when to use new knowledge in work practice.

    Work-Integrated Learning and Co-creation of Knowledge: Design of collaborative technology enhanced learning activities2014In: Proceedings of the 37th Information Systems Research Seminar in Scandinavia (IRIS 37) / [ed] Ahmad Ghazawneh, Jacob Nørbjerg and Jan Pries-Heje, Ringsted, 2014, p. 1-15Conference paper (Refereed)
    Abstract [en]

    In this paper we aim to understand management’s perceptions of knowledge and competence development to inform the design of technology enhanced learning activities integrated in the workplace. Work-integrated learning can be viewed with the university lens on studies of formal education integrated in the workplace setting, but here we rather emphasize the conditions of the workplace as implications for design of successful e-learning initiatives. We conducted interviews with 15 manufacturing industries in Sweden and used qualitative content analysis approach to interpret the text data. Results show that companies describe a rich variation of work-integrated learning activities, but the step towards external collaboration with academia for co-production of knowledge is marginal. Also, broad-minded work for innovations is limited. This imply the need for well-planned design of richer collaborative acitivites between academia and organizations through use of media technology to encourage competence development.

    Learning Aspects for Manufacturing Enterprises within Aerospace industry entering into Quality Standard AS91002011In: 24th ICDE World Conference on Open and Distance Learning: Expanding Horizons- new approaches to ODL, 2011, p. 1-11Conference paper (Refereed)
    Abstract [en]

    The aerospace industry is expected to grow substantially during the next two decades. As a result more suppliers aim for entering into this industry. Demands on safety and quality in this sector are particularly high, where SME´s must upgrade from the generic group of quality standards, the ISO9000 family, to AS9100, the aerospace standard. In this research we focus on the meaning of learning processes for successful implementation of quality standards in a workplace context at a manufacturing company. By using Blooms Revised Taxonomy of learning, we can understand, evaluate and design actions for continuous improvement which can be supported by an IT-based tool for self-assessment supporting organisational learning and implementation of the Quality Management System.

    En mobil evenemangsapplikation i Trollhättans utveckling mot en mer attraktiv stad2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this study, a prototype of a mobile application that collects local event information, has been created. Local events are a contributing factor to increased economic growth and how individuals experience a city as a whole. Because of this, it is vital that information about local events reaches inhabitants. This information is currently distributed in both social media, websites, newspapers and bulletin boards. Due to the fact that the information is currently scattered, inhabitants in the city feel that they are not reached by all information about local events. The aim of the study is to develop a design proposal on a mobile application that can be used in future development and implementation of the application. Through qualitative interviews with students at the University of West, a need for an event application has been identified, proposals for features and content have been developed. Based on these interviews and previous research within areas of usability, user experience, design principles and interaction design a prototype has been designed. To confirm that the prototype produced was considered useful and had good usability five structured usability tests were performed with potential end users. The result of these shows that the study has developed a useful interface and that the general perception of both the interface and the application was its simplicity. The conclusion of the study is that the designed prototype is appropriate and useful which will enable the interface to be used as a basis for future development of the application.

    SQL vs NoSQL: En prestanda jämförelse2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this paper we compare the performance of a NoSQL database and a MySQL database. The execution time is measured for a variety of different operations, such as read, write and update. We will also perform tests on a denormalized MongoDB database when the tests uses more than one collection. A small amount of structured data is used to model a fictive taxi company. The tests are written in Python and are performed in a virtual environment. The paper goes through the history behind relational databases and NoSQL types, and also covers both MySQL and MongoDB, which is the database managers used in these tests. They are chosen because they are the most popular on the market. Results show that MongoDB is quicker than MySQL when the operations are performed on a single collection/table.

    Effektivisering av administrativa uppgifter i nätverk2022Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [sv]

    Att administrera ett nätverk är en viktig uppgift som kan vara tidskrävande. Många uppgifter är rutinmässiga och utförs på samma sätt varje gång. Enkla konfigurationsuppgifter kan, på många enheter, förbruka en stor del av arbetstiden för nätverksadministratörerna. Ett litet misstag kan orsaka nätverksavbrott, som kan ha stor inverkan på verksamheten. Genom införandet av automatiseringsverktyg, kan nätverksadministrationen effektiviseras, tidsparas, och risken för nätverksavbrott minskas. Det ger nätverksadministratörerna möjlighet att fokusera på andra viktiga uppgifter och ökar deras produktivitet.

    Den här studien har undersökt om administrationsuppgifter i nätverk effektiviseras med automatiseringsverktyg, genom att tiden det tar att manuellt logga in i varje enhet och utföra kommandon, jämförts med tiden det tar att utföra samma uppgift med automatiseringsverktyg.

    Resultatet visar att man sparar tid med automatisering och att effektiviteten ökar med antalet enheter i nätverket

    "Man behöver ju kommunicera på andra sätt, och då är det väldigt smidigt att kunna göra det centralt på en lärplattform": Komvuxlärares upplevelse av digitala lärplattformar2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    As a result of the ongoing worldwide pandemic of coronavirus disease the Swedish colleges, adult schools and high schools closed and switched to distance education. Beside the pandemic a report from the Teachers' Union was published in which it was found that many teachers are dissatisfied with the learning management systems used. The digitization of the school thus became a highly relevant area during this time.

    The purpose of this essay is to investigate the municipal adult education teacher's experience and use of learning management systems and thereby highlight what they see for challenges and opportunities with the learning management systems and if it has an impact on the actual usage.

    This paper is expected to respond to how teachers in Swedish municipal adult education feel that it is to work with learning management systems. To answer the question, a qualitative starting point is used, where semi-structured interviews have been used. In this study, the theoretical model UTAUT is used to analyze the result. The four constructs from UTAUT are used to categorize and identify the teachers' experiences, to better answer our research question.

    Ten municipal adult education teachers from four different schools in Västra Götaland, Sweden participated in the study. In the study, we could see that the most common area of use for the learning management system seems to be to communicate and to make materials accessible to students between classes. In addition, we could see that the teachers felt that their level of technical experience were somewhere between medium and high, all had some type of education and training in how to use learning platforms, however, more teachers described that there was a need for more education among colleagues. Advantages of learning management systems that most teachers described were increased efficiency, communication and accessibility, disadvantages that teachers described were legal security, integration, compliance with law and feedback. In general, the teachers seem more positively attuned to the platforms than negative. From the UTAUT model, we could see that all factors affect the teacher's intention and the actual use of the platform positively, however, some parts of the effort expectancy can negatively affect the teacher's intention to use.

    Immersive navigation system for vehicles using AR, a VR proof of concept experience.2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This master's thesis explores the design principles and user preferences for immersive navigation systems in augmented and virtual reality, with a focus on enhancing the driving experience and improving safety. Drawing on Action Design Research methodology and flow theory, an artifact and valuable insights were obtained from 13 interviews. Four design principles emerged from user preferences and aligned with flow theory: Personalized Navigation, Contextual Driving Guidance, Simplified Information Display, and Familiar and Consistent Navigation Feedback. These principles emphasize tailoring the navigation experience, providing relevant information, presenting it clearly, and offering timely feedback. They serve as valuable guidelines for the design and development of immersive navigation systems that enhance the driving experience and promote safety. 

    The study also examines the implications of using virtual reality for testing and showcasing navigation systems designed for augmented reality or the real world. Despite challenges such as motion sickness and technical limitations, virtual reality shows promise in simulating immersive experiences beyond the capabilities of current augmented reality technologies. Factors such as embodiment and the alignment of virtual and physical elements are identified as critical for enhancing immersion and reducing discomfort.

    Overall, this thesis provides a preliminary understanding of user preferences and lays the groundwork for future research to further investigate and refine these design principles. It contributes to the development of immersive navigation systems that offer drivers a more accurate and engaging view of their surroundings, thereby enhancing the driving experience and improving safety.

    Kundportal med Microsoft Azure2021Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The company B3 wants a prototype of a customer portal to examine if the Azure AD B2C service works for identity management. Therefore, this project examined if Azure AD B2C is useful as an identity manager for a customer portal and how multi-factor authentication and privilege works within the service. There have also been requirements from the company on a few functionalities on what should be included which got implemented. These functionalities were for instance that the user should be able to create an account, log in, and the ability to invite other users if they have the right authorization level. Microsoft Azure is a cloud platform service which is owned by Microsoft and has a lot to offer. This has meant that while working with the project, there has been a lot to learn within Microsoft Azure. This has been done in the form of research where, for example, various services have been investigated in how they work and how these can be used in the implementation of the customer portal. The customer portal was built through the framework ASP. NET Core with the programming language C# to interact with Azure AD B2C. The functionalities that were included in the portal were taken from the requirements that were given. The final product consisted of a functional portal with an interactive interface which will make it easier for the company to expand on. The actual portal includes functionalities for logging in, group management, and the ability to invite other users.Azure AD B2C supports the functionality for multi-factor authentication and different types of multi-factor authentication methods. For privilege, can the service create groups which can divide the users. These groups cannot implement the privileges, this must be done within the applications that uses the service. All the requirements for the customer portal made the company satisfied except for one requirement which will be improved at a later opportunity. The requirement was how a user can be invited to the customer portal which works but not in the way the company expected. When it comes to the implementation of the functionalities, the basic was easy but got more advanced for the more complex functions.

    De formade ögonbrynens ilska: Queer coding inom Disneys porträttering av manliga skurkar2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study aims to examinehow and what Disney communicate to their target audience, by analyzing the four animated feature films Peter Pan (1953), The Lion King (1994), Pocahontas (1995), and Princess and the Frog (2009). The animated movies have been analyzed through a qualitative method to get a better understanding of how Disney portray their male antagonists through queer coding. Through semiotics, and Peter Dahlgren's approach to analyzing media texts, we have gained a deeper understanding of what Disney is communicating. The study shows that there are many obvious cases of queer coding because of the stereotypically feminine way that the male villains are portrayed. The villains show signs of this femininity through everything from facial features to bodily movements. Through this detailed analysis it has come to our attention, that there is no doubt that the villains are being portrayed in a much more feminine way in comparison to the remaining characters in the movies.

    Encrypted media streaming over 4G (LTE) with Raspberry Pi2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis is to explore the possibility of building a more secure and better streaming solution than publically available. The available solutions today are in our opinion mediocre in quality and are often missing older and unknown artists. A prototype will be built and tested in a variety of different scenarios where the prototypes capability will be tested to the fullest. The result is a working streaming solution where good quality and security is a fact. The finished prototype has a few limitations, but overall it's a good working solution.

    Comparing Pixel-based Quality of Experience in Remote Desktop Applications2020Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Few tools are targeted explicitly to remote access and remote desktop performance, those who do, are highly specified to the scenarios they were designed for and are therefore limited in their application. Since Quality of Experience (QoE) is a problematic term to pinpoint, as it is, by definition, subjective and will therefore differ between users, it encourages the use of a tool that can measure performance. This paper examines whether a universal tool can be used to compare remote desktop applications from a QoE perspective. By focusing on what is displayed, rather than how the remote desktop application displays it, this angle ensures that the measurements taken are independent of what remote desktop protocol or application are used. With the goal to able to measure a difference between two tests, two applications, TeamViewer and RealVNC, were used to connect to a machine and perform a series of pre-scripted actions. Tests with varying network latency were recorded in the form of screenshots, which were then analysed by a program that can detect colour differences in pixels between two tests. The results show that there is a measurable difference between the two different remote desktop applications, which gives hope that in the future a universal method can be developed to measure the Quality of Experience of remote desktop applications.

    WhatsApp som shadow-IT för intern kommunikation mellan medarbetare inom vården: En kvalitativ studie om tillgänglighetens påverkan på arbets- och privatlivet2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The use of social media is growing both in private life and in work life. Using social media as a communication tool in the workplace entails the need for adaptations in the way of working, but also an understanding of how it affects the privacy of employees. Previous research shows that there are both advantages and disadvantages to the use of digital communication tools in workplaces. Previous research in the subject mainly focuses on how the business and the way of working are affected, less focus is placed on how the employees actually use digital communication tools to facilitate internal communication and how their well-being and privacy are affected. The following study investigates how the employees, at a clinic in Sweden, use WhatsApp as a communication tool and source of information, i.e. shadow-IT which means that the user uses IT resources that have not been reviewed by the IT department. But also how it affects the employees' privacy as a result of the constant connection to the workplace. The purpose of this study is to investigate the use of digital communication tools at a specific clinic in Sweden. The study will identify in what way and for what purpose the employees use the digital communication tool WhatsApp, how their private and working lives are affected by the use and which advantages and disadvantages exist in comparison to traditional approaches to internal communication. From this, the following questions were formulated: For what and how is WhatsApp used in the clinic? and How is the private and working life of the employees affected by using WhatsApp in the clinic? 

    To investigate these, semi-structured, individual interviews were conducted with eight employees at the clinic. According to the results of the study, it was found that the main advantage that WhatsApp contributes is that the spread of information is faster, unlike previous methods of communication. The main disadvantage that the respondents emphasize is that you are never completely free. However, all respondents, except those who hold a leadership position, believe that themselves do not feel stressed by the connection and that it does not affect their privacy negatively. This is because they turn off the notifications from WhatsApp.

    Critical Imaginaries and Reflections on Artificial Intelligence and Robots in Postdigital K-12 Education2019In: Postdigital Science and Education, ISSN 2524-485X, Vol. 1, no 2, p. 427-445Article in journal (Refereed)
    Abstract [en]

    It is commonly suggested that emerging technologies will revolutionize education. In this paper, two such emerging technologies, artificial intelligence (AI) and educational robots (ER), are in focus. The aim of the paper is to explore how teachers, researchers and pedagogical developers critically imagine and reflect upon how AI and robots could be used in education. The empirical data were collected from discussion groups that were part of a symposium. For both AI and ERs, the need for more knowledge about these technologies, how they could preferably be used, and how the emergence of these technologies might affect the role of the teacher and the relationship between teachers and students, were outlined. Many participants saw more potential to use AI for individualization as compared with ERs. However, there were also more concerns, such as ethical issues and economic interests, when discussing AI. While the researchers/developers to a greater extent imagined ideal future technology-rich educational practices, the practitioners were more focused on imaginaries grounded in current practice.

    Hur rendering påverkar prestanda och sökmotoroptimering: – NextJS vs React2021Independent thesis Basic level (degree of Bachelor), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    Frameworks have had a big influence on how websites are structured. They give developers an opportunity to create websites which previously were seen as too complex. React is the most popular framework and will be compared to NextJS which is based on React but with extra features. The biggest difference between the frameworks is how the websites are rendered, NextJS uses server-side rendering while React uses client-side rendering. In the test, loading time and SEO will be compared between the two frameworks. Three tools are used to test the websites, Chrome Developers Tools, Lighthouse and Apache Bench. Two applications are created, one in each framework and contains a navigation, text, data from an API and a footer. The results show that React is faster in most of the tests and just as good as NextJS at SEO. In the first page load, NextJS has a shorter average loading time per resource but needs to load additional resources, which is why React is faster. The results do not match the previous academic studies which can be because of the applications we created not being big enough. Our conclusion is that React has a better performance and equally good search engine optimization asNextJS. Continuation of the report can be done by cooperation with companies that have websites which use either NextJS or React.

    Insamling av accelerometerdata med Linux som ett realtidsliknande system2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this paper a prototype is constructed with the purpose of collecting GPS- and accelerometer data from a small, electric vehicle. The collected data is sent to an external database, and visualized with Grafana. Accelerometer data is collected from sensors on the vehicle's front- and back axis, as well as a sensor mounted in between. Accelerometer data can be used to classify driver behavior, study the conditions of roads, and monitor wear and tear. The paper also explores how Linux can be used as a substitute for a real time system when it comes to collection of accelerometer data. The prototype's performance is compared to an ideal real time system as well as a general purpose system. Performance is measured by analyzing the timestamps of neighboring datapoints. The difference between two timestamps collected by an ideal real time system is exactly equal to the period of corresponding collection frequency. By optimization and using the PREEMPT_RT patch for Linux, the prototype can collect accelerometer data in up to 200 Hz, with a standard deviation of single microseconds for neighboring timestamps.

    Webbutveckling med ChatGPT: En undersökning av dess potential och användningsområden2023Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    In this study, we delve into whether ChatGPT can be a useful tool for web developers. For this study, we employed a comparative method with multiple experiments to investigate ChatGPT's potential and applications in web development. We chose to examine four areas that are prevalent in web development. These areas were code generation, code completion, code optimization, and code debugging. We constructed various prompts for the experiments we conducted. To assess ChatGPT's potential and applications in web development, we performed several experiments that involved testing ChatGPT's ability to generate code, optimize code, and solve coding problems. The results of these experiments indicate that ChatGPT is capable of generating code, providing suggestions for code optimization, and resolving coding problems. However, we also observed limitations in ChatGPT's ability to generate more advanced functionalities. Based on this study, we can conclude that ChatGPT has potential and capabilities. In theory, the use of generative AI could contribute to streamlining various tasks and potentially take over monotonous tasks. In its current version, ChatGPT can only serve as an assistant, but its future is likely to have an impact on web development.

    Vad har människor för behov och önskemål vid kontakt med vården via digitala verktyg?: En kvalitativ fallstudie på 1177 Vårdguiden2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The use of technology in our everyday life has increased and there are no indications that the use of technology will decrease in the near future. The development of technology means that healthcare services are being digitized and with that, the individual's ability to search for health information is increasing as well. Sveriges Kommuner och Landsting has developed four segments that describe how individuals act in contact with healthcare. To meet the needs of these individuals, the healthcare in Sweden has to find more ways to perform its services. The purpose of this study is to investigate how individuals in Sweden want to use the digital health tool 1177 Vårdguiden in their own care and to investigate whether the respondents identify themselves with any of the foursegments.

    To answer the study's question, a qualitative approach has been applied to the data collection. Data were collected through semi-structured interviews and a total of nine respondents participated in the study. To investigate individuals' needs when searching for health information, the results were analyzed with “health information behavior” as a theoretical frame of reference.

    The study shows that the respondents can imagine themselves using digital health tools in their everyday life. According to the answers of the respondents, they want to use 1177 Vårdguiden to search for information, read about symptoms and book appointments. It also appears in the study that the segments that Sveriges Kommuner och Landsting has developed agrees with the respondents to a certain extent, but based on the answers of the respondents there are opportunities to create more.

    Making sense of social media implementation: a longitudinal case study of the technological frames of hotel employees2017Conference paper (Refereed)
    Abstract [en]

    Social media has become an important part of people’s social life and effect how they communicate, interact and consume online. Social media, has therefore also to a great extent been adopted by organizations in order to be used both for internal and external communication. The purpose of this paper is to study the adoption and implementation of social media in hotel organizations from the employee’s, or user’s perspective by applying the concept of “technological frames” with focus on the nature of technology, technology strategy and technology in use. The paper is designed as a longitudinal, qualitative case study consisting of data collected in seven European countries. In total 28 in-depth interviews have been conducted during 2.5 years. Findings show that the employees’ technological frames to a high extent has been constructed outside the organization during their private usage, or non-usage of social media, and that these frames affect how they use social media in the hotel organizations. The contribution is an insight into how technologies, like social media that is introduced to employees outside the organizational setting, are used during an implementation process within the workplace.

    Among Followers and Rebels: Professional Identity and Digitalization of Work2020In: Proceedings of the 53rd Hawaii International Conference on System Sciences 2020 Jan 7: Digital and Social Media in Enterprise, 2020, p. 1-10Conference paper (Other academic)
    Abstract [en]

    The digitalization of work practices has changed the conditions for many professions. In this study, we explore the relation between professional identity and digitalization in the workplace. We join the research stream within professional identity research that views identity as a narrative construction, a story that individuals tell themselves and others to tell who they are, in this case in relation to digitalization. The empirical data derive from two different contexts: Nordic primary school teachers and European hoteliers at an international hotel chain. In total, 72 interviews were conducted. The study contributes to existing literature by providing increased knowledge on digitalization of work practices by illustrating different approaches to digitalization of work that extend over a specific profession. Theoretical contributions involve suggesting four ideal types of categorization to explain the approach to digitalization in professional life.

    LAPSync: a Location-Aware Protocol for Remote File Synchronization2012Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Commercial provisioning of file synchronization services (FSS) relies entirely on protocols that utilize a remote central server that is often located in the cloud to host important files. Updates at user computers are propagated to the central server and from the central server to other sources in need of such updates. Therefore, a synchronization operation between two computers located on the same network often results in file data transmission to and from this local network at least twice. This introduces an unnecessary bandwidth usage on a user’s local network and has become an issue, especially since there is an increase in the demands for internet resources.

    This thesis work presents a new file synchronization protocol towards FSS known as LAPSync (location-aware protocol for remote file synchronization). This paper also proposes a hierarchical synchronization mechanism by utilizing LAPSync. Our proposed solution relies on the ability of LAPSync clients to acquire knowledge about the location of clients participating in the synchronization operation to construct a hierarchical synchronization path. Finally, we implement our protocol into a prototype and conduct experiments to compare with drop-box (a popular file synchronization service). The results obtained show that LAPSync offers a reduction in bandwidth usage when the files to be synchronized exist on the same local network

    Kommunikation för hållbar energianvändning i bostäder2019Report (Other (popular science, discussion, etc.))
    Abstract [sv]

    En effektivare användning av energi och minskat resursslöseri är viktigt för att begränsa klimatförändringar och arbeta mot en mer hållbar utveckling, inte minst inom bostadssektorn. Bostadens energianvändning är beroende av både de professionellas och hushållens agerande. I dag finns teknisk kunskap om hur vi utvecklar och producerar energieffektivaoch smarta energilösningar till bostäder och till den teknik som hushållen använder. Det finns också forskning om hur hushållen agerar och bör agera för att spara och effektivisera användningen av energi i hemmet. Ett mer angeläget problem är hur dessa grupper ska samverka med varandra så att energieffektivisering och besparing också genomförs. Det gäller såväl kommunikationen mellan professionella och hushåll, som de senares interaktion med den energiteknik som de professionella tillhandahåller.Syftet är att undersöka hur kommunikationen mellan professionella och hushåll kan utvecklas för att uppnå en hållbar energianvändning i bostäder. Rapporten baseras på en sammanställning av beteende- och samhällsvetenskaplig forskning som på olika sätt har behandlat kommunikation om energiteknik, energibesparing och effektivisering. Vi har även genomfört intervjuer med olika professionella aktörer vid ett energibolag. Avsikten har då varit att undersöka hur energibolaget kommunicerar om miljö- och energifrågor med hushållen. Vår bakgrundsförståelse utgår från tre olika kommunikationsstrategier; informations-, respons och medverkansstrategier, som grundar sig i delvis olika sätt att förstå vad kommunikationenmellan professionella och hushåll kan innebära.Resultatet från kunskapssammanställningen pekar på vikten av att, i kommunikationen med hushåll, utgå från deras egen energianvändning, energirelaterade vanor och val av energiteknik, liksom deras intresse och motiv till att spara energi. För att kommunikation om energifrågor ska upplevas som relevant och meningsfull för hushållen så räcker dock inte detta.Man bör även identifiera och/eller skapa adekvata tillfällen för kommunikation och sträva efter att budskapet liksom kommunikationen kan anses som trovärdig. För att nå fram är det också av vikt att tänka igenom hur man talar eller skriver om energifrågor, exempelvis att det som sägs och skrivs är tillräckligt begripligt. De professionellas kommunikation medhushållen sker även via tekniken. Att designa tekniken för god användbarhet och effektivare energianvändning är därför viktigt.Resultatet från intervjuerna med professionella aktörer på energibolaget VMEAB visar på olika former av kommunikationsaktiviteter såsom allmänt informationsmaterial som skickas till hushåll, digital kommunikation, reklam, evenemang och personlig kontakt. Intervjupersonerna lyfter fram vikten av att det som kommuniceras är begripligt för hushållen och att den information som ges ut varken är för omfattande eller knapphändig. Personlig kontakt medhushållen är eftersträvansvärt, men det är resursmässigt svårt att tillgodose. Energibolaget har en ambition att ytterligare utveckla kommunikationen med hushållen för att öka deras intresse och medvetenhet för energianvändningen. Insatser som då nämns är att synliggöra energianvändningen via en personlig hemsida, utveckla funktioner som ska ge direkt återkoppling mellan kund och bolag, samt se över möjligheten att vara mer informell i kommunikationen med hushållen.

    An mHealth artifact in home care: Professional progression through work integrated learning: Towards an IT supported caring conversations2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim is to study a problematic grocery-shopping situation within a home care organization, in one studied municipality in Sweden and for this, a qualitative action design research method is applied. As a solution to this problem, an mHealth (mobile health) artifact was developed and the thesis aims to study the developed solution and the WIL effects on the organization and the caring situation. The purpose is to emphasize on the perceptions of an mHealth artifact for the grocery shopping process as well as capture the early perceptions focusing on the values and effects for the different levels of engagement spanning the user groups involved. Then, finally investigating the effects on the caregivers’ competence development in relation to the mHealth artifact and the work integrated learning. This leads to the recognition of the need for a conversation between the caretakers and the caregivers. This results in the developed artifact, being found a conversational starter, nurturing and triggering a caring conversation, which leads to professional progression. This consequently, leads to higher quality of care and to the caregivers having more pride in their profession as well as having more time for the caretakers. This all concludes that technology will not replace caregivers. But caregivers, who use technology, will probably replace caregivers who don’t.

    Becoming a Designer: The value of sensitive design situations for teaching and learning ethical design and design theory2022In: Scandinavian Journal of Information Systems, ISSN 0905-0167, E-ISSN 1901-0990, no 1, p. 1-36Article in journal (Refereed)
    Abstract [en]

    Teaching and learning design theory are challenging tasks. To solely teach design theory through rules or codes of conduct, could be seen as a static way of approaching a complex phenomenon. In this paper, we argue for the importance of engagement in sensitive design situations, an approach that entails a process of de-emphasizing objectivity and promoting subjectivity through real-life sensitive cases to learn from, to foster reflectiveness for the future designers. This study aims to explore how sensitive design situations can be used when teaching and learning design theory. The research approach consists of a case study in a Nordic university, and a course in interaction design in a software engineering program. The sensitive design situation involves designing a digital artifact that can help children that have been diagnosed with cancer, cope with their cancer treatment. The main contribution is a teaching method for cultivating ethical design, which includes the application of sensitive design situations when teaching ethics to students. We illustrate that by forwarding three characteristics that can be used when teaching and learning ethical design through sensitive design situations.

    Jämförelse av prestanda för flatkabel (konsolkabel) vid olika hastigheter2023Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [sv]

    Denna rapport syftar till att ge en förståelse för flatkablars funktion och utvärdera effekten av olika kabellängder på dataöverföringshastigheten. Teoretiska beräkningar och praktiskatester genomfördes för att bestämma den maximala längden på flatkabeln för att uppnå en hastighet av 10, 100 och 1000 Mbit/sekund.

    Resultaten visar att kabeln bör ha en längd på max 0,1 meter för att uppnå enöverföringshastighet på 1000 Mbit/sekund. För 100 Mbit/sekund bör den vara max 2,25meter lång och för en hastighet på 10 Mbit/sekund bör den vara max 4,5 meter lång. Enviktig upptäckt är att vid större kabellängd än 4,5 meter tappas överföringshastigheten totalt. Det betyder att maximal längd på en flatkabel bör vara 4,5 meter och att längdenspelar stor roll för överföringshastigheten även när man använder kortare kablar. Vi testade också hastigheten i ethernetkablar på samma sätt. Rapporten belyser vikten av korrekt design och installation av flatkablar för att säkerställa optimal prestanda.

    Spine-Leaf med VXLAN: Hur svårt kan det vara?2023Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    This report aimed to investigate how difficult the configuration of a Spine-Leaf with VXLAN would be perceived to be by students schooled on the hierarchical CDA network model. Instead of using the help of a ACI controller, everything will be configured manually, and connectivity verified through ping and traceroute in each topology. The study also aims to investigate the protocols used and the number of configuration lines required to establish connectivity in the Spine-Leaf topology with VXLAN and the CDA topology with VLAN. Differences in performance or load distribution between the different topologies will not be investigated. To determine this, two scenarios were set up. Scenario 1 consisted of Spine-Leaf with VXLAN topology and scenario 2 consisted of CDA with VLAN topology.The results showed that according to the measurements of difficulty, it was harder to implement Spine-Leaf with VXLAN than CDA with VLAN. It was also found that more configuration lines were required to establish connectivity for Spine-Leaf with VXLAN compared to CDA with VLAN. Despite the fact that the test subjects perceived VXLAN as more difficult, they agreed that it provides a more robust network with features superior to those delivered by CDA with VLAN.

    Abstract [en]

    Every year businesses and individuals are exposed by Denial Of Service attacks with the intention of putting servers into disuse and make services unusable. We have investigated three different ways to protect a server and the internal network against Denial Of Service attacks in the most efficient manner. This study measure the CPU usage and response time before and during a DoS-attack to get an overview of how charged each unit is during an attack to compare each DoS-protection.

    The survey showed that the Cisco ASA Firewall protects the server and the internal network in the most efficient way because the device uses a deep packet filtering and inspection which involves a more advanced technology that is used to filter out inappropriate data-traffic

    Software architecture graphs as complex networks: a novel partitioning scheme to measure stability and evolution2007In: Information Sciences, ISSN 0020-0255, E-ISSN 1872-6291, Vol. 177, no 12, p. 2587-2601Article in journal (Refereed)
    Abstract [en]

    The stability and evolution of the structure of consecutive versions of a series of software architecture graphs are analysed using the theory of complex networks. Brief comparisons are drawn between the scale-free behaviour and second order phase transitions. On this basis a software design metric Icc is proposed. This software metric is used to quantify the evolution of the stability vs. maintainability of the software through various releases. It is demonstrated that the classes in the software graph are acquiring more out-going calls than incoming calls as the software ages. Three examples of software applications where maintainability and continuous refactoring are an inherent part of their development process are presented, in addition to a Sun Java2 framework where growth and backward compatibility are the more important factors for the development. Further to this a projected future evolution of the software structure and maintainability is calculated. Suggestions for future applications to software engineering and the natural sciences are briefly presented.

    An investigation of the merging and collapsing of software2007In: Advances in Complex Systems, ISSN 0219-5259, Vol. 10, no 3, p. 379-393Article in journal (Refereed)
    Abstract [en]

    We explore the use of complex networks for understanding of the interaction of computer software applications written in the Java object-oriented language with the "library classes" that they use (those provided by the Java Runtime Environment) as, essentially, a merged network of classes. The dependence of the software on the library is quantified using a recently introduced model that identifies phases close to a second-order phase transition existing in scale-free networks. An example is given of a piece of software whose class network collapses without the presence of the library classes, providing validation of a novel structural coupling measure; Rcoupling. The structural properties of the merged software-Java class networks were found to correlate with the proportion of Java classes contained within the subset delimited by Rcoupling. A mechanism for the preservation of the software class network is also provided for the cases studied where the removal of the library classes does not cause collapse.

    Användning av responsiv webbdesign för att skapa en användarvänlig webb: Webb- och enhetsanpassning utifrån olika åldersgruppers behov2020Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    Today, the internet is a big part of our everyday lives. We can scroll through social media, post pictures, share links and surf the web wherever we are thanks to the development of mobile devices. More than 50 percent of all internet use today is through mobile phones. Since the technological development is so big, this has also meant that web development and web design has had the need to develop parallel with the technology. In order for web pages to keep up with the technological development and to work on all types of devices regardless of screen size or screen resolution, the technique responsive web design had been developed. In responsive web design there are also several different methods to facilitate the work for responsive web design. In this report we will investigate some of these methods. Also, the web design concept "mobile first" and "one click away" will be discussed. In addition to the fact that the web has been forced to adapt to the technological development, we must not forget that the web should be a user-friendly place where all different age groups can interact with each other and with different types of web pages without difficulty or annoyance. It is important that all age groups are able to use the web and that it is adapted for different types of users so that all people are able to access and take part of the information that is available online.

    Den svåra konsten att samarbeta: En fallstudie om rollförändringar vid digitalisering av offentlig sektor2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    The purpose of this study is to create a deeper understanding of the effects of digitalization on individuals involved in a small size ongoing agile public sector development project. Our research question was: How does the digital transformation of society affect the requirement and development process in digitalization projects in the public sector, and what effects does this digitalization have on organizations and individuals? The main question was clarified using two sub-questions: (1) How are roles and expectations of the digitalization process changing? (2) What are the expectations on the product owner and how do they respond to needs and resources? A case study was conducted on a smaller, internal, agile development project at University West. Five key people, all with multiple years of knowledge in their respective domains and connection to the project, were selected and interviewed. A thematic analysis of the interviews was done, and three main themes were found: 'History', 'Current situation', 'Future'. These three main themes and associated subthemes then formed the basis for analysis and discussion regarding digitization.

    This study is very small and therefore it is not possible to draw general conclusions from the results. On the other hand, the unique characteristics of the researched project can give a deeper understanding by clearly displaying the problems resulting from lack of knowledge transfer and unclear roles. Unspoken role expectations and unclear role definitions appear to prevent knowledge exchange and learning

    Benefits of Alternative Network Topologies For COTS Linux Clusters2006In: Proceedings of the International Conference on Applied Computing: San Sebastian, Spain. Feb 25-28, 2006, p. 457-461Conference paper (Other academic)
    Abstract [en]

    The focus of this paper is to evaluate the use of two different network topologies for Ethernet networks in small Common

    Off The Shelf (COTS) clusters. The fully meshed network topology was evaluated and its impact on latency and

    bandwidth was measured and compared to the more traditional switched network topology. This was done at MPI level

    by measuring the point-to-point round trip latency (ping-pong) and all-to-alla bandwidth for different sized messages.

    The results from the experiments are presented and the overall the benefits and drawbacks of the both approaches are

    discussed.

    A Kenyan Cloud School: Massive Open Online & Ongoing Courses for Blended and Lifelong Learning2013In: Open Praxis, ISSN 2304-070X, Vol. 5, no 4, p. 301-313Article in journal (Refereed)
    Abstract [en]

    This research describes the predicted outcomes of a Kenyan Cloud School (KCS), which is a MOOC that contains all courses taught at the secondary school level in Kenya. This MOOC will consist of online, ongoing subjects in both English and Kiswahili. The KCS subjects offer self-testing and peer assessment to maximize scalability, and digital badges to show progress and completion to recognize and validate non-formal learning. The KCS uses the Moodle LMS with responsive web design to increase ubiquitous access from any device. Access is free and open, and the KCS intends to be a contextualized open educational resource for formal secondary institutions to support blended learning and a free source of non-formal education for lifelong learning. The expected outcomes are that this effort will reduce secondary school dropout rates, improve test scores, become a quality resource for blended learning, as well as validate and recognize lifelong learning in Kenya.

    Bridging the learning gap in Kenya with mobile learning: Challenges and future strategies2015In: Proceedings of E-Learn: World Conference on E-Learning in Corporate, Government, Healthcare, and Higher Education 2015 / [ed] curtis Ho & Grace Lin, University of Hawaii, USA, Chesapeake, VA: Association for the Advancement of Computing in Education, 2015, p. 1319-1325Conference paper (Refereed)
    Abstract [en]

    The overarching aim of this research was to study how mobile technology can catalyze informal learning and bridge the gap between informal and non-formal learning. In this study 30 Kenyan elite runners were equipped with a simple Android smartphone and free Internet for one year. The original research project focused on studying how a smartphone in the hands of impoverished Kenyans could assist and enhance informal learning. This project used log data, workshops and interviews to track the users’ progress. During the course of the study a huge desire for more formalized learning developed. Thus, a non-formal course on Human Rights was developed and made available for all Kenyans via any Internet connected device. In this way the intersection of these two projects provided an opportunity to satiate interests gained from unguided informal learning with structured non-formal learning. Key findings were that the smartphone empowered marginalized groups, augmented informal learning opportunities, and provided a means to bridge informal and non-formal learning to deliver educational opportunities to any device in the form of a non-formal MOOC. This research made a significant impact in the participants’ lives and the most common statement from the interviews was the statement “it helps us a lot”.

    Do-It-Yourself Learning in Kenya: Exploring mobile technologies for merging non-formal and informal learning2014Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The educational landscape is changing and a variety of technologies and techniques are blurring the lines between traditional and non-traditional learning. This change is substantial in low-income countries: individuals in developing countries have a great desire to educate themselves and improve their quality of life. Kenyans are adequately literate and accustomed to mobile technology despite being a largely impoverished, poorly educated populace. Kenya represents an optimal setting in which to research the use and feasibility of modern mobile and educational technologies. The broad aim of this dissertation is to explore how mobile devices can catalyze and enhance both informal and non-formal learning. In particular, this dissertation explores how technologies and concepts such as mobile web apps, Massive Open Online Courses (MOOCs), and learning incentives via a smartphone specifically affect informal and non-formal learning in Kenya. The primary research question is how can learning efforts that utilize mobile learning, MOOCs, and learning incentives combine non-formal and informal learning to develop and contribute to a do-it-yourself (DIY) approach to learning in Kenya? The primary method is action research. The first contribution of this dissertation is the finding that mobile web apps are currently better suited for data exchange than producing new content. The second contribution is the finding that a smartphone can enhance informal learning in a developing country with little or no scaffolding. The third contribution is the finding that non-formal learning efforts as a MOOC are shown to be a viable means of delivering non-formal learning in a developing country via a smartphone. The fourth contribution is the finding that the use of incentives such as digital badges provide a means by which to validate non-formal learning and contribute to a DIY attitude towards learning creation, where individuals can freely complement or replace a traditional curriculum.

    Native Apps Vs. Mobile Web Apps2013In: International Journal of Interactive Mobile Technologies (iJIM), E-ISSN 1865-7923, Vol. 7, no 4, p. 27-32Article in journal (Refereed)
    Abstract [en]

    The extensive growth and expansion of smartphones and tablets and therewith the use of mobile web applications that utilize HTML5 and related technologies are frequently discussed and debated in media as possible replacements for native applications. The aim of this study was to explore the viability of replacing native applications with mobile web applications in a developing country setting. Two mobile web applications were developed. The first mobile web application tracked runs and the second mobile web application was a booking system for scheduling "slum runs". The subjects who tested these apps were elite, semi-professional Kenyan runners primarily from the Kibera slum area outside of Nairobi. After a 6-month test period the participants concluded and results indicated that the mobile web application for tracking runs performed poorly compared to native applications due to poor GPS performance, while the mobile web application for booking slum runs performed well. The conclusion from this study is that mobile web applications that require hardware interaction such as using the GPS, GPU, or camera are not yet viable alternatives for native applications. However, mobile applications that only require a native interface and content consumption are suitable substitutes for native applications.

    No University Credit, No Problem?: Exploring Recognition of Non-Formal Learning2014In: 2014 IEEE Frontiers in Education Conference Proceedings, IEEE Computer Society, 2014, 2420-2426, 2014, p. 2420-2426Conference paper (Refereed)
    Abstract [en]

    Massive Open Online Courses (MOOCs) are disrupting traditional, higher education and redefining how learning takes place online. These open courses typically offer some form of recognition, such as a certificate of completion and/or digital badge, to recognize, validate, and in some cases even accredit learning. A general problem with MOOCs is the uncertainty regarding the use and goals of recognition, validation, and accreditation (RVA), and participants' acceptance and perception of such techniques. This research effort addresses this problem by exploring course partici-pants' attitudes and levels of acceptance of non-formal learning recognition compared to traditional university credit in both devel-oped and developing countries. The actual study uses both certifi-cates of completion and digital badges to recognize and validate learning in an introductory, university level course in web pro-gramming using HTML5/CSS. The course is available to anyone, but was specifically marketed to participants from Sweden and Kenya. Empirical data was gathered using interviews and online surveys in the course. The preliminary results are that participants from developing countries value digital recognition to a greater extent than their counterparts in Europe. However, both Swedes and Kenyans see open courses with digital recognition as a com-plement to traditional learning to individually construct an educa-tion.

    Putting a MOOC for Human Rights in the Hands of Kenyans: The Haki Zangu Case for Non-Formal Learning2014In: The Electronic Journal of Information Systems in Developing Countries, E-ISSN 1681-4835, Vol. 65, no 3, p. 1-17Article in journal (Refereed)
    Abstract [en]

    The research goal of this project was to explore the use and effects of non-formal education and incentives in the context of a developing country. The practical aim of this project was to create, implement, and evaluate a platform about human rights that was available to any Kenyan for free in order to increase knowledge and engagement. Therefore, a non-formal massive open online course (MOOC) about human rights was designed and launched. The course was free and open to anyone in Kenya and offered both a digital badge and certificate from Stockholm University in Sweden upon completion. The course was called Haki Zangu (Kiswahili for "My Rights"), and it explored how using incentives such as a digital badge and certificate of completion affected learning outcomes. This course offered ubiquitous access based on principles of responsive web design and used audio recordings of the entire course content. The course is perpetual and still on-going, but after six months there were 160 participants who had enrolled, and ten participants had completed the course and received certificates and digital badges. The participants showed extensive enthusiasm and engagement for human rights issues, and they expressed desires to learn more and further spread knowledge about human rights. The current findings suggest that the availability of digital badges and certificates increased interest for participation and positively affected learning outcomes. Moreover, the use of a Massive Open Online Course (MOOC) format with incentives proved successful, combined with the contextualization and accessibility of the course content. Furthermore, the technical platform proved adequate for disseminating education for free in a developing country, and allowed for unencumbered access regardless of device. Lastly, a key challenge for future non-formal learning efforts in developing countries is the cost of Internet access.

    MOOCs for Professional Teacher Development2014In: Proceedings of Society for Information Technology & Teacher Education International Conference 2014 / [ed] M. Searson & M. Ochoa, Chesapeake, VA: AACE , 2014, p. 1580-1586Conference paper (Refereed)
    Abstract [en]

    A MOOC is a trending concept in education that is disrupting traditional methods oflearning consumption. The emergence and use of MOOCs for professional teacher development isstill uncommon, but on the verge of gaining a foothold. Research regarding MOOCs typicallyfocuses on impacts for higher education and lifelong learning. However, the specific intersection ofMOOCs and professional teacher development is poorly researched. This concept papercontemplates the benefits and drawbacks of using MOOCs for professional teacher developmentand calls for more practical studies and explorative research. This paper also speculates on the basicMOOC design criteria and principles needed to maximize engagement and course completion,which are currently common issues with general MOOCs. The conclusion is that MOOCs can be acost- and resource-effective means to deliver quality education in order to further professionalteacher development. However, possible risks are employers' reluctance to accept MOOCaccreditation as equivalent professional development and the lack of relevant MOOC courses forprofessional development.
