    Measuring the Immeasurable?  The Intangible Benefits of Digital Information2019In: Proceedings of the 52nd Hawaii International Conference on System Sciences  2019, Hawaii International Conference on System Sciences , 2019, p. 6176-6185Conference paper (Refereed)
    Abstract [en]

    The benefits of digital information are mostly viewed as intangible, meaning that they can be hard to measure. This lack of measurements makes the benefits difficult to compare and communicate, creating problems for e.g. decision-making and the strategic development of specific digital information. Therefore, I conducted a literature review to find out how the combination of intangible benefits and measurements are dealt with in the information systems field. I found that we measure the intangible benefits of information systems or information technology. Here, the measurement method is divided into input, rule, and output. The input consists of predetermined individual benefits, areas of predetermined benefits, or interpreted benefits from respondents. The rule follows an accepted theory or contextual adjusted rules, and the output (benefit) can be seen as either financial or non-financial. The avenue for further research focuses on the digital information as the primary resource, not information systems or information technology.

    Critical Factors for Human Computer Interaction of eHealth for Older Adult2019In: Proceedings of the 2019 the 5th International Conference on e-Society, e-Learning and e-Technologies, Vienna: Association for Computing Machinery (ACM), 2019, Vol. 5, p. 58-62Conference paper (Refereed)
    Abstract [en]

    The percentage of older adults increases globally with an increased need for medical care. To support the idea of successful active aging, e-health seems to be an interesting concept. This study was conducted as a systematic literature study, with the aim to identify and discuss determinant factors in the Human computer interaction of eHealth for older adults. The important main research question to answer was: What are the critical challenges to address for an improved human computer interaction in technology enhanced health care systems for older adults? Findings show that there are several critical factors to consider, with trust, personal integrity, technological acceptance, e-health literacy and accessibility of ICT as the most determinant. If the found challenges are addressed, it might be possible to achieve the identified aim of independent living. The recommendation is a human computer interaction that is elderly centred, and involves the elderly users in the design process. However, no ICT enhanced system will be user-friendly enough to take away the need for social and technological support.

    Testbed requirements for technology enhanced stroke rehabilitation to support independent living2019Conference paper (Refereed)
    Abstract [en]

    An identified global phenomenon is that, as the percentage of older adults increases, new challenges arise for medical care and rehabilitation. Several research studies have presented e-health as a promising concept to support the idea of independent living among patients with chronic diseases. The Mid Sweden region has a relatively old population and is a region where people live with long distances to the nearest hospital or health care centres. This study had a focus on defining testbed requirements for a technology enhanced stroke rehabilitation adapted to the specific region. The focal research question to answer in this study was: What are the requirements and their associated benefits and barriers of using technology-enhanced systems instead of traditional techniques for stroke rehabilitation in the Mid Sweden region? With Design Science as the overall research strategy, data was collected by semi-structured interviews with key stakeholders in the field of stroke rehabilitation. A deductive thematic analysis was conducted where important themes were grouped into the four main requirement categories of: Technical, Human-computer-interaction, Clinic and Sustainability. Beside the more specific requirements, an interesting finding was the division of stroke rehabilitation into the categories motoric, cognitive and speech rehabilitation; also, how technology enhanced solutions might be used in these categories. Each category has a potential for a successful use of technology enhanced services, but as the standard procedure in traditional stroke rehabilitation each patient needs a personalised treatment.

    Chat yourself into the society: The development of an audio-visual online environment for the newly arrived2019In: INTED2019 Proceedings, Valencia: The International Academy of Technology, Education and Development, 2019, Vol. 13, p. 553-557Conference paper (Refereed)
    Abstract [en]

    Large groups of refugees have arrived in Sweden during the last years with a peak in 2015 when there were around 1.3 million asylum applications. Many of the newly arrived are still not yet integrated into the Swedish society and language skills is a key factor for a successful inclusion and integration process. There is a need for new digital language learning tools, not least for informal self-learning. The aim of the study is to describe and discuss the development and evaluation of an audio-visual online tool for informal language learning as a complement to formal language training.

    The overall research strategy has been action research with a qualitative investigation where data were gathered in a mix of usability tests, observations and interviews. Main informants were 12 students from three separate courses on Swedish for newly arrived. Since the group of informants constitute an exposed group, personal details have been kept as anonymous as possible.

    Findings indicate that several design concepts were useful and appreciated by the test group, but several users wanted an alternative to the Facebook based login. Gamification seemed to be a promising way to increase motivation, and many participants perceived that a feature with direct translation of messages would be a good way to improve the language learning. Furthermore, there were requests for tool mechanisms to filter conversation partners by gender and by interests.

    Undersökning av webbsidors säkerhet vid användning avFacebook Login: Vidareutveckling och analys av OAuthGuard2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Single Sign-On (SSO) is an authentication process that allows

    a developer to delegate the authentication responsibility to a

    dedicated service. OAuth 2.0 is an authorization framework

    that often serves as a base for authentication layers to be built

    upon that in turn allows for SSO. An identity provider is the

    service that is responsible for handling user credentials and

    the authentication, two common identity providers are

    Google and Facebook that implement SSO with the

    authentication layers OpenID Connect respectively

    Facebooks own authentication layer. It has been shown that

    many clients using OAuth 2.0 as base for SSO make faulty

    implementations leading to security issues, a number of

    studies has proposed solutions to these issues but faulty

    implementations are continually being made. To create

    various tools to promote security in these contexts is a

    method where OAuthGuard has been developed with the

    vision to also directly protect the common website user

    directly from the browser. OAuthGuard has been used in an

    earlier study to analyze the security of clients using Google

    SSO and discovered that 50% of the analyzed clients had

    flaws, no comparable study has been done for clients using

    Facebook SSO, which is the second largest third party log in

    variant. This study made a comparable investigation for

    Facebook SSO clients with a further developed version of

    OAuthGuard and found that these clients suffer from flaws

    with a similar trend as the previous study with Google-SSO

    clients, although fewer Facebook-SSO clients suffer from

    these flaws. When further developing OAuthGuard a

    dumber of difficulties was discovered and the future of these

    kind of tools needs to be investigated. Further analysis needs

    to be done to assess if Facebook-SSO should be

    recommended over Google-SSO from a security perspective

    and also further exploration of new methods to promote

    security needs to be done.

    Critical Imaginaries and Reflections on Artificial Intelligence and Robots in Postdigital K-12 Education2019In: Postdigital Science and Education, ISSN 2524-4868, 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 operates, 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.

    Teacher Perception Of Obstacles And Opportunities In The Integration Of Programming In K-12 Settings2019In: EDULEARN19 Proceedings, Palma (Spain): The International Academy of Technology, Education and Development, 2019, Vol. 11, p. 350-356Conference paper (Refereed)
    Abstract [en]

    The act of programming can be traced back to the 19th century and Ada Lovelace. In the context of history, the idea to combine programming with mathematics and technology is not strange. Today programming is a much more widespread phenomenon. But the relevance of programming in mathematics and technology is still very obvious. However, with the mandatory addition of programming in K-12 setting a debate has been sparked concerning the impact on teaching activities. The aim of this study was to analyse and discuss possible obstacles and opportunities in integrating programming in K-12 settings from a teacher perspective. The two important main questions to answer were: 1) which are teachers' perceived obstacles and opportunities in the integration of programming in K-12 setting? 2) which are the differences and similarities in expectation between teachers with and without earlier programming experience?

    This study was carried out inspired of action research with the objective of improving an existing programming course for mathematic and technology teachers. Action research is a strategy that do not only strive to generate new knowledge but also has the aim to improve real world phenomena. Authors in this study had the double roles of being teachers and researchers, with the idea of establishing a cyclical process where course participants feedback should lead to extensions of the future course versions. Data were collected in the teacher training course and consist of 44 submitted essay answers on the question: In which aspects might programming be a positive and/or negative enhancement of you daily teaching? Collected data were grouped into categories with the use of content analysis.

    Results indicate that there are both perceived opportunities and perceived obstacles among teachers concerning integrating programming in mathematics and technology. An obvious finding was the mix of positive and negative attitudes in the vast majority of essays. In the category of obstacles many teachers brought up the risk of time trouble in both their professional development and in their teaching activities. In the category of opportunities several teachers mentioned the potential of programming as a new and motivating learning tool in their subjects. Finally, it seems important for the participants to get concreate takeaways from the course that could be used in their daily teaching activities.

    Teacher Challenges And Choice Of Programming Tools For Teaching K-12 Technology And Mathematics2019In: Education and new developments (END2019) / [ed] Mafalda Carmo, Porto, Portugal: inScience Press, 2019, Vol. 1, p. 431-435Conference paper (Refereed)
    Abstract [en]

    A current ongoing process in many countries today is to implement programming in K-12 education. With this comes challenges for the involved teachers on how to best teach and integrate programming in their subjects. On the other hand, the introduction of programming could also open opportunities for programming as a new and improved way of learning and understanding technology and mathematics. For Swedish K-12 teachers this should be rapidly implemented, but without any concrete guidelines for how or for which tools to use. The aim of this study was to explore teachers' perceptions of learning and integrating programming in technology and mathematics, and their preferences of programming tools. 

    The overall research strategy was a case study approach, with two instances of a programming course as the case study units. In both course instances the main choice has been between block programming with Scratch, and textual programming with Python. Data was collected in a combination of submitted essays, programming assignments and workshop observations. Findings from a content analysis of the submitted essays have been compared to workshop observations, and to the analysis of programming assignments. 

    Results suggests that the main challenge in learning and integrating programming is the perceived time trouble. In parallel, many teachers highlight the potential benefits of renewing their teaching and learning sessions with programming-based problem solving. Considering the choice between block programming and textual programming several teachers brings up the idea of combining the two rather than excluding one of them. Furthermore, there seems to be minor differences in the preferences of programming tools between teachers with different subjects and different age groups of students. Finally, the most positive finding is the improved self confidence that many teachers show, when their own ability to manage programming in their classrooms increase after learning the fundamentals of programming.

    En enkätstudie rörande systemutvecklingsansatser och   metodologier2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study has   focused on system development approaches and system development   methodologies. The purpose of the study has been to present a view on the   current situation of different development approaches (agile, traditional,   iterative and hybrid) and methodologies by highlighting the situation from a   number of perspectives. Questions that are answered are: which system   development approaches and methodologies that can be said to be most   frequently used based on the respondents, if the mentioned approaches can be   given certain characteristics based on a selection of factors and the   respondents' attitude towards the approach they practice. The study has been   conducted as a survey where the answers have been obtained via social media.   The result shows that agile methodologies dominate and that they are often   included in various forms of hybrid and agile approaches. Furthermore, it has   not been possible to create an in-depth knowledge of the approaches based on   the selected factors. Finally, it is noted that project members who practice   an agile approach have a great confidence in the approach and have a strong   conviction that it contributes to increase the quality of the software.

    Orchestrating learning as an emergent practice in the use of location-based games with mobile devices2019In: Emergent practices and material conditions in learning and teaching with technologies / [ed] Teresa Cerratto Pargman and Isa Jahnke, Cham, Switzerland: Springer, 2019, p. 163-180Chapter in book (Refereed)
    Abstract [en]

    This study discusses the inclusion of location-based games and mobile devices in an educational setting that embraces both indoor and outdoor sessions. The study was built on a framework including learning as a social and collaborative phenomenon. Two case units, in terms of a 5th grade Social Science class and a 6th grade Mathematics class, were included in the study. Each case unit embraced an indoor preparing session, an outdoor session including mobile devices and the location-based game Pokémon GO, and an indoor follow-up session. The chapter aims at contributing to the understanding of how students and teachers together, in an emergent practice of orchestrating learning, apply mobile devices and location-based games in their educational setting. From this aim, the following research question unfolds: How could location-based games and mobile devices be applied by students and teachers to orchestrate learning in middle school settings? Data were gathered by semi-structured group interviews and video recordings with 20 students and two teachers. Moreover, documents such as lesson plans were included in the dataset. In the study, it was found that students and teachers participated in a shared and emerging practice of orchestrating learning and teaching. In this practice students and teachers acted as co-designers to orchestrate the application of location-based games and mobile devices in the educational setting. Findings suggest that an orchestration including a combination of a collaborative approach to learning, location-based games and activities that embrace outdoor and indoor sessions has the potential to vitalise and enhance traditional classroom-based education. However, there is not a guarantee that all students will concentrate on the given task, and just as in an ordinary classroom setting, teaching and learning also require careful orchestration.

    Teachers’ beliefs about professional development: Supporting emerging networked practices in higher education2019In: Networked professional learning: Emerging and equitable discourses for professional development / [ed] Littlejohn, Allison; Jaldemark, Jimmy; Vrieling-Teunter, Emmy and Nijland, Femke, Springer, 2019, p. 147-164Chapter in book (Refereed)
    Abstract [en]

    During recent decades society has gone through changes related to social and technological development. These changes have impacted higher education. This has led to emerging networked practices that professionals and the organisations they work within need to respond to. An answer to this challenge to higher education is efforts in professional development. This chapter discusses teachers’ beliefs about such professional development. Particularly, it focuses on how networked practices in higher education are supported and fostered by professional development projects. The study was based at a Swedish university and included the dissemination of beliefs of teachers from three different departments that participated in two development projects. The data materials were collected by using semi-structured interviews from a sample of 19 teachers. The results revealed that professional development concerns beliefs on both individual and collective levels. Within these levels teachers related their professional development to both social and technological networks.

    Identifying Traces of Boundary Object Properties in Data Hub Development Narratives: Two Cases from Scandinavian Electricity Market2019In: AMCIS 2019 Proceedings, 2019Conference paper (Refereed)
    Abstract [en]

    Digital technology enables multi-relational collaborations between parties with different experiences, knowledge, values, and goals. Regarding digital technology triggering enterprise transformation, boundary object as theoretical model for understanding such differences in development is not well understood, especially the ways boundary object emerges in practice. We inquired what traces of boundary object properties can be identified in data hub development narratives. An interpretive approach was chosen for understanding experience-centered narratives that origins from interviews conducted in two separate studies of national development of data hubs for the electricity market in Denmark and Sweden respectively. Through a literature review covering boundary objects, nine prosperities were chosen for the theoretical frame used in the interpretation of the narratives. The conclusion was that boundary object properties were part of the narratives of the data hub developments early on in the in-use taking processes and even before the digital artifact was taken into use.

    BusinessIntelligence Systems effekter på sjukvården: Utvecklingoch test av modell2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Swedish   healthcare system today has longer queues than before, low treatment rates   and lack of accessibility, treatment and service. Business Intelligence   System (BIS) purpose is to support organizations and businesses in different   types of decision-making that in turn can make the operations more efficient.   The purpose of this thesis is to develop and test a model that describes the   effects that BIS have on the healthcare system according to previous research   on Swedish healthcare staff and their experiences of these systems. The study   has been carried out through qualitative interviews with respondents who work   with BIS in the Swedish healthcare system. A model developed from previous   research has according to the purpose of this study been developed and tested   against the collected empirical data to see if the effects that the previous   research has identified are in line with what Swedish healthcare staff has identified.   The entire model which consists of BIS basic functionality and BIS effects on   healthcare has been tested against another respondent who did not participate   on any interview but instead performed a thorough analysis of the whole   model. What were tested by this respondent were the model’s flow, structure   and constituents. The result of this study came to the conclusion that the   basic functionality of the model developed and the identified effects are in   accordance with the effects identified by the Swedish healthcare staff they   receive from the BIS within their work.

    Augmented Education: Location-Based Games for Real-World Teaching and Learning Sessions2019In: Augmented Reality Games I / [ed] Vladimir Geroimenko, Springer, 2019, p. 217-235Chapter in book (Refereed)
    Abstract [en]

    GPS-equipped smartphones have enabled the construction of location-based games. In augmented reality (AR), fantasy worlds are mapped to real-world settings. Two location-based AR games that use historical markers as points of interest are Ingress and Pokémon GO. This chapter describes and discusses how PokéStop statues in Pokémon GO can be used in primary school outdoor sessions. A case study was conducted on how fifth-grade students learned about local history, social sciences and humanities during game sessions. Findings suggest that AR could be an inspiring  extension in educational settings, if activities are aligned to the surroundings and learning objectives and outdoor gaming activities are followed up in more traditional classroom sessions.

    Teacher Attitudes Towards The Integration Of Programming In Middle School Mathematics2019In: INTED 2019 Proceedings, Valencia: The International Academy of Technology, Education and Development, 2019, p. 701-706Conference paper (Refereed)
    Abstract [en]

    Involving computer programming in primary school is an urgent issue in many countries, and in Sweden this should be done during 2018. In Mathematics this will a rapid and mandatory process for teachers that often lack programming proficiency. There are several studies conducted on the student impact of programming and the potential learning outcomes. Less has been published on the teacher attitudes and the teacher perspective of programming in primary school. The aim of this study was to explore and discuss teacher attitudes towards the introduction of programming in middle school.

    The study was carried out as a qualitative cross-sectional study with the idea of capturing the attitudes and beliefs amongst middle school teachers during the second half of the 2018 spring semester. Eight Mathematic teachers were selected for semi-structured interviews that were carried out by distance with rich media communication tools. Audio-recorded answers were analysed and divided into five predefined categories in a deductive thematic analysis. Interviewees have been kept as anonymous as possible through the process, and they all participated on a voluntary basis with the option to quit the interviews immediately at any moment.

    A main finding was that the majority of teachers are positive about the introduction of programming in middle school mathematics, although some challenges and shortcomings were identified. Furthermore, the interviewed teachers’ beliefs are that computer programming could have a positive impact on students’ mathematic skills through improved their problem-solving ability and improved their logical thinking. Some teachers also brought up the idea of programming as a way of creating energy and motivation in middle school mathematics. However, the fast introduction of programming will probably create stress on teachers without earlier programming experience. Teachers’ recommendation for facilitating and coping with stress is to provide courses in fundamental programming as soon as possible.

    Tiny Security: Evaluating energy   use for security in an IoT application2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    IoT devices are   increasingly used in the process of gathering scientific data. In   environmental monitoring IoT devices can be used as remote sensing devices to   collect information about e.g. temperature. To keep data reliable, various   security aspects have to be considered. Constrained devices are limited by   memory size and battery life, a security solution has to be developed with   this in mind. In this study an IoT security solution was developed in collaboration   with a research group in environmental science at Umeå University. We   selected commonly used algorithms and compared them with the goal to provide   authentication and integrity for an IoT application, while minimizing energy   use running on an Atmega 1284P. The results showed that the encryption   algorithm AES-256-GCM is a good choice for a total security solution.   AES-256-GCM provides authenticated encryption with additional data while, in   relation to the other tested algorithms, using energy at a low level and   leaving a small program size footprint.
